因公司业务需要，需要将原有的ERP系统加上支持繁体语言，但不能改变原有的编码方式，即：普通程序员感受不到编码有什么不同。经过我与几个同事的多番沟通，确定了以下两种方案：

方案一：在窗体基类中每次加载并显示窗体时，会自动递归遍历含文本显示的控件（Button,CheckBox,GroupBox,Label,LinkLabel,TextBox,StatusStrip,TabPage,ToolStrip,RadioButton,DateTimePicker,DataGridView,CheckedListBox，TreeView,MenuStrip），并根据不同的控件类型的文本属性调用简繁转换方法进行转换并重新设置新的相应文本属性的内容（比如：繁体内容）

优点：编码简单，对普通程序员的编码无影响（除窗体类的基类由Form类变成MyStyleFormBase类）；

缺点：因每次打开窗体都需要遍历控件并进行简繁转换，如果界面上的控件较多，则可能导致打开窗体较慢，影响用户体验，且子控件的文本内容改变时需程序员手动通知，无法自动感知并转换。

具体实现思路如下：

一.对Form类进行二次封装（继承），定义一个MyStyleFormBase类，并在里面加入每次加载并显示窗体类型时，会自动递归遍历含文本显示的控件，并根据不同的控件类型的文本属性调用简繁转换方法进行转换并重新设置新的相应文本属性的内容，这样当所有的窗体都继承MyStyleFormBase类时，均默认就实现了遍历与转换的过程，程序员无需再次编码，甚至都无需知道存在遍历与转换的过程，从而提高了代码的复用性，具体代码如下：

    public class MyStyleFormBase : Form
    {
        public MyStyleFormBase()
        {
            if (!Thread.CurrentThread.CurrentUICulture.Name.Equals("zh-CHS", StringComparison.OrdinalIgnoreCase)) //如果是简体，则无需转换
            {
                base.TextChanged += MyStyleFormBase_TextChanged;
                base.Shown += MyStyleFormBase_Shown;
            }
        }

        private void MyStyleFormBase_TextChanged(object sender, EventArgs e)
        {
            this.Text = LanguageHelper.GetLanguageText(this.Text);
        }

        private void MyStyleFormBase_Shown(object sender, EventArgs e)
        {
            LanguageHelper.SetControlLanguageText(this);
            base.ControlAdded += MyStyleFormBase_ControlAdded;
        }

        private void MyStyleFormBase_ControlAdded(object sender, ControlEventArgs e)
        {
            LanguageHelper.SetControlLanguageText(e.Control);
        }

        /// <summary>
        /// 强制通知子控件改变消息
        /// </summary>
        /// <param name="target"></param>
        protected virtual void PerformChildrenChange(Control target)
        {
            LanguageHelper.SetControlLanguageText(target);
        }

        /// <summary>
        /// 弹出消息框
        /// </summary>
        /// <param name="text"></param>
        /// <param name="caption"></param>
        /// <param name="buttons"></param>
        /// <param name="icon"></param>
        /// <param name="defaultButton"></param>
        /// <returns></returns>
        protected DialogResult MessageBoxShow(string text, string caption, MessageBoxButtons buttons = MessageBoxButtons.OK, MessageBoxIcon icon = MessageBoxIcon.None, MessageBoxDefaultButton defaultButton = MessageBoxDefaultButton.Button1)
        {
            return MessageBox.Show(LanguageHelper.GetLanguageText(text), LanguageHelper.GetLanguageText(caption), buttons, icon, defaultButton);
        }
    }

代码逻辑简要说明：

1.当当前UI的文化区域不为中文简体时（因为本程序本身都是基于简体开发的），就订阅窗体显示事件Shown及窗体标题改变事件TextChanged，作用：当窗体显示时，则会遍历控件并转换为繁体，当标题的文本改变时，也会自动转换为繁体；

2.当窗体显示后订阅窗体的控件增加事件ControlAdded，作用：当窗体显示后，若后续存在代码增加控件时，会自动将控件及其子控件进行繁体的转换，保证一个都不漏；

3.增加一个消息提示框方法，目的是弹出消息窗口前能够将简体文本转换成繁体文本；

4.增加一个强制通知子控件改变消息的方法PerformChildrenChange，当某个控件的文本内容或增加子控件发生时，由于窗体本身无法捕获到，故需要调用该方法来遍历与转换子控件的文本内容；（感觉这里不太好，但目前没有更好的办法，如果大家有更好的办法，欢迎留言评论）

 二、LanguageHelper：语方转换公共类（目前仅支持简繁转换，依赖于：ChineseConverter.dll）代码如下：

    public class LanguageHelper
    {
        #region 简繁体转换
        /// <summary>
        /// 内容的语言转化
        /// </summary>
        /// <param name="parent"></param>
        public static void SetControlLanguageText(System.Windows.Forms.Control parent)
        {
            if (parent.HasChildren)
            {
                foreach (System.Windows.Forms.Control ctrl in parent.Controls)
                {
                    SetContainerLanguage(ctrl);
                }
            }
            else
            {
                SetLanguage(parent);
            }
        }
        #endregion
        #region 控件简繁体语言转换

        /// <summary>

    }

该类逻辑很简单，就是从一个父控件开始，遍历所有的子控件，并根据不同的控件类型将控件相应的文本内容转换成简体或繁体，调用方法：SetControlLanguageText

以上二步就实现了多语言的支持了（准确的说是简繁转换），应用到项目中很简单，只需将窗体默认的基类Form改成：MyStyleFormBase即可，如：public partial class FormTest : MyStyleFormBase

方案二：由控件依据当前区域信息+缓存语言字典直接实现各控件自行转换

优点：无需遍历，各控件自行根据区域信息自支转换，因此效率较高，对普通程序员的编码无影响（除窗体类的基类由Form类变成MyStyleFormBase类外，还需要使用支持多语言的控件，这些控件均由普通控件二次封装得来，保留原有的所有属性及事件）；

缺点：需将所有带文本显示的控件（如：Button,CheckBox,GroupBox,Label,LinkLabel,TextBox,StatusStrip,TabPage,ToolStrip,RadioButton,DateTimePicker,DataGridView,CheckedListBox，TreeView）均进行二次封装，控件统一命名为：MyStyleXXX

 涉及的控件较多，编码相对复杂；

具体实现思路如下：

一.对Form类进行二次封装（继承），定义一个MyStyleFormBase类，里面加入对窗体标题进行修改时，能自动进行多语言转换功能，具体代码如下：

    public partial class MyStyleFormBase : Form
    {

        public MyStyleFormBase()
        {
            base.TextChanged += MyStyleFormBase_TextChanged;
        }

        private void MyStyleFormBase_TextChanged(object sender, EventArgs e)
        {
            if (!Common.IsChsLanguage())
            {
                this.Text = LanguageHelper.GetLanguageText(this.Text);
            }
        }

        /// <summary>
        /// 弹出消息框
        /// </summary>
        /// <param name="text"></param>
        /// <param name="caption"></param>
        /// <param name="buttons"></param>
        /// <param name="icon"></param>
        /// <param name="defaultButton"></param>
        /// <returns></returns>
        protected DialogResult MessageBoxShow(string text, string caption = "提示", MessageBoxButtons buttons = MessageBoxButtons.OK, MessageBoxIcon icon = MessageBoxIcon.None, MessageBoxDefaultButton defaultButton = MessageBoxDefaultButton.Button1)
        {
            if (!Common.IsChsLanguage())
            {
                text = LanguageHelper.GetLanguageText(text);
                caption = LanguageHelper.GetLanguageText(caption);
            }

            return MessageBox.Show(text, caption, buttons, icon, defaultButton);
        }
    }

代码逻辑很简单，就是订阅一个Form.TextChanged事件，以便当根据IsChsLanguage（判断是否为简体模式）判断不是简体时，则需进行Form.Text转换

二.定义多语言支持普通控件及容器控件接口（IMultiLanguageControl、IMultiLanguageContainerControl），具体代码如下：（此处仅是为了作一个规范，支持手动设置转换控件的文本内容）

    /// <summary>
    /// 支持多语言普通控件（无子控件）
    /// </summary>
    public interface IMultiLanguageControl
    {
        string DefaultLangText { get; }

        string CurrentLangText { get; set; }
    }



    /// <summary>
    /// 支持多语言容器控件（包含子控件）
    /// </summary>
    public interface IMultiLanguageContainerControl
    {
        Dictionary<object, string> DefaultLangTexts { get; }

        Dictionary<object, string> CurrentLangTexts { get; set; }

        Control this[string ctrlName] { get; set; }

        void SetItemCurrentLangText(string ctrlName, string langText);

        event EventHandler<ChildrenAddedEventArgs> ChildrenChanged;

    }



    public class ChildrenAddedEventArgs : EventArgs
    {
        public Dictionary<object, string> LangTexts { get; private set; }

        public ChildrenAddedEventArgs()
        {
            LangTexts = new Dictionary<object, string>();
        }

        public ChildrenAddedEventArgs(Dictionary<object, string> langTexts)
        {
            this.LangTexts = langTexts;
        }

        public string this[object key]
        {
            get
            {
                return LangTexts[key];
            }
            set
            {
                LangTexts[key] = value;
            }
        }
    }

三、实现支持多语言普通控件：基于原有标准控件（Button,CheckBox,GroupBox,Label,LinkLabel,TextBox,RadioButton,DateTimePicker）进行二次封装，实现IMultiLanguageControl接口，各控件代码如下：

以下是MyStyleButton定义代码，MyStyleCheckBox、MyStyleGroupBox、MyStyleLabel、MyStyleLinkLabel、MyStyleTextBox、MyStyleRadioButton里面的实现代码均相同

public partial class MyStyleButton : MyButton, IMultiLanguageControl
    {
        static Dictionary<string, string> LanDict = new Dictionary<string, string>();
        public MyStyleButton()
        {

        }
        public override string Text
        {
            get
            {
                if (!DesignMode && System.Threading.Thread.CurrentThread.CurrentUICulture.Name != "zh-CHS")
                {
                    if (LanDict.ContainsKey(DefaultLangText))
                    {
                        return CurrentLangText;
                    }
                    else
                    {
                        string langText = LanguageHelper.GetLanguageText(base.Text);
                        LanDict[base.Text] = langText;
                        return langText;
                    }
                }
                return base.Text;
            }
            set
            {
                base.Text = value;
            }
        }
        [Browsable(false)]
        [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
        public string DefaultLangText
        {
            get
            {
                return base.Text;
            }
        }
        [Browsable(false)]
        [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
        public string CurrentLangText
        {
            get
            {
                try
                {
                    return LanDict[DefaultLangText];
                }
                catch (Exception)
                {
                    return "";
                }
            }
            set
            {
                if (System.Threading.Thread.CurrentThread.CurrentUICulture.Name != "zh-CHS")
                {
                    if (LanDict.ContainsKey(DefaultLangText))
                    {
                        LanDict[DefaultLangText] = value;
                    }
                    else
                    {
                        LanDict.Add(DefaultLangText, value);
                    }
                }
            }
        }
    }

　　

二次封装这些控件的目的是：1.暴露统一的属性，便于直接遍历并赋值（需手动改变文本内容语言的情况）；2.当文本内容发生改变时，能够根据语言缓存字典，快速直接的自我简繁转换，无需再次遍历；

四、实现支持多语言容器控件：基于原有标准控件（StatusStrip,TabPage,ToolStrip,DataGridView,CheckedListBox，TreeView）进行二次封装，实现IMultiLanguageContainerControl接口，各控件代码如下：

MyStyleDataGridView：

    public partial class MyStyleDataGridView : MyDataGridView, IMultiLanguageContainerControl
    {
        static Dictionary<string, string> LanDict = new Dictionary<string, string>();
        Dictionary<object, string> cloumnHeaderTexts = new Dictionary<object, string>();

        public MyStyleDataGridView()
        {
            cloumnHeaderTexts.Clear();
            this.CellValueChanged += MyStyleDataGridView_CellValueChanged;
        }

        private void MyStyleDataGridView_CellValueChanged(object sender, DataGridViewCellEventArgs e)
        {
            if (e.RowIndex < 0)
            {
                if (System.Threading.Thread.CurrentThread.CurrentUICulture.Name != "zh-CHS")
                {
                    var headerCell = this.Columns[e.ColumnIndex].HeaderCell as DataGridViewColumnHeaderCell;

                    if (headerCell != null)
                    {
                        string headerCellValue = headerCell.Value.ToString();
                        if (LanDict.ContainsKey(headerCellValue))
                        {
                            headerCell.Value = LanDict[headerCellValue];
                        }
                        else
                        {
                            if (ChildrenChanged != null)
                            {
                                ChildrenAddedEventArgs args = new ChildrenAddedEventArgs();
                                args[headerCell] = headerCellValue;
                                ChildrenChanged(this, args);
                                LanDict[headerCellValue] = args[headerCell];
                                headerCell.Value = args[headerCell];
                                args = null;
                            }
                            else
                            {
                                string langText = LanguageHelper.GetLanguageText(headerCellValue);
                                LanDict[headerCellValue] = langText;
                                headerCell.Value = langText;
                            }
                        }
                    }
                }
            }
        }
