下面介紹一種只需對(duì)現(xiàn)有代碼做較小改動(dòng)的方法。

在 Visual Studio 的設(shè)計(jì)視圖中，如果在 Properties 窗口中改變了程序的默認(rèn)界面語(yǔ)言（Language），我們會(huì)注意到無(wú)論是工程還是窗體對(duì)應(yīng)的 .Designer.cs 文件都會(huì)有顯著的改變。比如，我們創(chuàng)建一個(gè)叫 MyForm 的 form，并且添加一個(gè)叫 MyButton 的按鈕。

在改變窗體 Properties 中的 Language 屬性之前， .Designer.cs 代碼文件中的 InitializeComponent 方法的內(nèi)容大致如下：

• private void InitializeComponent()
• {
• this.myButton = new System.Windows.Forms.Button();
• this.SuspendLayout();
• //
• // myButton
• //
• this.myButton.Location = new System.Drawing.Point(100, 200);
• this.myButton.Name = "myButton";
• this.myButton.Size = new System.Drawing.Size(75, 23);
• this.myButton.TabIndex = 0;
• this.myButton.Text = "My Button";
• this.myButton.UseVisualStyleBackColor = true;
• //
• // myForm
• //
• this.ClientSize = new System.Drawing.Size(292, 273);
• this.Controls.Add(this.myButton);
• this.Name = "MyForm";
• this.Text = "My Form";
• this.ResumeLayout(false);
• }

?

而在改變了窗體 Properties 中的 Language 屬性之后，工程中除了默認(rèn)的 .resx 文件之外，還會(huì)自動(dòng)添加一個(gè) .zh-CHS.resx 文件（假設(shè)我們將 Language 改變?yōu)?Chinese (Simplified)）。另外，.Designer.cs 文件中的 InitializeComponent 方法也會(huì)改變成：

• private void InitializeComponent()
• {
• System.ComponentModel.ComponentResourceManager resources
• = new System.ComponentModel.ComponentResourceManager(typeof(MyForm));
• this.myButton = new System.Windows.Forms.Button();
• this.SuspendLayout();
• //
• // myButton
• //
• this.myButton.AccessibleDescription = null;
• this.myButton.AccessibleName = null;
• resources.ApplyResources(this.myButton, "myButton");
• this.myButton.BackgroundImage = null;
• this.myButton.Font = null;
• this.myButton.Name = "myButton";
• this.myButton.UseVisualStyleBackColor = true;
• //
• // myForm
• //
• this.AccessibleDescription = null;
• this.AccessibleName = null;
• resources.ApplyResources(this, "$this");
• this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
• this.BackgroundImage = null;
• this.Controls.Add(this.myButton);
• this.Font = null;
• this.Icon = null;
• this.Name = "myForm";
• this.ResumeLayout(false);
• }

?

我們注意到改變 Language 屬性之后，代碼的主要變化有：

• ComponentResourceManager resources = new ComponentResourceManager(typeof(MyForm));
• resources.ApplyResources(this.myButton, "myButton");
  resources.ApplyResources(this, "$this");

另外，設(shè)置控件屬性（比如顯示文字 Text，控件大小 Size，顯示位置 Location 等）的代碼都沒有了。也就是說(shuō)設(shè)置控件屬性的代碼都是由 resources.ApplyResource 方法來(lái)完成的。那么在我們想改變 WinForm 程序的界面顯示語(yǔ)言的時(shí)候，能不能直接調(diào)用 ApplyResources 方法呢？答案是肯定的。

為 myButton 添加 Click 事件的事件處理函數(shù)：

• private void myButton_Click(object sender, EventArgs e)
• {
• int currentLcid = Thread.CurrentThread.CurrentUICulture.LCID;
• currentLcid = (currentLcid == 2052) ? 1033 : 2052;
• ?
• // Changes the CurrentUICulture property before changing the resources that are loaded for the win-form.
• Thread.CurrentThread.CurrentUICulture = new CultureInfo(currentLcid);
• ?
• // Reapplies resources.
• ComponentResourceManager resources = new ComponentResourceManager(typeof(MyForm));
• resources.ApplyResources(myButton, "myButton");
• resources.ApplyResources(this, "$this");
• }

?

當(dāng)程序運(yùn)行的時(shí)候，點(diǎn)擊窗體上的 myButton 按鈕，窗體的界面顯示語(yǔ)言就會(huì)在英語(yǔ)和簡(jiǎn)體中文之間互相切換。
