方法二:
下面介绍一种只需对现有代码做较小改动的方法。
在 Visual Studio 的设计视图中,如果在 Properties 窗口中改变了程序的默认界面语言(Language),我们会注意到无论是工程还是窗体对应的 .Designer.cs 文件都会有显著的改变。比如,我们创建一个叫 MyForm 的 form,并且添加一个叫 MyButton 的按钮。
在改变窗体 Properties 中的 Language 属性之前, .Designer.cs 代码文件中的 InitializeComponent 方法的内容大致如下:
- 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);
- }
而在改变了窗体 Properties 中的 Language 属性之后,工程中除了默认的 .resx 文件之外,还会自动添加一个 .zh-CHS.resx 文件(假设我们将 Language 改变为 Chinese (Simplified))。另外,.Designer.cs 文件中的 InitializeComponent 方法也会改变成:
- 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, "$this");
- this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
- this.BackgroundImage = null;
- this.Controls.Add(this.myButton);
- this.Font = null;
- this.Icon = null;
- this.Name = "myForm";
- this.ResumeLayout(false);
- }
我们注意到改变 Language 属性之后,代码的主要变化有:
- ComponentResourceManager resources = new ComponentResourceManager(typeof(MyForm));
-
resources.ApplyResources(this.myButton, "myButton");
resources.ApplyResources(this, "$this");
为 myButton 添加 Click 事件的事件处理函数:
- 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");
- }
当程序运行的时候,点击窗体上的 myButton 按钮,窗体的界面显示语言就会在英语和简体中文之间互相切换。
