C# Code:

c.OnComponentChanging(form, null);//通知窗体正在新增控件服务

form.Controls.Add(button);//Form.Controls.Add, 生成持久化代码

c.OnComponentChanged(form, null, null, null);//通知窗体修改服务已完成

C# Code:

private void OnGenerateButtonCode(object sender, EventArgs e)
{
   //
   //在窗体上加入一个Button组件,host.RootComponent=Form
   //
   //取出窗体设计器
   IDesignerHost host = (IDesignerHost)this.GetService(typeof(IDesignerHost));
   IComponentChangeService c = (IComponentChangeService)this.GetService(typeof(IComponentChangeService));
   
   Form form = (Form)host.RootComponent;//RootComponent: 根组件，指Form
   DesignerTransaction tran = host.CreateTransaction();//创建事务
   
   //创建按钮组件
   Button button = (Button)host.CreateComponent(typeof(Button));
   button.Text = "www.CSFramework.com";
   button.Location = new Point(50, 50);
   button.Size = new Size(150, 30);
   
   c.OnComponentChanging(form, null);//通知窗体正在新增控件服务
   form.Controls.Add(button);//Form.Controls.Add, 生成持久化代码
   c.OnComponentChanged(form, null, null, null);//通知窗体修改服务已完成
   
   tran.Commit();//提交事务
   
   MessageBox.Show("已生成" button.Name "的代码！请打开frmTester.Designer.cs文件查看．");
