我也是初学,给个例子

Public Class Form1 Inherits System.Windows.Forms.Form

#Region " Windows 窗体设计器生成的代码 "

Public Sub New() MyBase.New()

'该调用是 Windows 窗体设计器所必需的。 InitializeComponent()

'在 InitializeComponent() 调用之后添加任何初始化

End Sub

'窗体重写处置以清理组件列表。 Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean) If disposing Then If Not (components Is Nothing) Then components.Dispose() End If End If MyBase.Dispose(disposing) End Sub

'Windows 窗体设计器所必需的 Private components As System.ComponentModel.IContainer
