推荐答案

您可以使用：

AddHandler button.Click, AddressOf HandlerMethod

在VB中，你可以指定一个方法处理特定控件的特定事件，如果你不是在飞行创造它 - 你只需要的AddHandler 当你重（说）动态填充表格一组按钮。

In VB you can specify that a method handles a particular event for a particular control, if you're not creating it on the fly - you only need AddHandler when you're (say) dynamically populating a form with a set of buttons.

下面是一个简短但完整的例子：

Here's a short but complete example:

Imports System.Windows.Forms

Public Class Test

    <STAThread>
    Public Shared Sub Main()
        Dim f As New Form()
        Dim b As New Button()
        b.Text = "Click me!"
        AddHandler b.Click, AddressOf ClickHandler
        f.Controls.Add(b)
        Application.Run(f)
    End Sub

    Private Shared Sub ClickHandler(sender As Object, e As EventArgs)
        Dim b As Button = DirectCast(sender, Button)
        b.Text = "Clicked"
    End Sub

End Class

编辑：要关闭的形式，最简单的办法是让原始的控制形式：

To close the form, the simplest way is to get the form of the originating control:

    Private Shared Sub ClickHandler(sender As Object, e As EventArgs)
        Dim c As Control = DirectCast(sender, Control)
        Dim f as Form = c.FindForm()
        f.Close()
    End Sub
