我对委托的理解(VB.NET)

我刚接触委托,我觉的委托就相当于一个函数指针.

下面是我写的一个关于委托最简单的例子:

Form1是指一个窗体,TextBox1是指一个TextBox控件

Private Function HelloWorld() Function HelloWorld() As String

Return "Hello world"

End Function

Delegate Function myMethodDelegate() Function myMethodDelegate() As String

Dim MyDelegate As New myMethodDelegate(AddressOf HelloWorld)

Private Sub Form1_Load()Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Me.TextBox1.Text = MyDelegate()

End Sub
