DoubleAnimation中的'Completed'方法在哪里（WPF，VB.NET） [英] Where is the 'Completed' Method in DoubleAnimation (WPF, VB.NET)

问题描述

在我的WPF应用程序中，我遇到了一个很大的动画问题。我用代码实现淡出动画，但代码不理解'Completed'方法。 CSharp可以这样做。

In my WPF App, I got a big problem for animation. I realizing fade out animation with code, but the code didn't understand the 'Completed' Method. CSharp can do with like this.

anim.Completed += (s, _) => this.Close();

但VB.NET无法得到它。



你能帮我写下答案吗？ ： - ）

Can you help me for write the answer please? :-)

推荐答案

使用 AddHandler 在VB.NET中添加事件处理程序;

Use AddHandler to add event handlers in VB.NET;

Dim anim As DoubleAnimation = New DoubleAnimation

Private Sub MySub()
  Dim anim As DoubleAnimation = New DoubleAnimation

  AddHandler anim.Completed, Sub(s, e) Me.Close()
  ' Or
  AddHandler anim.Completed, AddressOf MyEventHandlingFunction
End Sub

Private Sub MyEventHandlingFunction()
  Me.Close()
End Sub
