如何在按钮单击后禁用按钮3秒，然后再次启用按钮

Question

如何在按钮单击后禁用按钮3秒并自行启用按钮？ VB.net

我想禁用按钮3秒，所以用户不会滥用系统。

Answer 1

如何在按钮单击后禁用按钮3秒并单独启用 按钮？

最简单的形式：

Private Async Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click 
    Button1.Enabled = False 

    ' ... do something ... 

    Await Task.Delay(3000) 

    Button1.Enabled = True 
End Sub 

如果 “有所作为” 部分耗时的话，也许更多的东西一样：

Private Async Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click 
    Button1.Enabled = False 

    Await Task.Run(Sub() 

         ' ... do something ... 

         System.Threading.Thread.Sleep(3000) 
        End Sub) 

    Button1.Enabled = True 
End Sub
