实现

示例

下面的代码示例在另一个按钮的Button交替Click事件上生成 一个 Click 事件。 此代码假定已在窗体上实例化了两 Button 个控件,并且名为 myVar 的成员变量已在 类中声明为 32 位有符号整数。

private:
   void button1_Click( Object^ /*sender*/, EventArgs^ /*e*/ )
   {
      // If myVar is an even number, click Button2.
      if ( myVar % 2 == 0 )
      {
         button2->PerformClick();
         // Display the status of Button2's Click event.
         MessageBox::Show( "button2 was clicked " );
      }
      else
      {
         // Display the status of Button2's Click event.
         MessageBox::Show( "button2 was NOT clicked" );
      }
      // Increment myVar.   
      myVar++;
   }
private void button1_Click (Object sender, 
                               EventArgs e)
 {
    // If myVar is an even number, click Button2.
    if(myVar %2 == 0)
    {
       button2.PerformClick();
       // Display the status of Button2's Click event.
       MessageBox.Show("button2 was clicked ");
    }
    else
    {
       // Display the status of Button2's Click event.
       MessageBox.Show("button2 was NOT clicked");
    }
    // Increment myVar.   
    myVar = myVar + 1;
 }
Private Sub button1_Click(sender As Object, e As EventArgs)
    ' If myVar is an even number, click Button2.
    If myVar Mod 2 = 0 Then
        button2.PerformClick()
        ' Display the status of Button2's Click event.
        MessageBox.Show("button2 was clicked ")
    Else
        ' Display the status of Button2's Click event.
        MessageBox.Show("button2 was NOT clicked")
    End If
    ' Increment myVar.   
    myVar = myVar + 1
End Sub
