双击到C＃中的Windows窗体＃

Question

如何检测，哪个鼠标按钮已双击形式，即左，右或中间？

更新时间： 我在form_MouseDoubleClick事件中使用.NET2.0

Answer 1

存放在的MouseUp事件最后点击的按钮，然后检查，在双击事件。示例代码：

MouseButtons _lastButtonUp = MouseButtons.None; 

private void Form1_MouseUp(object sender, MouseEventArgs e) 
{ 
    _lastButtonUp = e.Button; 
} 

private void Form1_DoubleClick(object sender, EventArgs e) 
{ 
    switch (_lastButtonUp) 
    { 
     case System.Windows.Forms.MouseButtons.Left: 
      MessageBox.Show("left double click"); 
      break; 
     case System.Windows.Forms.MouseButtons.Right: 
      MessageBox.Show("right double click"); 
      break; 
     case System.Windows.Forms.MouseButtons.Middle: 
      MessageBox.Show("middle double click"); 
      break; 
    } 

} 

Answer 2

你可以跟踪

void Form1_MouseDoubleClick(object sender, MouseEventArgs e) 
{ 
    if (e.Button == MouseButtons.Left) 
     { 
      // Do Operation 
     } 
}

看一看MouseDoubleClick和MouseEventArgs和MouseButtons Enumeration

MouseDoubleClick是一个表格事件。

Answer 4

在Whatever_Click或DoubleClick事件中，您可以检查MouseEventArgs e，它包含按下的按键。

private void Form1_MouseDoubleClick(object sender, MouseEventArgs e) 
{ 
    if (e.Button == MouseButtons.Left) 
     Console.WriteLine("Left Mouse Button was clicked!"); 
    else if (e.Button == MouseButtons.Middle) 
     Console.WriteLine("Middle Mouse Button was clicked!"); 
} 

其他按钮包括MouseButtons.Right，MouseButtons.Left
