双击C＃中的Windows窗体

Question

如何检测哪个鼠标按钮双击表格，即左，右或中？

更新 我使用的是.NET2.0

Answer 1

查看MouseDoubleClick和MouseEventArgs以及MouseButtons Enumeration

MouseDoubleClick是Form事件之一。

Answer 2

将最后点击的按钮存储在 MouseUp 事件中，然后在双击事件中检查该按钮。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 3

在Whatever_Click或DoubleClick事件中，您可以查看MouseEventArgs e，其中包含按下的键。

 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

Answer 4

在form_MouseDoubleClick事件中，您可以追踪

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