删除单击鼠标中键的选项卡的最短代码是使用LINQ。

确保事件已连线
this.tabControl1.MouseClick += tabControl1_MouseClick;
而对于处理程序本身
private void tabControl1_MouseClick(object sender, MouseEventArgs e)
{
  var tabControl = sender as TabControl;
  var tabs = tabControl.TabPages;

  if (e.Button == MouseButtons.Middle)
  {
    tabs.Remove(tabs.Cast<TabPage>()
            .Where((t, i) => tabControl.GetTabRect(i).Contains(e.Location))
            .First());
  }
}
如果你正在争取最少量的线路,这里就是一行
tabControl1.MouseClick += delegate(object sender, MouseEventArgs e) { var tabControl = sender as TabControl; var tabs = tabControl.TabPages; if (e.Button == MouseButtons.Middle) { tabs.Remove(tabs.Cast<TabPage>().Where((t, i) => tabControl.GetTabRect(i).Contains(e.Location)).First()); } };

没有LINQ的解决方案不那么紧凑和漂亮,但也是实际的:

private void TabControlMainMouseDown(object sender, MouseEventArgs e)
{
    var tabControl = sender as TabControl;
    TabPage tabPageCurrent = null;
    if (e.Button == MouseButtons.Middle)
    {
        for (var i = 0; i < tabControl.TabCount; i++)
        {
            if (!tabControl.GetTabRect(i).Contains(e.Location))
                continue;
            tabPageCurrent = tabControl.TabPages[i];
            break;
        }
        if (tabPageCurrent != null)
            tabControl.TabPages.Remove(tabPageCurrent);
    }
}

没有足够的积分向所提供的解决方案发布评论,但它们都有相同的缺陷:删除的标签中的控件不会被释放。

此致

你可以这样做:

private void tabControl1_MouseClick(object sender, MouseEventArgs e)
{
     if (e.Button == MouseButtons.Middle)
     {
          // choose tabpage to delete like below
          tabControl1.TabPages.Remove(tabControl1.TabPages[0]);
     }
}

基本上,您只需在选项卡控件上单击鼠标,仅在单击中间按钮时删除页面。
