使用鼠標中鍵關閉winforms選項卡控件上的選項卡

Question

有沒有簡單的（5行代碼）方法來做到這一點？

Answer 1

刪除單擊鼠標中鍵的選項卡的最短代碼是使用LINQ。

確保事件已連線

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()); } };

而對於處理程序本身

 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()); } } 

如果你正在爭取最少量的線路，這里就是一行

 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()); } }; 

Answer 2

沒有LINQ的解決方案不那么緊湊和美觀，而且實際：

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);
    }
}

Answer 3

沒有足夠的積分向提供的解決方案發布評論，但它們都有相同的缺陷：刪除的標簽中的控件不會被釋放。

問候

Answer 4

你可以這樣做：

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，您只需在選項卡控件上單擊鼠標，僅在單擊中間按鈕時刪除頁面。
