推荐答案

的 的ContextMenuStrip 控件具有的 SourceControl 财产，将必须打开它的控制提供参考。你可以用它来提取控件中的文本：

The ContextMenuStrip control has a SourceControl property, that will have a reference to the control that opened it. You can use that to extract the text from the control:

private void MenuStripItem_Click(object sender, EventArgs e)
{
    ToolStripItem item = (sender as ToolStripItem);
    if (item != null)
    {
        ContextMenuStrip owner = item.Owner as ContextMenuStrip;
        if (owner != null)
        {
            MessageBox.Show(owner.SourceControl.Text);
        }
    }
}

。如果你不是一个的ContextMenuStrip 使用文本菜单，代码应该是这样的：

If you instead of a ContextMenuStrip use a ContextMenu, the code should look like this:

private void menuItem1_Click(object sender, EventArgs e)
{
    MenuItem item = (sender as MenuItem);
    if (item != null)
    {
        ContextMenu owner = item.Parent as ContextMenu;
        if (owner != null)
        {
            MessageBox.Show(owner.SourceControl.Text);
        }
    }
}
