C# ToolStripMenuItem中的鼠标按钮

我有一个有几个项目的上下文菜单。其中一个项目有一个子菜单（或其他名称），其中包含一些项目（取决于找到的文件）

我想做的是，当我左键单击其中一个子项时，我希望一件事发生，当我右键单击时，我希望另一件事发生

我的问题是，当我使用FileToolStripMenuItem\u DropDownItemClicked时，参数中没有任何MouseeEventArgs，因此我无法找到用于单击项目的鼠标按钮

我尝试将其添加到参数中，但后来出现了一些错误

有人知道我怎么解决这个问题吗？因此，我可以找到单击子项（ToolStripMenuItem）时使用的鼠标按钮是什么

谢谢

编辑：以下是我用于创建子项的代码：

IPHostEntry ipE = Dns.GetHostEntry(Dns.GetHostName());
IPAddress[] IpA = ipE.AddressList;
for (int i = 0; i < IpA.Length; i++)
{
      if (!IpA[i].ToString().Contains(":"))
           cxItems.Items.Add(new ToolStripMenuItem(IpA[i].ToString()));
}

IPHostEntry ipE=Dns.GetHostEntry（Dns.GetHostName（））；
IPAddress[]IpA=ipE.AddressList；
对于（int i=0；i

对于这些项目，我希望能够根据我使用的鼠标按钮做不同的事情

 private void button2_Click(object sender, EventArgs e)
    {
        ToolStripMenuItem item1 = new ToolStripMenuItem("Menu1");
        ToolStripMenuItem subMenuitem1 = new ToolStripMenuItem("SubMenu");
        item1.DropDownItems.Add(subMenuitem1);
        this.contextMenuStrip1.Items.Add(item1);
        subMenuitem1.MouseDown += new MouseEventHandler(subMenuitem1_MouseDown);
        this.contextMenuStrip1.Show(this.button2,new Point(0,0));
    }

    void subMenuitem1_MouseDown(object sender, MouseEventArgs e)
    {
        //e.Button will determine which button was clicked.
        MessageBox.Show(e.Button.ToString());
    }

这应该有助于你开始

问题是，您只是说new ToolStripMenuItem（IpA[i].ToString（）），而没有保留对它的引用。以下是您需要如何做到这一点：

 IPHostEntry ipE = Dns.GetHostEntry(Dns.GetHostName());
    IPAddress[] IpA = ipE.AddressList;
    for (int i = 0; i < IpA.Length; i++)
    {
          if (!IpA[i].ToString().Contains(":"))
          {
               ToolStripMenuItem subItem = new ToolStripMenuItem(IpA[i].ToString());
               subItem.MouseDown += new MouseEventHandler(subItem_MouseDown);
               cxItems.Items.Add(subItem);
          }
    }

    void subMenuitem1_MouseDown(object sender, MouseEventArgs e)
    {
          //get a reference to the menu that was clicked
          ToolStripMenuItem clickedMenu = sender as ToolStripMenuItem;
          //e.Button will tell you which button was clicked.
    }

IPHostEntry ipE=Dns.GetHostEntry（Dns.GetHostName（））；
IPAddress[]IpA=ipE.AddressList；
对于（int i=0；i

您可以访问子菜单项吗？如果是这样，您可以处理子项上的MouseDown事件

private System.Windows.Forms.ToolStripMenuItem optionToolStripMenuItem;
private System.Windows.Forms.ToolStripMenuItem subitemToolStripMenuItem;
private System.Windows.Forms.ToolStripMenuItem subItem2ToolStripMenuItem;

public void init()
{
    // 
    // optionToolStripMenuItem
    // 
    this.optionToolStripMenuItem.DropDownItems.AddRange(new System.Windows.Forms.ToolStripItem[] {
    this.subitemToolStripMenuItem,
    this.subItem2ToolStripMenuItem});
    this.optionToolStripMenuItem.Name = "optionToolStripMenuItem";
    this.optionToolStripMenuItem.Size = new System.Drawing.Size(152, 22);
    this.optionToolStripMenuItem.Text = "Option";
    // 
    // subitemToolStripMenuItem
    // 
    this.subitemToolStripMenuItem.Name = "subitemToolStripMenuItem";
    this.subitemToolStripMenuItem.Size = new System.Drawing.Size(152, 22);
    this.subitemToolStripMenuItem.Text = "Subitem";
    // 
    // subItem2ToolStripMenuItem
    // 
    this.subItem2ToolStripMenuItem.Name = "subItem2ToolStripMenuItem";
    this.subItem2ToolStripMenuItem.Size = new System.Drawing.Size(152, 22);
    this.subItem2ToolStripMenuItem.Text = "SubItem2";
    this.subItem2ToolStripMenuItem.MouseDown += new System.Windows.Forms.MouseEventHandler(this.subItem2ToolStripMenuItem_MouseDown);
    this.subItem2ToolStripMenuItem.Click += new System.EventHandler(this.subItem2ToolStripMenuItem_Click);
}

private bool wasRightClicked = false;
private void subItem2ToolStripMenuItem_MouseDown(object sender, MouseEventArgs e)
{
    if (e.Button == MouseButtons.Right)
        wasRightClicked = true;
}

问题是，我在运行时创建子项，或者你称之为子项的任何东西。就像它搜索一些文件一样，如果找到它们，它会为每个文件创建一个项目。所以我真的不能像你的例子那样。发布你如何创建sbuitems的代码，我会看看我是否能帮上忙。编辑我的帖子。看看能不能帮上忙，谢谢！subItem.MouseClick只有一个小错误，但我改为subItem.MouseDown。但它现在起作用了，非常感谢！我把这篇文章标为正确答案。哎呀，我错了。我只是在回答中修正了它。很高兴它能为您工作。问题是我正在运行时创建子项，或者不管您怎么称呼它。就像它搜索一些文件一样，如果找到它们，它会为每个文件创建一个项目。所以我真的不能像你的例子那样。发布你如何创建sbuitems的代码，我会看看我是否能帮上忙。编辑我的帖子。看看能不能帮上忙，谢谢！subItem.MouseClick只有一个小错误，但我改为subItem.MouseDown。但它现在起作用了，非常感谢！我把这篇文章标为正确答案。哎呀，我错了。我只是在回答中修正了它。很高兴它对你有用。
