C＃动态添加事件处理程序 [英] C# dynamically add event handler

问题描述

您好，我有一个简单的问题。这里是我的代码：

Hi i have a simple question. here is my code:

        XmlDocument xmlData = new XmlDocument();
        xmlData.Load("xml.xml");

        /* Load announcements first */
        XmlNodeList announcements = xmlData.GetElementsByTagName("announcement");

        for (int i = 0; i < announcements.Count; i++)
        {
            ToolStripMenuItem item = new ToolStripMenuItem();

            item.Name = announcements[i].FirstChild.InnerText;
            item.Text = announcements[i].FirstChild.InnerText;

            /* HERE IS WERE I NEED HELP */

            item.Click += new EventHandler();

            this.freedomMenu.Items.AddRange(new System.Windows.Forms.ToolStripItem[] { item });
        }

xml LastChild保存每个信息的信息。我想创建一个单击事件处理程序，当单击列表项目时，一个消息框显示与其内的数据。我的问题是我不知道如何动态生成事件处理程序这样做：（

The xml LastChild holds information for each annoucement. I would like to create a click event handler where when teh list item is clicked, a message box shows up with the data inside it. My problem is i dont no how to dynamically generate event handlers to do this :(

推荐答案

try：

 /* HERE IS WERE I NEED HELP */

 item.Click += new EventHandler(toolStripClick);

实际处理程序：

void toolStripClick(object sender, EventArgs e)
{
     ToolStripItem item = (ToolStripItem)sender;
     MessageBox.Show(item.Text);
}
