C# WinForm 多个单击事件处理程序用于类似功能 [英] C# WinForm multiple click event handlers for similar function

问题描述

我有一些 toolStripMenuItems 作为一系列网站的有用链接，代码的粗略示例如下:

I have a few toolStripMenuItems that act as a useful links for a series of websites, a rough example of the code would be something like:

private void toolStripMenuItem1_Click(object sender, EventArgs e)
{
    Process.Start("http://www.google.com");
}

private void toolStripMenuItem2_Click(object sender, EventArgs e)
{
    Process.Start("http://www.bing.com");
}

private void toolStripMenuItem3_Click(object sender, EventArgs e)
{
    Process.Start("https://www.duckduckgo.com");
}

private void toolStripMenuItem4_Click(object sender, EventArgs e)
{
    Process.Start("http://www.yahoo.com/");
}
...

有没有更优雅的方法来处理这个问题?

Is there a more elegant way to handle this?

推荐答案

要做的第一件事是对每个处理程序使用相同的处理程序:

The first thing to do is use the same handler for each one:

toolStripMenu1.Click += toolStripItemClick;
toolStripMenu2.Click += toolStripItemClick;
// etc

我会为此使用 Tag 属性，在构建 toolStripItems 时设置它:

I would use the Tag property for this, set it when you're constructing the toolStripItems:

toolStripMenu1.Tag = "http://www.google.com";

然后定义您的处理程序:

And then define your handler:

private void toolStripItemClick(object sender, EventArgs e)
{
    var c = (ToolStripMenuItem)sender;
    Process.Start(c.Tag.ToString());
}
