RichTextBox class allows you to customize its behavior when user clicks the hyperlink. Add an event handler for the RichTextBox.LinkClicked event
RichTextBox 类允许您在用户单击超链接时自定义其行为。为RichTextBox.LinkClicked事件添加事件处理程序
Process p = new Process();
private void richTextBox1_LinkClicked(object sender, LinkClickedEventArgs e)
{
p = Process.Start("IExplore.exe", e.LinkText);
}

You should make sure that DetectUrlsis set to true. If that doesn't work on its own, you may need to add a handler for the LinkClickedevent.
您应该确保将DetectUrls其设置为true。如果这本身不起作用，您可能需要为该LinkClicked事件添加一个处理程序。

Make sure the text property includes a valid url. E.g. http://www.stackoverflow.com/
set the DetectUrlsproperty to true
Write an event handler for the LinkClickedevent.
确保 text 属性包含有效的 url。例如http://www.stackoverflow.com/
将DetectUrls属性设置为true
为LinkClicked事件编写一个事件处理程序。
Personally, I wouldn't pass "IExplore.exe"in as a parameter to the Process.Startcall as Microsoft advise as this presupposes that it is installed, and is the user's preferred browser. If you just pass the url to process start (as per below) then Windows will do the right thing and fire up the user's preferred browser with the appropriate url.
就个人而言，我不会像 Microsoft 建议的那样将“IExplore.exe”作为参数传递给Process.Start调用，因为这假定它已安装，并且是用户首选的浏览器。如果您只是将 url 传递给进程启动（如下所示），那么 Windows 将做正确的事情并使用适当的 url 启动用户的首选浏览器。
private void mRichTextBox_LinkClicked (object sender, LinkClickedEventArgs e) {
System.Diagnostics.Process.Start(e.LinkText);
}
