ASP.NET捕获并替换Global.asax中的输出 [英] ASP.NET Capture and replace output in Global.asax

问题描述

我需要替换从网站上每个页面发送的一些数据，我认为可以使用Global.asax来完成.到目前为止，这是我尝试过的:

I need to replace some data that's sent from every page on my site, and I think doing it with Global.asax. This is what I have tried with so far:

void Application_PreSendRequestContent(object sender, EventArgs e)
{
    System.IO.StreamReader sr = new System.IO.StreamReader(Response.OutputStream);
    String output = sr.ReadToEnd();

    Response.ClearContent();
    Response.Write("Testing..");
}

但这给了我一个ArgumentException.我究竟做错了什么?有什么更好的方法吗?

But this gives me an ArgumentException. What am I doing wrong? Is there any better way to do this?

谢谢
