在global.asax中使用PreSendRequestHeaders事件

Question

我尝试在"Application_Start"方法中的global.asax文件中分配PreSendRequestHeaders事件.但这不起作用.

private void Application_Start()
{
    PreSendRequestHeaders += OnPreSendRequestHeaders;           
}

private void OnPreSendRequestHeaders(object sender, EventArgs e)
{
   // this is not called
}

没有调用OnPreSendRequestHeaders,为什么？是否可以在global.asax中分配PreSendRequestHeaders方法？

Answer 1

只需使用:

protected void Application_PreSendRequestHeaders(Object source, EventArgs e)
{

}

或者实例化处理程序:

protected void Application_Start()
{
    PreSendRequestHeaders += new EventHandler(OnPreSendRequestHeaders);
}

protected void OnPreSendRequestHeaders(object sender, EventArgs e)
{
    // should work now
}
