将URL传递给查询字符串并从后面的c＃代码中读取

Question

I have html link which contain navigation URL like " https://mysiteURL.com/logout.aspx?ReturnUrl=https://www.yoursite.com/ "

Now functionality should be like when user click on above mention link it should redirect to logout page and then system will clear all session for user and redirect to “ReturnUrl “ value in our case it is https://www.yoursite.com .

Issue is when I try to read “ReturnUrl” from query sting it always return null value. My code behind is look like below.

if (Request["ReturnUrl"] != null && !string.IsNullOrEmpty(Request["ReturnUrl"]))
{
     Response.Redirect(Request["ReturnUrl"],true);
}

Can anyone give the solution this?

Answer 1

它看起来像你想要使用Request.QueryString["ReturnUrl"]而不是直接Request["ReturnUrl"] 。
