How to read the query string params of a ASP.NET raw URL?

问题

I have a variable

string rawURL = HttpContext.Current.Request.RawUrl;

How do I read the query string parameters for this url?

回答1:

This is probably what you're after

  Uri theRealURL = new Uri(HttpContext.Current.Request.Url.Scheme + "://" +   HttpContext.Current.Request.Url.Authority + HttpContext.Current.Request.RawUrl);

   string yourValue= HttpUtility.ParseQueryString(theRealURL.Query).Get("yourParm"); 

回答2:

No need to go through the RawUrl - the Request object already contains a parsed version, using the Request.QueryString property.

This is an indexed NameValueCollection.

回答3:

Try this:

string rawURL = HttpContext.Current.Request.ServerVariables["query_string"];

回答4:

There is Params property on Request object that will let you do it easily. You don't have to parse it yourself.

回答5:

This will solve your problem.....

string strReq = "";
strReq = HttpContext.Current.Request.RawUrl;
strReq = strReq.Substring(strReq.IndexOf('?') + 1);
