Most optimal way to parse querystring within a string in C#

Question

I have a querystring alike value set in a plain string. I started to split string to get value out but I started to wonder that I can proabably write this in one line instead. Could you please advice if there is more optimal way to do this?

I am trying to read "123" and "abc" like in Request.QueryString but from normal string.

 protected void Page_Load(object sender, EventArgs e) {     string qs = "id=123&xx=abc";     string[] urlInfo = qs.Split('&');     string id = urlInfo[urlInfo.Length - 2];     Response.Write(id.ToString());  } 

Answer 1

You can do it this way:

using System.Collections.Specialized;  NameValueCollection query = HttpUtility.ParseQueryString(queryString); Response.Write(query["id"]); 

Hope it helps.
