string url = "www.example.aspx?name=AB&CD&id=1";

string query = url.Split('?')[1];

NameValueCollection nvc = HttpUtility.ParseQueryString(query);

int index = -1;

for(int i = 0; i < nvc.Count; i++)

{

if(nvc.AllKeys[i] == "name")

{

index = i;

break;

}

if (index > -1)

{

string name = nvc[index];

if (index < nvc.Count - 1)

{

for(int i = index + 1; i < nvc.Count; i++)

{

if (nvc.AllKeys[i] != null) break;

name += "&" + nvc[i];

}

Console.WriteLine("name = {0}", name);

}

else

{

Console.WriteLine("The key 'name' is not present in the querystring");

}

Console.ReadKey();
