WebAPI- Query String Value from HttpRequest Url

In Web Api, always need to get query string value with the specified query string name from httprequest.

namespace QueryStringExtension
{
 
 public static class StringExtension
 {
        public static string GetSQueryString(this HttpRequestMessage request, string key)
        {
 
         var queryStrings = request.GetQueryNameValuePairs();
         if (queryStrings == null)
                return null;
 
         var match = queryStrings.FirstOrDefault(kv => string.Compare(kv.Key, key, true) == 0);
         if (string.IsNullOrEmpty(match.Value))
                return null;
 
         return match.Value;
        }
 
 }
}
