Not sure I fully understand the 'why', but as your question is phrased, if this as you have it returns a string
private string SendRequest(HttpWebRequest request, string queryParams, string token)
{
...
return someString;
}
then this
private HttpWebResponse SendRequest(HttpWebRequest request, string queryParams, string token)
{
HttpWebResponse response
...
return response;
}
does what you've asked for.... if that's not what you want, please modify your original question, please don't go posting your answers in the 'solutions'
