I want to call the google url shortner API from my C# Console Application, the request I try to implement is:

Answer 1

How about changing

   var requestContent = new FormUrlEncodedContent(new[] 
        {new KeyValuePair("longUrl", s),});

to

   var requestContent = new StringContent("{\"longUrl\": \" + s + \"}");
