The best solution for me is      Add key value var dict   new Dictionary lt string  string gt     dict Add  Content-Type    application x-www-form-urlencoded        Execute post method using  var response   httpClient PostAsync path  new FormUrlEncodedContent dict

Another variant to POST this content type and which does not use a dictionary would be  StringContent postData   new StringContent JSON CONTENT  Encoding UTF8   quot application x-www-form-urlencoded quot    using  HttpResponseMessage result   httpClient PostAsync url  postData  Result        string resultJson   result Content ReadAsStringAsync   Result
