When utilising the RestSharp RestClient method, an error occurs.

Forums .NETWhen utilising the RestSharp RestClient method, an error occurs.
Staff asked 2 years ago

My API uses RestSharp to call a REST API, and the code looks like this.

var testRequest = { My JSON Data}
var clientResponse = new RestClient(".....");
var callrequest = new RestRequest("....", Method.Post);
string authHeader = "...";

callrequest.AddParameter("application/json", testRequest, ParameterType.RequestBody);
callrequest.AddParameter("Authorization", "Bearer " + authHeader, ParameterType.HttpHeader);
var response = clientResponse.Execute(callrequest); <---- //Red line showing here
return Ok(response);


I’m unable to run my software because of the red line. Could someone perhaps explain what the problem is?

Thank you very much.

You are running the most recent RestSharp version. All sync methods have been deprecated since RestSharp utilizes HttpClient beneath the hood, and HttpClient has no sync overloads; everything is async.

Instead of ‘Execute’ use ‘ExecuteAsync’


Thank you Umang Ramani
