针对cURL请求的RestSharp POST请求

Question

我在.net中使用Restsharp作为web api客户端。我尝试了多种排列，但仍无法正常工作。它出现以下错误：

连接失败 系统返回： （13）许可被拒绝。

非常感谢任何帮助。

curl -v -H "Content-Type: application/json; charset=UTF-8" -X POST -d "{\"name\":\"ask question from mediator1\",\"title\":\"ask question from mediator\",\"abstractText\":\"ask question from mediator\",\"editorialService\":\"CHINA\",\"plcRef\":\"a-000-2000\"}"  http://mynetworkserver:8081/ask/asset

我正在使用的代码：

   RestClient client = new RestClient();
        client.BaseUrl = "http://mynetworkserver:8081/ask/asset"; // **Is this url correct?**
       RestRequest request = new RestRequest(Method.POST);
 var fQuestion = new FQuestion
            {
                name = "ask question from mediator 1",
                title = "ask question from mediator",
                abstractText = "ask question from mediator",
                editorialService = "CHINA",
                ref = "A-000-0023"
            };      
request.RequestFormat = DataFormat.Json;
        request.Resource = "asset"; **// What is this?**
        request.AddHeader("Content-Type", "application/json");
        request.AddBody(fQuestion);
        IRestResponse response = client.Execute(request);
