调用接口的代码！

public int SaveEk_student(ek_student ek_student)
        {
            RestClient client = new RestClient(“服务器地址”);
            RestRequest request = new RestRequest("Api/Unifease/ehaipf_users/EKStudent/EKStudent/SaveEk_student", HttpMethod.POST);
            request.RequestFormat = RequestDataFormat.Json;
            request.AddBody(ek_student);
            var response = client.ExecuteAsync<ReturnModel>(request);
            int code = Convert.ToInt32(response.Result.Data.Model);
            return code;
        }
