如何使用RestSharp向Windows Phone 7发出POST请求？

Question

如何发送数据以验证服务器？使用当前代码：

 var client = new RestClient("http://myserver.com");

        var request = new RestRequest("login", Method.POST);
        request.AddParameter("email", "myemail", ParameterType.GetOrPost);
        request.AddParameter("pass", "mypassword", ParameterType.GetOrPost);
        request.AddParameter("token", "mytoken", ParameterType.GetOrPost);

        client.ExecuteAsync(request, (response) =>
        {
            var auth = response.Content.ToString();
        });

在此代码之后，如果程序嗅探器（HttpAnalyzer）查看Headers和Response Content，将在响应内容中写入：Request is not completed. waiting ...，响应标头将为空...如何发布帖子RestSharp？
