我有很多Azure管理API使用下面的代码,除了GetRole for Virtual Machines.这是api调用的文档:https://msdn.microsoft.com/en-us/library/azure/jj157193.aspx

这是我试图执行的代码:

static void Main(string[] args)
        {
            Program p = new Program();
            p.MakeRequest();
        }

        public void MakeRequest()
        {
            string strThumbprint = "{thumbprint}";
            X509Certificate2 certificate = GetStoreCertificate(strThumbprint);
            string strRequestURI = "https://management.core.windows.net/{subscription}/services/hostedservices/{cloud-service}/deployments/{deployment}/roles/{rolename}";
            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(strRequestURI);
            request.ClientCertificates.Add(certificate);
            request.ContentType = "application/xml";
            request.Headers.Add("x-ms-version", "2015-04-01");
            try
            { 
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Console.WriteLine("Status Code: " + response.StatusCode.ToString());
            Stream receiveStream = response.GetResponseStream();
            Encoding encode = Encoding.GetEncoding("utf-8");
            StreamReader readStream = new StreamReader(receiveStream, encode);
            Console.WriteLine(readStream.ReadToEnd());
            response.Close();
            }
            catch(Exception ex)
            {
                Console.WriteLine("Error: " + …

谁能告诉我在 c# 中检查对象或对象的属性是否为空的性能成本是多少？我正在开发一个 ASP.NET MVC 应用程序，该应用程序正在模型中完成空检查，然后在视图中再次完成。我觉得这太过分了，但如果没有真正的性能下降，那么我不认为这样做有什么害处。
