Utilize HttpClient to generate a SSL access and generate REST access to fetch data

Webrequesthandler handler = new Webrequesthandler ();                Try                {                    X509Certificate2 certificate = new X509Certificate2 (System.IO.File.ReadAllBytes ( configurationmanager.appsettings["Webapicertpath"]), configurationmanager.appsettings["Webapicertpwd"]);;                    Handler. Clientcertificates.add (certificate);                    Servicepointmanager.servercertificatevalidationcallback =                        (object sender, X509Certificate certificate1, X509chain chain, sslpolicyerrors sslpolicyerrors) =                        {                            return true;                        };                }                Catch                {                }                httpClient = new HttpClient (handler);

To fetch data with REST httpclient, just utilize code below:

                Case "Get":                    result = Httpclient.getasync (URL). Result.Content.ReadAsStringAsync (). Result;                    break;                Case "POST":                    result = Httpclient.postasync (URL, content). Result.Content.ReadAsStringAsync (). Result;                    break;                Case "put":                    result = Httpclient.putasync (URL, content). Result.Content.ReadAsStringAsync (). Result;                    break;                Case "Delete":                    result = Httpclient.deleteasync (URL). Result.Content.ReadAsStringAsync (). Result;                    break;                Default: Break                    ;
