CRM 2016 api無許可アクセス

Question

私はCRM on premise 2016に接続してデータを取得するためにこのコードを書いています。

ここでは、

var credentials = new NetworkCredential("username", "password?", "domain"); 
      var client = new HttpClient(new HttpClientHandler() { Credentials = credentials }) 
      { 
       BaseAddress = new Uri("https://xxxtestenv.elluciancrmrecruit.com/api/data/v8.0/") 
      }; 
      client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 
      var response = client.GetAsync("datatel_events?$orderby=datatel_eventname").Result; 
      if (response.IsSuccessStatusCode) 
      { 
       var yourcustomobjects = response.Content.ReadAsStringAsync(); 
      } 

だが、私は

response {StatusCode: 401, ReasonPhrase: 'Unauthorized', Version: 1.1, Content: System.Net.Http.StreamContent, Headers: 

{ REQ_IDこのエラーが出る：b685b007-199b-4a4a-85cc-3a29684e5588 日：木、2016年9月22日19： 27:35 GMT サーバー：マイクロソフト-IIS/8.5 WWW認証：ネゴシエート WWW認証：NTLM X -Poweredバイ：ASP.NET 接続：キープアライブ のContent-Length：49 のContent-Type：text/plainの }} System.Net.Http.HttpResponseMessage

任意の提案ですか？

以下のコードを使用して、前提条件のMS CRMに接続してみてください。

string strOrganizationUri = "https://{your domain}/XRMServices/2011/Organization.svc"; 
      string strUserName = "{your domain username}"; 
      string strPassword = "{your domain password}"; 
      var organizationUriIFD = new Uri(strOrganizationUri); 

      var credentials = new ClientCredentials(); 
      credentials.UserName.UserName = strUserName; 
      credentials.UserName.Password = strPassword; 

      IServiceConfiguration<IOrganizationService> config = ServiceConfigurationFactory.CreateConfiguration<IOrganizationService>(organizationUriIFD); 
      IOrganizationService service; 
      using (var serviceProxy = new OrganizationServiceProxy(config, credentials)) 
      { 
       // This statement is required to enable early-bound type support. 
       serviceProxy.ServiceConfiguration.CurrentServiceEndpoint.Behaviors.Add(new ProxyTypesBehavior()); 

       service = serviceProxy; 

      } 


      // Get the ID's of the current user and business unit. 
      var who = new WhoAmIRequest(); 
      //retreive user data from the server. 
      var whoResponse = (WhoAmIResponse)service.Execute(who);
