CRM 2011 Dicovery服務FaultException

Question

我在http://social.microsoft.com/Forums/en-US/crmdevelopment/thread/d5d00302-8f7b-4efc-873b-c54b3e29749d問了同樣的問題，但沒有得到答案。所以，我會再次嘗試在stackoverflow。

我正在運行crm 2011培訓工具包中的示例代碼。

var creds = new ClientCredentials(); 
var dsp = new DiscoveryServiceProxy(dinfo, creds); 
dsp.Authenticate(); 
var orgRequest = new RetrieveOrganizationRequest(); 
var response = dsp.Execute(orgRequest); 
var orgResponse = response as RetrieveOrganizationsResponse; 
if (orgResponse != null) 
comboOrgs.ItemsSource = orgResponse.Details; 

在VAR響應線= dsp.Execute（orgRequest），我得到了FaltException`1，詳細信息如下

System.ServiceModel.FaultException`1 was unhandled 
Message=organizationName

我能夠訪問Discovery.svc文件使用瀏覽器。所以服務器網址應該是正確的。這是一個身份驗證問題嗎？

Answer 1

這是用於Microsoft CRM Online還是內部部署？對於網絡，我知道你想什麼在SDK中使用的東西線沿線的 -

// Connect to the Discovery service. 
// The using statement assures that the service proxy will be properly disposed. 
using (DiscoveryServiceProxy _serviceProxy = new DiscoveryServiceProxy(serverConfig.DiscoveryUri, 
                serverConfig.HomeRealmUri, 
                serverConfig.Credentials, 
                serverConfig.DeviceCredentials)) 
{ 
    // You can choose to use the interface instead of the proxy. 
    IDiscoveryService service = _serviceProxy; 

    #region RetrieveOrganizations Message 

    // Retrieve details about all organizations discoverable via the 
    // Discovery service. 
    RetrieveOrganizationsRequest orgsRequest = 
     new RetrieveOrganizationsRequest() 
     { 
      AccessType = EndpointAccessType.Default, 
      Release = OrganizationRelease.Current 
     }; 
    RetrieveOrganizationsResponse organizations = 
     (RetrieveOrganizationsResponse)service.Execute(orgsRequest); 
} 

有對DiscoveryServiceProxy類重載，但如果你提供你要連接什麼一些更多的細節到，我想它會縮小它的範圍。
