我在以前的文章中介绍过，在本文中我将介绍如何使用OrganizationServiceProxy类来连接CRM的Web Service。

 

Microsoft.Xrm.Sdk.Client.OrganizationServiceProxy类与 Microsoft.Xrm.Client.Services.OrganizationService类的区别在于，前者既然叫做Proxy，通常是在CRM的Context之外使用，而后者是在CRM的Context中使用的。另外一个区别是如果你想impersonate为其他人的话，就只能使用OrganizationServiceProxy（CallerId ）。

 

我在本文中创建一个console程序，通过OrganizationServiceProxy来使用CRM的Web Service，并通过设置OrganizationServiceProxy的CallerId 来代表别人创建一个 lead。顺便说一下，想要Impersonate别人的用户必须在CRM中具有Act on Behalf of Aonther User的权限，或者在Active Directory中加入PrivUserGroup。

 

using System; using Microsoft.Xrm.Sdk.Discovery; using Microsoft.Xrm.Sdk.Client; using System.Configuration; using Microsoft.Xrm.Sdk; using Microsoft.Crm.Sdk.Messages;namespace ConsoleApplication3 {     class Program     {         static void Main(string[] args)         {             string _discoveryServiceAddress = ConfigurationManager.AppSettings["DiscoveryServiceAddress"];             IServiceManagement
     
       serviceManagement = ServiceConfigurationFactory.CreateManagement
      
       (new Uri(_discoveryServiceAddress));             AuthenticationProviderType endpointType = serviceManagement.AuthenticationType;            AuthenticationCredentials authCredentials = GetCredentials(endpointType);            //String organizationUri = String.Empty;             //string organizationUniqueName = ConfigurationManager.AppSettings["OrganizationUniqueName"];             //// Get the discovery service proxy.             //using (DiscoveryServiceProxy discoveryProxy = GetProxy
       
        (serviceManagement, authCredentials))             //{             //    // Obtain organization information from the Discovery service.             //    if (discoveryProxy != null)             //    {             //        // Obtain information about the organizations that the system user belongs to.             //        OrganizationDetailCollection orgs = DiscoverOrganizations(discoveryProxy);             //        // Obtains the Web address (Uri) of the target organization.             //        organizationUri = FindOrganization(organizationUniqueName, orgs.ToArray()).Endpoints[EndpointType.OrganizationService];             //    }             //}            String organizationUri = ConfigurationManager.AppSettings["OrganizationServiceAddress"];             if (!String.IsNullOrWhiteSpace(organizationUri))             {                 IServiceManagement
        
          orgServiceManagement = ServiceConfigurationFactory.CreateManagement
         
          (new Uri(organizationUri));                // Set the credentials.                 AuthenticationCredentials credentials = GetCredentials(endpointType);                // Get the organization service proxy.                 using (OrganizationServiceProxy organizationProxy = GetProxy
          
           (orgServiceManagement, credentials)) { // This statement is required to enable early-bound type support. organizationProxy.EnableProxyTypes(); organizationProxy.CallerId = new Guid("D63C171E-F47C-E211-A79A-00155DA83B36"); // Now make an SDK call with the organization service proxy. // Display information about the logged on user. Guid userid = ((WhoAmIResponse)organizationProxy.Execute(new WhoAmIRequest())).UserId; Entity systemUser = organizationProxy.Retrieve("systemuser", userid, new Microsoft.Xrm.Sdk.Query.ColumnSet(new string[] { "firstname", "lastname" })); Entity newEntity = new Entity("lead"); newEntity["salutation"] = "test"; newEntity["middlename"] = "test"; ; newEntity["lastname"] = "test"; ; newEntity["jobtitle"] = "test"; ; organizationProxy.Create(newEntity); } } } private static AuthenticationCredentials GetCredentials(AuthenticationProviderType endpointType) { string _userName = ConfigurationManager.AppSettings["UserName"]; string _password = ConfigurationManager.AppSettings["Password"]; string _domain = ConfigurationManager.AppSettings["Domain"]; AuthenticationCredentials authCredentials = new AuthenticationCredentials(); switch (endpointType) { case AuthenticationProviderType.ActiveDirectory: authCredentials.ClientCredentials.Windows.ClientCredential = new System.Net.NetworkCredential(_userName, _password, _domain); break; case AuthenticationProviderType.Federation: case AuthenticationProviderType.OnlineFederation: authCredentials.ClientCredentials.UserName.UserName = _userName; authCredentials.ClientCredentials.UserName.Password = _password; break; default: break; } return authCredentials; } private static TProxy GetProxy
           
            (IServiceManagement
            
              serviceManagement, AuthenticationCredentials authCredentials) where TService : class where TProxy : ServiceProxy
             
               { Type classType = typeof(TProxy); if (serviceManagement.AuthenticationType != AuthenticationProviderType.ActiveDirectory) { AuthenticationCredentials tokenCredentials = serviceManagement.Authenticate(authCredentials); // Obtain discovery/organization service proxy for Federated, LiveId and OnlineFederated environments. // Instantiate a new class of type using the 2 parameter constructor of type IServiceManagement and SecurityTokenResponse. return (TProxy)classType .GetConstructor(new Type[] { typeof(IServiceManagement
              
               ), typeof(SecurityTokenResponse) }) .Invoke(new object[] { serviceManagement, tokenCredentials.SecurityTokenResponse }); } // Obtain discovery/organization service proxy for ActiveDirectory environment. // Instantiate a new class of type using the 2 parameter constructor of type IServiceManagement and ClientCredentials. return (TProxy)classType .GetConstructor(new Type[] { typeof(IServiceManagement
               
                ), typeof(System.ServiceModel.Description.ClientCredentials) }) .Invoke(new object[] { serviceManagement, authCredentials.ClientCredentials }); } private static OrganizationDetailCollection DiscoverOrganizations(IDiscoveryService service) { if (service == null) throw new ArgumentNullException("service"); RetrieveOrganizationsRequest orgRequest = new RetrieveOrganizationsRequest(); RetrieveOrganizationsResponse orgResponse = (RetrieveOrganizationsResponse)service.Execute(orgRequest); return orgResponse.Details; } private static OrganizationDetail FindOrganization(string orgUniqueName, OrganizationDetail[] orgDetails) { if (String.IsNullOrWhiteSpace(orgUniqueName)) throw new ArgumentNullException("orgUniqueName"); if (orgDetails == null) throw new ArgumentNullException("orgDetails"); OrganizationDetail orgDetail = null; foreach (OrganizationDetail detail in orgDetails) { if (String.Compare(detail.UniqueName, orgUniqueName, StringComparison.InvariantCultureIgnoreCase) == 0) { orgDetail = detail; break; } } return orgDetail; } } }
               
              
             
            
           
          
         
        
       
      
     

 

配置文件：

 

如果是使用On-Premise CRM，AuthenticationType 是ActiveDirectory；如果使用的是IFD On-Premise CRM，AuthenticationType 是Federation；如果是CRM Online，AuthenticationType 是OnlineFederation。

 

当使用IFD-CRM或者CRM Online的时候，不需要在configuration中填写domain，但username要使用UPN name，查看用户UPN name可以使用命令 whoami /upn

 

通过上面的代码创建的lead，你会发现createdby和modifiedby都是CallerId所指定的用户。

 

 

总结： 使用OrganizationServiceProxy类可以连接CRM的Web service。通过设置CallerId 可以Impersonate。
