Статия
07/22/2016

Applies To: Dynamics CRM 2015

This sample code is for Microsoft Dynamics CRM 2015 and Microsoft Dynamics CRM Online 2015 Update. Download the Microsoft Dynamics CRM SDK package. It can be found in the following location in the download package:

SDK\SampleCode\CS\GeneralProgramming\Authentication\ImpersonateWithOnBehalfOfPrivilege.cs

Requirements

For more information about the requirements for running the sample code provided in this SDK, see Use the sample and helper code.

The user (impersonator) must have the ActOnBehalfOf privilege or be a member of the PrivUserGroup group in Active Directory.

Demonstrates

This sample shows how to impersonate another user by setting the CallerId property of the organization web service proxy.

Examples

Code snippets that highlight the important code are shown first, followed by the Complete example code.

Code snippet


// Connect to the Organization service. 
// The using statement ensures that the service proxy will be properly disposed.
using (_serviceProxy = new OrganizationServiceProxy(serverConfig.OrganizationUri, serverConfig.HomeRealmUri,serverConfig.Credentials, serverConfig.DeviceCredentials))
{
    // This statement is required to enable early-bound type support.
    _serviceProxy.EnableProxyTypes();

    CreateRequiredRecords();

    // Retrieve the system user ID of the user to impersonate.
    OrganizationServiceContext orgContext = new OrganizationServiceContext(_serviceProxy);
    _userId = (from user in orgContext.CreateQuery<SystemUser>()
              where user.FullName == "Kevin Cook"
              select user.SystemUserId.Value).FirstOrDefault();

    // To impersonate another user, set the OrganizationServiceProxy.CallerId
    // property to the ID of the other user.
    _serviceProxy.CallerId = _userId;

    // Instantiate an account object.
    // See the Entity Metadata topic in the SDK documentation to determine 
    // which attributes must be set for each entity.
    Account account = new Account { Name = "Fourth Coffee" };

    // Create an account record named Fourth Coffee.
    _accountId = _serviceProxy.Create(account);
    Console.Write("{0} {1} created, ", account.LogicalName, account.Name);
