声明
Public NotInheritable Class CallerImpersonationScope
    Implements IDisposable

public sealed class CallerImpersonationScope : IDisposable

备注

The specified user does not have to be the same user that instantiated the service. When the CallerImpersonationScope object goes out of scope and is disposed, calls to the service are owned by the original user that instantiated the service.

using (new CallerImpersonationScope(service, userId))
{
   // Display information about the logged on user.
   Guid effectiveUserId = ((WhoAmIResponse)service.Execute(new WhoAmIRequest())).UserId;
   SystemUser systemUser = (SystemUser)service.Retrieve("systemuser", effectiveUserId, 
       new ColumnSet(new string[] {"firstname", "lastname"}));
   Console.WriteLine("Logged on user is {0} {1}.", systemUser.FirstName, systemUser.LastName);
}
