ImpersonationOption Enumeration
.NET Framework 3.0
Specifies the impersonation behavior for a service operation on a service instance.
Namespace: System.ServiceModel
Assembly: System.ServiceModel (in system.servicemodel.dll)
Assembly: System.ServiceModel (in system.servicemodel.dll)
| Member name | Description | |
|---|---|---|
| Allowed | Impersonation is performed if credentials are available and ImpersonateCallerForAllOperations is equal to true. | |
| NotAllowed | Impersonation is not performed. If ImpersonateCallerForAllOperations is equal to true, a validation exception occurs at service startup time. | |
| Required | Impersonation is required. |
The following code example on the service shows how to have a method impersonate the caller by using the OperationBehaviorAttribute to set the impersonation level.
[OperationBehavior(Impersonation = ImpersonationOption.Required)] public double Add(double n1, double n2) { double result = n1 + n2; Console.WriteLine("Received Add({0},{1})", n1, n2); Console.WriteLine("Return: {0}", result); DisplayIdentityInformation(); return result; }
