ImpersonationOption Enumeration

Specifies the impersonation behavior for a service operation on a service instance.

Namespace:  System.ServiceModel
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public enum ImpersonationOption

Member nameDescription
NotAllowedImpersonation is not performed. If ImpersonateCallerForAllOperations is equal to true, a validation exception occurs at service startup time.
AllowedImpersonation is performed if credentials are available and ImpersonateCallerForAllOperations is equal to true.
RequiredImpersonation is required.

Use the ImpersonationOption enumeration to control impersonation in applications.

This setting interacts with a configuration property on ImpersonateCallerForAllOperations in the following table.

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;
        }
