Specifies the impersonation behavior for a service operation on a service instance.
public enum class ImpersonationOption
public enum ImpersonationOption
type ImpersonationOption =
Public Enum ImpersonationOption
- Inheritance
Fields
Name | Value | Description |
---|---|---|
NotAllowed | 0 | Impersonation is not performed. If ImpersonateCallerForAllOperations is equal to |
Allowed | 1 | Impersonation is performed if credentials are available and ImpersonateCallerForAllOperations is equal to |
Required | 2 | Impersonation is required. |
Examples
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;
}
<OperationBehavior(Impersonation := ImpersonationOption.Required)> _
Public Function Add(ByVal n1 As Double, ByVal n2 As Double) As Double Implements ICalculator.Add
Dim result = n1 + n2
Console.WriteLine("Received Add({0},{1})", n1, n2)
Console.WriteLine("Return: {0}", result)
DisplayIdentityInformation()
Return result
End Function
Remarks
Use the ImpersonationOption enumeration to control impersonation in Windows Communication Foundation (WCF) applications.
This setting interacts with a configuration property on ImpersonateCallerForAllOperations in the following table.
