public:
 PrincipalPermission(System::String ^ name, System::String ^ role);

public PrincipalPermission (string name, string role);

new System.Security.Permissions.PrincipalPermission : string * string -> System.Security.Permissions.PrincipalPermission

Public Sub New (name As String, role As String)

Parameters

Examples

The following example requires the active principal to be an administrator. The name parameter is null, which enables any user who is an administrator to pass the demand.

Note In Windows Vista, User Account Control (UAC) determines the privileges of a user. If you are a member of the Built-in Administrators group, you are assigned two run-time access tokens: a standard user access token and an administrator access token. By default, you are in the standard user role. To execute the code that requires you to be an administrator, you must first elevate your privileges from standard user to administrator. You can do this when you start an application by right-clicking the application icon and indicating that you want to run as an administrator.

using namespace System;
using namespace System::Security;
using namespace System::Security::Permissions;

using namespace System::Security::Principal;

int main(array<System::String ^> ^args)

    System::String^ null;
    AppDomain::CurrentDomain->SetPrincipalPolicy(PrincipalPolicy::WindowsPrincipal);
    PrincipalPermission^ principalPerm = gcnew PrincipalPermission(null, "Administrators" );
      principalPerm->Demand();
      Console::WriteLine("Demand succeeded");
    return 0;
}

    public static void Main()
    {
        AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
        PrincipalPermission principalPerm = new PrincipalPermission(null, "Administrators");
        principalPerm.Demand();
        Console.WriteLine("Demand succeeded.");
    }
}

Class SecurityPrincipalDemo


    Public Shared Sub Main()
        AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal)
        Dim principalPerm As New PrincipalPermission(Nothing, "Administrators")
        principalPerm.Demand()
        Console.WriteLine("Demand succeeded.")

    End Sub
End Class

Remarks

Both the name parameter and the role parameter must match for this permission to match the active IPrincipal and associated IIdentity. Set name to null to check for any user in a role.
