using System;

using System.Collections.Generic;

using System.Text;

using System.Drawing;

using System.Drawing.Printing;

using System.Security;

using System.Security.Permissions;


namespace ListPermissions

{

class Program

{

static void Main(string[] args)

{

UserPerm(new FileIOPermission(PermissionState.Unrestricted));

UserPerm(new EnvironmentPermission(EnvironmentPermissionAccess.Read, "USERNAME"));

UserPerm(new FileDialogPermission(FileDialogPermissionAccess.Open));

UserPerm(new IsolatedStorageFilePermission(PermissionState.Unrestricted));

UserPerm(new ReflectionPermission(ReflectionPermissionFlag.MemberAccess));

UserPerm(new UIPermission(UIPermissionWindow.SafeTopLevelWindows));

UserPerm(new PrintingPermission(PrintingPermissionLevel.SafePrinting));


Console.WriteLine("\nPress Enter key to continue");

Console.Read();

}


static private void UserPerm(CodeAccessPermission p)

{

// True or False depending on whether the user has the permission

Console.WriteLine(p.GetType().ToString() + ": " + SecurityManager.IsGranted(p));

}

}

}
