The following code example shows the behavior of the FromXml method. This example is part of a larger example provided for the ReflectionPermission class.

NoteNote

The code example is intended to show the behavior of the method, not to demonstrate its use. In general, the methods of permission classes are used by the security infrastructure; they are not typically used in applications.

private static void ToFromXmlDemo()
{
    ReflectionPermission memberAccessPerm = new ReflectionPermission(ReflectionPermissionFlag.MemberAccess);
    ReflectionPermission restrictedMemberAccessPerm = new ReflectionPermission(PermissionState.None);
    restrictedMemberAccessPerm.FromXml(memberAccessPerm.ToXml());
    Console.WriteLine("Result of ToFromXml = " +
        restrictedMemberAccessPerm.ToString());
}
