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());
}
