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

// ToXml creates an XML encoding of the permission and its current state; FromXml 
// reconstructs a permission with the specified state from the XML encoding. 
private static bool ToFromXmlDemo()
{

    bool returnValue = true;
    readPerm2 = new RegistryPermission(PermissionState.None);
    readPerm2.FromXml(readPerm1.ToXml());
    Console.WriteLine("Result of ToFromXml = " + readPerm2.ToString() + "\n");
    return returnValue;

}
