Examples

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

Note

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.
