The FromXml method reconstructs a DataProtectionPermission object from an XML encoding defined by the SecurityElement class. Use the ToXml method to XML-encode the DataProtectionPermission, including state information.

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

System_CAPS_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.

Console.WriteLine("Using an XML round trip to reset the fourth " +
    "permission.");
sp4.FromXml(sp2.ToXml());
rc = sp4.Equals(sp2);
Console.WriteLine("Does the XML round trip result equal the " +
    "original permission? " + (rc ? "Yes" : "No"));
