The ToXml method creates a SecurityElement instance to XML-encode a representation of the DnsPermission instance, including state information.

Use the FromXml method to restore the state information from a SecurityElement instance.

The following example creates an XML encoding of a DnsPermission instance.

public:
   void useDns()
   {
      // Create a DnsPermission instance.
      DnsPermission^ permission = gcnew DnsPermission( PermissionState::Unrestricted );

      // Check for permission.
      permission->Demand();
      // Create a SecurityElement Object* to hold XML encoding of the DnsPermission instance.
      SecurityElement^ securityElementObj = permission->ToXml();
      Console::WriteLine( "Tag, Attributes and Values of 'DnsPermission' instance :" );
      Console::WriteLine( "\n\tTag : {0}", securityElementObj->Tag );
      // Print the attributes and values.
      PrintKeysAndValues( securityElementObj->Attributes );
   }

private:
   void PrintKeysAndValues( Hashtable^ myList )
   {
      // Get the enumerator that can iterate through the hash table.
      IDictionaryEnumerator^ myEnumerator = myList->GetEnumerator();
      Console::WriteLine( "\n\t-KEY-\t-VALUE-" );
      while ( myEnumerator->MoveNext() )
      {
         Console::WriteLine( "\t {0}:\t {1}", myEnumerator->Key, myEnumerator->Value );
      }
      Console::WriteLine();
   }
