範例

下列程式碼範例示範 如何使用 FromXml 方法。 此程式碼範例是提供給 類別之較大範例的 PermissionSet 一部分。

// Display result of ToXml and FromXml operations.
PermissionSet^ ps6 = gcnew PermissionSet( PermissionState::None );
ps6->FromXml( ps5->ToXml() );
Console::WriteLine( "Result of ToFromXml = {0}\n", ps6 );

// Display result of ToXml and FromXml operations.
PermissionSet ps6 = new PermissionSet(PermissionState.None);
ps6.FromXml(ps5.ToXml());
Console.WriteLine("Result of ToFromXml = " + ps6.ToString() + "\n");

' Display result of ToXml and FromXml operations.
Dim ps6 As New PermissionSet(PermissionState.None)
ps6.FromXml(ps5.ToXml())
Console.WriteLine("Result of ToFromXml = " & ps6.ToString() & ControlChars.Lf)
