public class Example
{
public static void Main()
{
Console.WriteLine("ConsoleMonitor instance....");
ConsoleMonitor monitor = new ConsoleMonitor();
monitor.Write();
monitor.Dispose();
}
}輸出：
ConsoleMonitor instance.... The ConsoleMonitor class constructor. The Write method. The ConsoleMonitor finalizer. The Dispose(False) method. Disposing of unmanaged resources. If the monitor.Dispose method is called, the example displays the following output: ConsoleMonitor instance.... The ConsoleMonitor class constructor. The Write method. The Dispose method. The Dispose(True) method. Disposing of managed resources. Disposing of unmanaged resources.
