[C#]使用Mutex實現單一程式執行個體的注意事項

namespace WindowsFormsApplication10 { static class Program { /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false);

		Boolean bCreatedNew;

		//Create a new mutex using specific mutex name
		Mutex m = new Mutex(false, "myUniqueName", out bCreatedNew);

		if (bCreatedNew)
			Application.Run(new Form1());
	}
}

}

		//Create a new mutex using specific mutex name
		Mutex m = new Mutex(false, "myUniqueName", out bCreatedNew);

		GC.Collect();

		if (bCreatedNew)
			Application.Run(new Form1());
		...</pre>
