为什么ReleaseMutex不会释放锁？解决方案

为什么ReleaseMutex不会释放锁？
我仅仅是想测试一下Mutex类的用法,代码如下:

C# code

static class Program    {        /// <summary>        /// The main entry point for the application.        /// </summary>        [STAThread]        static void Main()        {            try            {                const string mutextName = "wwwwwwwwhhhwlllllll77777777ll9999llllwwww";                Mutex m = new Mutex(true, mutextName);                bool b = m.WaitOne(TimeSpan.Zero, true);                MessageBox.Show(b.ToString());                                m.ReleaseMutex();                                Application.EnableVisualStyles();                Application.SetCompatibleTextRenderingDefault(false);                Application.Run(new Form1());            }            catch (Exception e)            {                MessageBox.Show(e.Message);            }        }    }

C# code

Mutex m = new Mutex(true, mutextName);
