使用内核对象Mutex可以防止同一个进程运行两次

用互斥法实现防止程序重复运行，使用内核对象Mutex可以防止同一个进程运行两次。注意：是名称相同的进程，而不是exe，因为exe程序可以改名。

在Program.cs中修改

首先添加using System.Threading;引用

然后原内容改为下面所示

    static class Program
    {
        private static Mutex myMutex;
        private static bool requestInitialOwnership = true;
        private static bool mutexWasCreated;
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            //原来代码
            //Application.EnableVisualStyles();
            //Application.SetCompatibleTextRenderingDefault(false);
            //Application.Run(new Form1());

            //新代码
            myMutex = new Mutex(requestInitialOwnership, "CanbeAnything ", out mutexWasCreated);
            if (mutexWasCreated)
            {
                Application.Run(new Form1());
                myMutex.WaitOne();
            }
        }
    }
