方法1：using System;using System.Collections.Generic;using System.Linq;using System.Windows.Forms;using System.Diagnostics;namespace MonitorHardDisk{    static class Program    {        private static System.Threading.Mutex mutex;        /// <summary>        /// 应用程序的主入口点。        /// </summary>        [STAThread]        static void Main()        {            Application.EnableVisualStyles();            Application.SetCompatibleTextRenderingDefault(false);            mutex = new System.Threading.Mutex(true, "OnlyRun");            if (mutex.WaitOne(0, false))            {                Application.Run(new Form1());            }            else            {                MessageBox.Show("程序已经在运行！", "系统提示", MessageBoxButtons.OK, MessageBoxIcon.Warning);                Application.Exit();            }        }    }}方法2：            #region 禁止多进程启动控制            bool b;            Mutex m = new Mutex(true, "PharmeyesDDIWinUIThreadCs", out b);            int i = 0;            foreach (System.Diagnostics.Process p in System.Diagnostics.Process.GetProcesses())            {                if ("Pharmeyes.DDI.WinUI".ToLower().Equals(p.ProcessName.ToString().ToLower()))                {                    i++;                }            }            if (!b || i > 1)            {                log.Info(string.Format("程序在系统进程中已存在！...................................."));                return;            }            #endregion
