C# 限制系统重开

 

  private bool IsRunning(string prcName)
        {       
            return (Process.GetProcessesByName(prcName).Length > 1) ? true : false;

        }

 

调用

   private void FrmMain_Load(object sender, EventArgs e)
        {
            if (IsRunning("CleanFileServer") == true)
            {
                MessageBox.Show("对不起,本系统已在运行!\n.", "提示", MessageBoxButtons.OK, MessageBoxIcon.Warning);
                this.Dispose();
                return;
            }
            else
            {
                ReadIp();
                StartListen();
            }
        }
