C# 最簡單的使程序單進程運行的方法

 

1.代碼1

static void Main()
        {
            Process current = Process.GetCurrentProcess();
            Process[] processes = Process.GetProcessesByName(current.ProcessName);
            foreach (Process process in processes)
            {
                if (process.Id != current.Id)
                {
                    if (process.MainModule.FileName == current.MainModule.FileName)
                    {
                        MessageBox.Show("程序已經運行", Application.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
                        return;
                    }
                }
            }
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }

2.代碼2

            Process current = Process.GetCurrentProcess();
            Process[] processes = Process.GetProcessesByName(current.ProcessName);
            foreach (Process process in processes)
            {
                if (process.Id != current.Id)
                {
                    if (process.MainModule.FileName == current.MainModule.FileName)
                    {
                        LogOperate.Error("===》當前進程已經啓動");
                        return;
                    }
                }
            }
