推荐答案

您应该使用互斥类，喜欢这里解释：Best办法在控制台应用程序C＃实现单？

You should use Mutex class, like explained here: Best way to implement singleton in a console application C#?

编辑：我在我的code：

class Program
{
    public const string AppName = "...";
    private static readonly Mutex mutex = new Mutex(true, Program.AppName);

    public Program()
    {
        if (!mutex.WaitOne(TimeSpan.Zero, true))
            throw new ApplicationException("Another instance already running");
    }
}
