我是靠谱客的博主微笑诺言，最近开发中收集的这篇文章主要介绍C#检查单个实例，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

        public static Process RunningInstance()
        {
            Process currentProcess = Process.GetCurrentProcess();
            Process[] sameProcess = Process.GetProcessesByName(System.IO.Path.GetFileNameWithoutExtension(AppDomain.CurrentDomain.BaseDirectory + currentProcess.ProcessName));
            if (sameProcess != null && sameProcess.Length > 0)
            {
                // 遍历正在有相同名字运行的例程
                foreach (Process process in sameProcess)
                {
                    // 忽略现有的例程
                    if (process.Id != currentProcess.Id && (process.StartTime - currentProcess.StartTime).TotalMilliseconds <= 0)
                    {
                        process.Kill();
                        return null;
                        //return process;
                    }
                }
            }
            return null;
        }
