如何确保在C#中只有一个程序(实例)运行?
解答:主要应用System.Diagnostics名字空间中的Process类来实现,思路,我们在运行程序前,查找进程中是否有同名的进程,同时运行位置也相同程,如是没有运行该程序,如果有,就将同名的同位置的程序窗口置前. 主要代码:
[C#] public static Process RunningInstance() { Process current = Process.GetCurrentProcess(); Process[] processes = Process.GetProcessesByName (current.ProcessName); //查找相同名称的进程 foreach (Process process in processes) { //忽略当前进程 if (process.Id != current.Id) { //确认相同进程的程序运行位置是否一样. if (Assembly.GetExecutingAssembly().Location.Replace("/", "\\") == current.MainModule.FileName) { //Return the other process instance. return process; } } } //No other instance was found, return null. return null; }
