C# 进程终止通知

Question

我目前正在寻找一种在特定进程关闭时删除特定文件的方法。我找到了很多创建进程和为 exited 添加事件处理程序的示例，但我需要收到系统中所有进程的通知，而不仅仅是我创建的进程。

谁能阐明这是如何实现的？

我对你的问题很感兴趣，所以我为此写了一个小应用程序，希望你觉得它有用。可以在很多方面进行改进:)

class Program
{
    private static readonly List<Process> AllProcesses = new List<Process>();

    static void Main(string[] args)
    {
        var timer = new Timer(1000);
        timer.AutoReset = true;
        timer.Elapsed += (sender, eventArgs) =>
        {
            Process[] processSnapShot = Process.GetProcesses();
            var newProcesses = processSnapShot.Where(p => !AllProcesses.Select(p2 => p2.Id).Contains(p.Id));

            WireHandler(newProcesses);

            AllProcesses.AddRange(newProcesses);
        };

        var processes = Process.GetProcesses();
        WireHandler(processes);

        timer.Start();
        Console.ReadLine();
    }

    private static void WireHandler(IEnumerable<Process> processes)
    {
        foreach (var process in processes)
        {
            try
            {
                Console.WriteLine("Process started " + process.ProcessName);
                process.EnableRaisingEvents = true;
                process.Exited += ProcessOnExited;
            }
            catch (Exception e)
            {
                Console.WriteLine("Error occurred " + e.Message);
            }
        }
    }

    private static void ProcessOnExited(object sender, EventArgs eventArgs)
    {
        var process = (Process) sender;
        AllProcesses.Remove(process);

        Console.WriteLine("Process exited " + process.ProcessName);
    }
}
