检测 C# NET 中的应用程序关闭？

发布于 2024-10-13 02:59:11 字数 1506 浏览 4 评论 0原文

我正在编写一个小型控制台应用程序（将作为服务运行），它基本上在运行时启动 Java 应用程序，如果 Java 应用程序关闭则自行关闭，如果 Java 应用程序关闭则关闭 Java 应用程序。

我认为前两个工作正常，但我不知道如何检测 .NET 应用程序何时关闭，以便我可以在发生这种情况之前关闭 Java 应用程序。 Google 搜索仅返回一堆有关检测 Windows 关闭的信息。

谁能告诉我如何处理该部分以及其余部分是否看起来不错？

namespace MinecraftDaemon
{
    class Program
    {
        public static void LaunchMinecraft(String file, String memoryValue)
        {
            String memParams = "-Xmx" + memoryValue + "M" + " -Xms" + memoryValue + "M ";
            String args = memParams + "-jar " + file + " nogui";
            ProcessStartInfo processInfo = new ProcessStartInfo("java.exe", args);
            processInfo.CreateNoWindow = true;
            processInfo.UseShellExecute = false;

            try
            {
                using (Process minecraftProcess = Process.Start(processInfo))
                {
                    minecraftProcess.WaitForExit();
                }
            }
            catch
            {
                // Log Error
            }
        }

        static void Main(string[] args)
        {
            Arguments CommandLine = new Arguments(args);

            if (CommandLine["file"] != null && CommandLine["memory"] != null)
            {
                // Launch the Application
                LaunchMinecraft(CommandLine["file"], CommandLine["memory"]);
            }
            else
            {
                LaunchMinecraft("minecraft_server.jar", "1024");
            }
        }
    }
}

I am writing a small console application (will be ran as a service) that basically starts a Java app when it is running, shuts itself down if the Java app closes, and shuts down the Java app if it closes.

I think I have the first two working properly, but I don't know how to detect when the .NET application is shutting down so that I can shutdown the Java app prior to that happening. Google search just returns a bunch of stuff about detecting Windows shutting down.

Can anyone tell me how I can handle that part and if the rest looks fine?

namespace MinecraftDaemon
{
    class Program
    {
        public static void LaunchMinecraft(String file, String memoryValue)
        {
            String memParams = "-Xmx" + memoryValue + "M" + " -Xms" + memoryValue + "M ";
            String args = memParams + "-jar " + file + " nogui";
            ProcessStartInfo processInfo = new ProcessStartInfo("java.exe", args);
            processInfo.CreateNoWindow = true;
            processInfo.UseShellExecute = false;

            try
            {
                using (Process minecraftProcess = Process.Start(processInfo))
                {
                    minecraftProcess.WaitForExit();
                }
            }
            catch
            {
                // Log Error
            }
        }

        static void Main(string[] args)
        {
            Arguments CommandLine = new Arguments(args);

            if (CommandLine["file"] != null && CommandLine["memory"] != null)
            {
                // Launch the Application
                LaunchMinecraft(CommandLine["file"], CommandLine["memory"]);
            }
            else
            {
                LaunchMinecraft("minecraft_server.jar", "1024");
            }
        }
    }
}

您需要在 Main 方法中注册此事件：

Application.ApplicationExit += new EventHandler(AppEvents.OnApplicationExit);

并添加事件处理程序

public void OnApplicationExit(object sender, EventArgs e)
{
    try
    {
        Console.WriteLine("The application is shutting down.");
    }
    catch(NotSupportedException)
    {
    }
}

You will need to register this event in your Main method:

Application.ApplicationExit += new EventHandler(AppEvents.OnApplicationExit);

and add the event handler

public void OnApplicationExit(object sender, EventArgs e)
{
    try
    {
        Console.WriteLine("The application is shutting down.");
    }
    catch(NotSupportedException)
    {
    }
}

啊 MineCraft :)

由于您的控制台应用程序最终将成为 Windows 服务，请查看 OnStop、OnPowerEvent、onPause 和 onShutDown 方法msdn.microsoft.com/en-us/library/5xh5cfw0.aspx" rel="nofollow">ServiceBase 类。
