创建一个组合命令行/ Windows服务的应用程序 [英] Create a combo command line / Windows service app

问题描述

什么是在C＃中的最佳方式来建立一个实用的应用程序，可以通过命令行运行并产生一些输出（或写入文件），但可能是运行作为Windows服务，以及完成其工作在后台（如监控目录，或其他）。

What's the best way in C# to set up a utility app that can be run from the command line and produce some output (or write to a file), but that could be run as a Windows service as well to do its job in the background (e.g. monitoring a directory, or whatever).

我想写出code一次，可以任意调用它交互的PowerShell的或其他的CLI，但同时也找到一种方法来安装相同的EXE文件作为Windows服务，并有它自动运行。

I would like to write the code once and be able to either call it interactively from PowerShell or some other CLI, but at the same time also find a way to install the same EXE file as a Windows service and have it run unattended.

我能做到这一点？如果是的话：我怎么能做到这一点。

Can I do this? And if so: how can I do this?

推荐答案

当然可以。

要做到这一点是使用命令行参数的一种方法，说/控制台，告诉除了作为服务运行版的控制台版本：

One way to do it would be to use a command line param, say "/console", to tell the console version apart from the run as a service version:

• 创建一个Windows控制台应用程序，然后
• 在Program.cs中，更多的precisely的主要功能，你可以测试/控制台的presence参数
• 如果在/控制台是存在的，正常启动程序
• 如果该参数是不存在的，从ServiceBase的调用服务类

// Class that represents the Service version of your app
public class serviceSample : ServiceBase
{
    protected override void OnStart(string[] args)
    {
        // Run the service version here 
        //  NOTE: If you're task is long running as is with most 
        //  services you should be invoking it on Worker Thread 
        //  !!! don't take too long in this function !!!
        base.OnStart(args);
    }
    protected override void OnStop()
    {
        // stop service code goes here
        base.OnStop();
    }
}

...

然后在Program.cs的：

Then in Program.cs:

static class Program
{
    // The main entry point for the application.
    static void Main(string[] args)
    {
        ServiceBase[] ServicesToRun;

    if ((args.Length > 0) && (args[0] == "/console"))
    {
        // Run the console version here
    }
    else
    {
        ServicesToRun = new ServiceBase[] { new serviceSample () };
        ServiceBase.Run(ServicesToRun);
    }
}

}
