使控制台应用程序的行为类似于Windows应用程序 [英] Making a console application behave like a Windows application

问题描述

我有一个控制台应用程序，我希望它能够等待直到引发某些事件.但是它执行代码并退出:

I have a console application, and I want it to wait till some event is raised. But it executes the code and exits:

static void Main(string[] args)
{
    var someObjectInstance = new SomeObject();
    someObjectInstance.SomeEvent += SomeEventHandler;
}

static void SomeEventHandler()
{
    //Some logic
}

我想让我的应用程序像Windows应用程序一样运行

I want to make my application behave like a Windows application where

Application.Run(new Form1());

被调用并运行消息循环.

is called and the message loop is run.

但是我既不需要消息循环也不需要任何形式.所以看起来像是开销.有没有更轻巧的方法可以实现我的目标?

But I don't need neither a message loop nor any form. So it looks like overhead. Is there a more light-weight way to achieve my goal?

推荐答案

首先，除非 SomeObject 打算在单独的线程上引发事件，否则，如果不进行某种形式的处理，这将无法正常工作在 SomeObject 中.但是，如果采用这种方式设计，那将非常简单.

First off, unless SomeObject is going to raise the event on a separate thread, this won't work without some form of processing in SomeObject. If it's designed that way, however, this is fairly straightforward.

一种非常有效的处理方法是等待WaitHandle:

A very efficient way of handling this is to just wait on a WaitHandle:

private static ManualResetEvent waitHandle = new ManualResetEvent(false);
static void Main(string[] args)
{
    var someObjectInstance = new SomeObject();
    someObjectInstance.SomeEvent += SomeEventHandler;
    waitHandle.WaitOne(); // Will block until event occurs
}

static void SomeEventHandler()
{
    //some logic
    waitHandle.Set(); // Will allow Main() to continue, exiting the program
}
