什么是一个Windows服务和常规应用程序之间的区别？ [英] What is the difference between a windows service and a regular application?

问题描述

我只创建了普通的Windows应用程序（C＃居多）。有什么区别，从一个普通的Windows应用程序窗口服务？是什么让他们有什么不同？有什么可以服务做到这一点的应用程序不能？什么是从开发商看到的差异的观点？你如何创建？难道仅仅是创建一个普通的应用程序（控制台应用程序也许，由于没有鬼？），然后运行，或以特殊的方式安装，或者是更是有许多工作要做？

I have only created regular windows applications (C# mostly). What differentiates a windows service from a regular windows application? What makes them different? What can a service do that an application can't? What are the differences seen from a developers point of view? How do you create one? Is it just to create a regular application (Console application maybe, since there are no gui?) and run or install it in a special way, or is it more that has to be done?

推荐答案

有一对夫妇的事情，立即跳出了我。

There are a couple of things that jump out to me immediately.

• 它们运行在一个完全不同的控制台开始与Vista


• 作为在不同的控制台中运行的结果是，服务无法与桌面交互。所以基本上没有直接的UI支持。通常，您必须编写，它运行作为一个正常的程序，并使用了一些机制（命名管道为例）与该服务进行通信的兄弟UI应用程序。


• 通常只是你的服务的一个实例可以在任何给定时间运行。


• 流程是每个用户，服务是每个工作站，因此常常为多个用户提供服务。

• They run in an entirely different console starting with Vista
• As a result of running in a different console, services cannot interact with the desktop. So essentially there is no direct UI support. You typically have to code a sibling UI application that does run as a normal program and uses some mechanism (named pipes for example) to communicate with the service.
• Typically only one instance of your service can be running at any given time.
• Processes are per user, services are per work station and hence often provide services for multiple users.
