在控制台模式下运行 Windows 服务? [英] Running a Windows Service in Console mode?
本文介绍了在控制台模式下运行 Windows 服务?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我发现一些示例代码发布在https://groups.google.com/group/microsoft.public.dotnet.languages.csharp/browse_thread/thread/4d45e9ea5471cba4/4519371a77ed4a74?hl=en&pli=1用于自行安装 Windows 服务.我在 fx 4.0 上使用 C#.试找出我在哪里出轨...
我的问题:
- 我创建了一个 Win Service 项目.在 program.cs/main() 我几乎复制代码示例.看起来大多数东西都在工作除非如果我处于调试模式(传入 -c当然).出于某种原因，控制台窗口永远不会打开.
- 我遇到的另一个挑战是调用 StartUp()/ShutDown()控制台部分将无法编译.我最终必须初始化我的服务对象，然后调用它.
- 调用 Console.ReadKey() 方法时出现以下错误:
<块引用>
在以下任一情况下都无法读取密钥应用程序没有控制台或当控制台输入被重定向时从一个文件.试试 Console.Read.
我的代码和东西:
我的项目结构图:
注意:当我在 TestHarness 中复制启动序列时在调试模式下.如果/当我开始工作时，我会放弃它从解决方案.图书馆项目是我大部分工作的地方代码活着.

我找到了答案！我的项目属性设置为 Windows App 而不是 Console App.哦！(项目属性 > 应用程序选项卡 > 输出类型:)
I found some sample code posted at https://groups.google.com/group/microsoft.public.dotnet.languages.csharp/browse_thread/thread/4d45e9ea5471cba4/4519371a77ed4a74?hl=en&pli=1 for self installing a Windows Service. I am in C# on fx 4.0. Trying to figure out where I went off the rails...
My questions:
- I created a Win Service project. In program.cs / main() I pretty much copied the code example. It appears most everything is working except launching a console window if I am in DEBUG mode (passing in - c of course). For some reason the console window never opens.
- The other challenge I had was the call to StartUp() / ShutDown() in the console portion would not compile. I ended up have to initialize my service object and then call it.
- I am getting the following error when the Console.ReadKey() method is called:
Cannot read keys when either application does not have a console or when console input has been redirected from a file. Try Console.Read.
My code and stuff:
An image of my project structure:
NOTE: I was duplicating the startup sequence in the TestHarness when in DEBUG mode. If/when I get this working I will be dropping that from the solution. The Library project is where the majority of my code lives.

解决方案
And I found my answer! My project properties were set to Windows App instead of Console App. DOH! (Project Properties > Application Tab > Output type:)
