Question

我发现了一些示例代码 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的C＃中。试找出我离开轨道的地方......

我的问题：

我创建了一个Win Service项目。在program.cs / main（）我几乎复制了代码示例。似乎大多数都在运作除了启动控制台窗口，如果我处于DEBUG模式（传入 - 当然是）。由于某种原因，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（）控制台部分无法编译。我最终不得不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：

无论何时都无法读取密钥应用程序没有控制台或控制台输入被重定向时从文件。试试Console.Read。

我的代码和内容：

我的项目结构图片：

注意：我在TestHarness中重复启动序列在DEBUG模式下。如果/当我得到这个工作，我会放弃它从解决方案。图书馆项目是我的大部分代码生活。

Answer 1

我找到了答案！我的项目属性设置为 Windows应用程序，而不是控制台应用程序。 DOH！（项目属性＆gt;应用程序选项卡＆gt;输出类型：）

Answer 2

另外..而不是使用-console arg，您可以使用Environment.UserInteractive来识别其控制台，当作为服务运行时它将是false，但在直接运行EXE时为true。

Answer 3

您还可以查看此内容：http://www.thedavejay.com/2012/04/self-installing-c-windows-service-safe.html

它允许您作为控制台应用程序进行调试，并将相同的应用程序安装为Windows服务，而无需更改项目类型。

在控制台模式下运行Windows服务？
