是否有比通过Windows服务控制管理器启动服务,然后将调试器附加到线程更简单的方法来逐步遍历代码?这有点麻烦,我想知道是否有更直接的方法。

我认为这取决于你使用的操作系统,Vista很难附加到服务,因为会话之间的分离。

我过去使用的两个选项是:

Use GFlags (in the Debugging Tools for Windows) to setup a permanent debugger for a process. This exists in the "Image File Execution Options" registry key and is incredibly useful. I think you'll need to tweak the Service settings to enable "Interact with Desktop". I use this for all types of debugging, not just services. The other option, is to separate the code a bit, so that the service part is interchangable with a normal app startup. That way, you can use a simple command line flag, and launch as a process (rather than a Service), which makes it much easier to debug.

希望这能有所帮助。

第一行的Debugger.Break()怎么样?

下面是我用来测试服务的简单方法,没有任何额外的“调试”方法,并带有集成的VS单元测试。

[TestMethod]
public void TestMyService()
{
    MyService fs = new MyService();

    var OnStart = fs.GetType().BaseType.GetMethod("OnStart", BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance | BindingFlags.Static);

    OnStart.Invoke(fs, new object[] { null });
}

// As an extension method
public static void Start(this ServiceBase service, List<string> parameters)
{
     string[] par = parameters == null ? null : parameters.ToArray();

     var OnStart = service.GetType().GetMethod("OnStart", BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance | BindingFlags.Static);

     OnStart.Invoke(service, new object[] { par });
}

为了调试Windows服务,我结合了GFlags和一个由regedit创建的.reg文件。

运行GFlags,指定ex -name和vsjitdebugger 运行regedit并转到GFlags设置选项的位置 从文件菜单中选择“导出密钥” 将该文件保存在扩展名为.reg的某处 任何时候你想调试服务:双击.reg文件 如果要停止调试,请双击第二个.reg文件

或者保存以下代码片段并用所需的可执行名称替换servicename.exe。


debugon.reg:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\servicename.exe]
"GlobalFlag"="0x00000000"
"Debugger"="vsjitdebugger.exe"

debugoff.reg:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\servicename.exe]
"GlobalFlag"="0x00000000"

使用Windows Service Template c#项目创建一个新的服务应用程序https://github.com/HarpyWar/windows-service-template

有控制台/服务模式自动检测,自动安装/卸载您的服务,包括几个最常用的功能。
