问题
I have created a windows service. I do the setup of the service using the windows installer. I have one XML file like a config file. Whenever i debug windows service with attaching the debug project it works fine. But after the installation i can see the event saying couldn't find the example.xml file in C:\Windows\system32. It's a repeating problem. Can anyone tell me whats going on with this. Or any suggestions?
回答1:
This isn't an installer problem. Windows Services are always started with System32 as the current directory. Add this line to the Main() method in your Program.cs prior to firing up any services.
Environment.CurrentDirectory = new FileInfo(Assembly.GetExecutingAssembly().FullName).DirectoryName;

Most likely file is just not where you are looking for it.
Chances are that your code looks in "current working folder" which during debugging in VS is the same as application, but in case of starting as service/from command line is different.
Make sure your code loads file from location you expect the file to be (i.e. next to the application), but not from some relative path (like "myfile.xml").

Why are you saving stuff in the Windows folders? Unless there's a really good reason to do so, this is bad. Install your config in the same place that your app is running and get the file path with:
var folderPath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
var configPath = Path.Combine(folderPath, configFileName);

The issue is that your service is not running as Administrator. If the service is not running as Administrator, then it won't be able to read the files under system32 folder.
Change the service properties to run as Administrator. That should fix the issue.
