相对路径的问题与.net Windows服务..？ [英] Relative Path issue with .Net Windows Service..?

问题描述

我有一个窗口服务，试图从应用程序目录访问XML文件。

I have a windows service which is trying to access an xml file from the Application directory.

Windows服务安装目录：C：\ SERVICES \为MyService \ MyService.exe
xml文件的路径：C：\ SERVICES \为MyService \ MyService.xml

Windows Service Installed directory : C:\Services\MyService\MyService.exe
Path of the xml file : C:\Services\MyService\MyService.xml

我想用下面的code访问该文件。

I am trying to access the file using the following code.

using (FileStream stream = new FileStream("MyService.xml", FileMode.Open, FileAccess.Read))
  {
         //Read file           
  }

我碰到下面的错误。

I get the following error.

找不到文件：C：\ WINDOWS \ SYSTEM32 \ MyService.xml

"Can not find file : C:\WINDOWS\system32\MyService.xml"

我的服务是本地系统帐户下运行，我不希望使用绝对路径。

My service is running with local system account and I don't want to use absolute path.

由于我的服务正在运行，既作为控制台/服务，我只是叫

As my service is running both as console/service I just called

Directory.SetCurrentDirectory(AppDomain.CurrentDomain.BaseDirectory) 

在运行它的服务例如。

static void Main(string[] args)
        {
            if (args.Length == 0)
            {
                Directory.SetCurrentDirectory(AppDomain.CurrentDomain.BaseDirectory);
                RunAsService();
            }
            else
            {
                RunAsConsole();
            }
        }
