我有一个奇怪的事情发生，我在 VS2012 中制作的 C# 应用程序在 IIS 下的我的电脑上运行得很好，但是当我把它放在服务器上时，会发生什么我正在记录错误，例如，

    2013-07-02 10:08:44,572 [5] ERROR Castle.MonoRail.Framework.Views.NVelocity.NVelocityViewEngine [(null)] <(null)> - Could not render view
    NVelocity.Exception.MethodInvocationException: Invocation of method 'theme_skin_url' in  stellar.Services.themeService threw exception System.NullReferenceException : Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object.

    at Castle.MonoRail.Framework.Views.NVelocity.NVelocityViewEngine.Process(String viewName, TextWriter output, IEngineContext context, IController controller, IControllerContext controllerContext)

现在你会看到它正在寻找

d:\._GIT_\HIV PROJECT\stellar\Services\site_controlls\themeService.cs

但在它运行的服务器上

C:\inetpub\wwwroot\domain.com\Services\site_controlls\themeService.cs

现在我确定它不是在服务器上硬编码的，我什至在获取应用程序路径的方法上对 webconfig 中的根路径进行了近乎硬编码的长度。

        public static String root_path() {

            NameValueCollection section = (NameValueCollection)ConfigurationManager.GetSection("site_config");
            string setting = section["root"];
            if (String.IsNullOrWhiteSpace(setting)) return setting;


            String path = VirtualPathUtility.ToAppRelative("~");
            if (!String.IsNullOrWhiteSpace(path)) return path;

            path = Path.GetDirectoryName(new Uri(Assembly.GetExecutingAssembly().GetName().CodeBase).LocalPath).Replace("bin", "");
            return path;
        }

web.config 所在的位置

  <site_config>
        <add key="installed" value="False" />
        <add key="root" value="C:\inetpub\wwwroot\domain.com" />
  </site_config>

因此，令人困惑的是，当我获得服务器的日志时，我最终得到的是开发电脑的错误日志中的路径，我在而不是服务器上工作。

问题是，除了硬编码我的我，什么条件允许应用程序未加载、未使用但开发路径的路径？它在项目dll中吗？

您在那里看到的文件夹取自项目调试符号。它们只是为了让您知道文件在构建计算机上的位置。通常无法从您的代码中访问此信息，因此您遇到的错误可能是theme_skin_url.
