如何访问Windows服务中托管的WCF服务的App_Data文件夹中的文件 [英] How To access a file in the App_Data folder of WCF Service Hosted in Windows Service

问题描述

你好，

我有一个WCF服务，其app_data文件夹中有一个xml文件.
我在服务中有一个方法，可以使用System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath访问app_data文件夹中的xml文件.
当我在IIS中托管服务时，它运行良好.
但是当我使用Windows Service托管它时，它不起作用.
然后，我发现了"System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath".当服务托管在Windows Service中时，返回NULL.
请给我一个示例代码，以访问WCF服务的app_data文件夹中的xml文件，以便在我们将其托管在Windows Service中时可以正常工作.

I have a WCF Service That has an xml file in its app_data folder.
I have a method in the service that access the xml file in the app_data folder using System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath.
It worked fine when I hosted the service in IIS.
But It does not work when i host it using Windows Service.
I then discovered that "System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath" returns NULL when the service is hosted in Windows Service.
Please give me an idea with sample code to access the xml file in the app_data folder of the WCF service such that it should work fine when we host it in Windows Service.

推荐答案

使用HostingEnvironment.MapPath();方法，您应该能够找到所需的位置.   IntelliSense将为您提供所需的重载.

Using the HostingEnvironment.MapPath(); method, you should be able to get the location you are looking for.  IntelliSense will give you the overloads you will need.
