获取Window Service中虚拟目录的物理路径

Question

In my IIS server I have a Virtual Directory ("docPath") which is mapped with a physical folder of my machine.

I have a Window Service and from this service I need to get the Physical path of Virtual directory (created on IIS) ie "docPath" .

Since this is Windows service so I do not have HTTPContext object and I cannot use the HttpContext.Current.Server.MapPath("/docPath");

This is what I've tried so far:

I have tried to use the ServerManager from Microsoft.Web.Administration .

ServerManager serverManager = new ServerManager();
Site site = serverManager.Sites.FirstOrDefault(s => s.Name == "Default Web Site");
Application myApp = site.Applications["/docPath"];

But in Sites only web application created on IIS server are coming and not Virtual directories.

Also, System.Web.Hosting.HostingEnvironment.MapPath is also not working.

Could anybody let me know how can I get physical path of a Virtual Directory in Windows Service?

Add a generic handler to your web app, then have it return to you the physical path. In the generic handler you can have this code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace WebApplication2
{
    /// <summary>
    /// Summary description for PhysicalPathHandler
    /// </summary>
    public class PhysicalPathHandler : IHttpHandler
    {

        public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/plain";

            context.Response.Write(HttpContext.Current.Server.MapPath("docPath"));
        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }
}

Then you can use it like this in the windows service.

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("your-web-app-web-address-to-the-generic-handler"); //e.g. http://localhost:2950/PhysicalPathHandler.ashx

            string physicalPath = string.Empty; //this will store the physical path
            using (var response = (HttpWebResponse)request.GetResponse())
            {
                var encoding = Encoding.GetEncoding(response.CharacterSet);

                using (var responseStream = response.GetResponseStream())
                using (var reader = new StreamReader(responseStream, encoding))
                    physicalPath= reader.ReadToEnd();
            }

Remember to include the following namespaces into the windows service

using System.IO;
using System.Net;
using System.Text;
