How to get website's physical path on IIS 10?

Question

In my MVC app I want to get website's physical path on IIS server. My website's properties:

What I have tried is the following:

System.Diagnostics.Debug.WriteLine("MapPath: " + System.Web.Hosting.HostingEnvironment.MapPath("~/server/publish/"));  

The above line is returning the path where my project was created:

MapPath: C:\ProjectVisualStudio\Reporting\CS\ServerSide\server\publish\

So, to get the physical path on IIS server, I was trying to obtain it with:

int iisNumber = 2;  
  
            using (ServerManager serverManager = new ServerManager())  
            {  
                var site = serverManager.Sites.Where(s => s.Id == iisNumber).SingleOrDefault();  
                var applicationRoot = site.Applications.Where(a => a.Path == "~/server/publish/").SingleOrDefault(); //here I get the exception  
            //    var applicationRoot = site.Applications.SingleOrDefault();  
                var virtualRoot = applicationRoot.VirtualDirectories.Where(v => v.Path == "~/server/publish/").SingleOrDefault();  
                Console.WriteLine(virtualRoot.PhysicalPath);  
                System.Diagnostics.Debug.WriteLine("***************************************path IIS: " + virtualRoot.PhysicalPath + "***************************************");                 
            }  

But I get an exception

System.NullReferenceException: 'Object reference not set to an instance of an object.' site was null.

As you can see in the image, my site has the id = 2. Although running this:

       System.Diagnostics.Debug.WriteLine($"Available sites: {string.Join(", ", serverManager.Sites.Select(s => s.Id))}");    

is returnning:

Available sites: 1
Available sites: 1

What could I do to accomplish this task?

Answer 1

if you run your application with IIS, instead of IIS Express, the initial code is correct.

System.Diagnostics.Debug.WriteLine("MapPath: " + System.Web.Hosting.HostingEnvironment.MapPath("~/server/publish/"));

will return the IIS virtual directory path, not the IIS express one (which is mapped to the source).

a => a.Path == "~/server/publish/"

Maybe there is something wrong with your path, you can try the following code:

ServerManager serverManager = new ServerManager();    

// get the site (e.g. default)  
Site site = serverManager.Sites.FirstOrDefault(s => s.Name == "Default Web Site");  

// get the application that you are interested in  
Application myApp = site.Applications["/Dev1"];  

// get the physical path of the virtual directory  
Console.WriteLine(myApp.VirtualDirectories[0].PhysicalPath);
