Web API in Microsoft: What is the method to obtain a Server.MapPath?

In Microsoft Web API, trying to use approaches like these won’t work since it’s not based on MVC:

var absolutePath = Request.MapPath(“~”);

or even this:
var path = Server.MapPath(“~”);

These methods belong to the System.Web namespace and not System.Web.Http. How can I determine the corresponding server path using Web API? Previously, in MVC, I managed to achieve this with:
var fullPath = Request.MapPath(“~/Resources/images/” + imageName);
which would result in the full disk path:
“C:\inetpub\wwwroot\myWebFolder\Resources\images\myImage.jpg”

In Microsoft Web API, obtaining the server path requires a different approach since Request.MapPath and Server.MapPath are not directly available. Here’s a solution:

  1. Use HostingEnvironment to get the root path of the application.
  2. Combine it with the relative path using Path.Combine.

Here’s a code snippet illustrating this method:

using System.Web.Hosting;
using System.IO;

public string GetServerPath(string relativePath)
{
    var rootPath = HostingEnvironment.MapPath("~");
    return Path.Combine(rootPath, relativePath.TrimStart('~', '/').Replace('/', Path.DirectorySeparatorChar));
}

// Example usage 
string fullPath = GetServerPath("~/Resources/images/" + imageName);

This method effectively mirrors the approach used in MVC, providing you the full disk path.
