Answer by Dragos Durlut for How to get relative path from absolute path

In ASP.NET Core 2, if you want the relative path to bin\Debug\netcoreapp2.2 you can use the following combination:

using Microsoft.AspNetCore.Hosting;using Microsoft.Extensions.Configuration;public class RenderingService : IRenderingService{    private readonly IHostingEnvironment _hostingEnvironment;    public RenderingService(IHostingEnvironment hostingEnvironment)    {    _hostingEnvironment = hostingEnvironment;    }    public string RelativeAssemblyDirectory()    {        var contentRootPath = _hostingEnvironment.ContentRootPath;        string executingAssemblyDirectoryAbsolutePath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);        string executingAssemblyDirectoryRelativePath = System.IO.Path.GetRelativePath(contentRootPath, executingAssemblyDirectoryAbsolutePath);        return executingAssemblyDirectoryRelativePath;    }}
