Getting relative path to `bin\Debug\netcoreapp2.2` in ASP.NET Core 2

If you need the relative path of the executing assemblies, you will probably need something like this: ‘~\bin\Debug\netcoreapp2.2’

 

I recently had to do this because I had to render a razor view in an ASP.NET Core 2 application.

Tutorial here: https://scottsauber.com/2018/07/07/walkthrough-creating-an-html-email-template-with-razor-and-razor-class-libraries-and-rendering-it-from-a-net-standard-class-library/

Issue was that I had  to overcome a bug(https://stackoverflow.com/a/56504181/249895) that needed the relative netcodeapp2.2 that the asemblied resided in.

Example:

var viewPath = ‘~/bin/Debug/netcoreapp2.2/Views/MainView.cshtml’;

_viewEngine.GetView(executingFilePath: viewPath , viewPath: viewPath , isMainPage: true);

Getting the `bin\Debug\netcoreapp2.2` can be achieved by using this code:

 

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;
	}
}
