Answer 1

In asp net core you can get the path from IHostingEnvironment

public YourController(IHostingEnvironment env)
{
   _env = env;
}

And the method,

public void SaveImage(string base64img, string outputImgFilename = "image.jpg")
{
   var folderPath = System.IO.Path.Combine(_env.ContentRootPath, "imgs");
   if (!System.IO.Directory.Exists(folderPath))
   {
      System.IO.Directory.CreateDirectory(folderPath);
   }
   System.IO.File.WriteAllBytes(Path.Combine(folderPath, outputImgFilename), Convert.FromBase64String(base64img));
}
