Tip: How to get Relative Path in .NET

In .NET, there is no straight method available to find a relative path either in Path class or other classes. Here is the utility method that will help to get you the relative path

       /// <summary>

       /// Get relative path for a given file path

       /// </summary>

       /// <param name="baseDirectory">Base directory</param>

       /// <param name="filePath">A file path</param>

       /// <returns>A relative path location</returns>

       public static string GetRelativePath(string baseDirectory, string filePath)

       {

          if (String.IsNullOrEmpty(baseDirectory))

              throw new ArgumentNullException("BaseDirectory");

          if (String.IsNullOrEmpty(filePath))

              throw new ArgumentNullException("FilePath");

          if (!baseDirectory.EndsWith("\\"))

              baseDirectory += "\\";

          System.Uri uri1 = new Uri(filePath);

          System.Uri uri2 = new Uri(baseDirectory);

          Uri relativeUri = uri2.MakeRelativeUri(uri1);

          return relativeUri.ToString();

       }
