I tried to avoid dll imports so the best way for me was to use System.Linq and the System.IO.Directory class.

For your example Real path is: d:\src\File.txt The user give me: D:\src\file.txt

Code for this:

using System.Linq;

public static class PathUtils
{
    public static string RealPath(string inputPath)
    {
        return Directory.GetFiles(Path.GetDirectoryName(inputPath))
            .FirstOrDefault(p => String.Equals(Path.GetFileName(p), 
                Path.GetFileName(inputPath), StringComparison.OrdinalIgnoreCase));
    }
}

var p = PathUtils.RealPath(@"D:\src\file.txt");

Method should return the path "d:\src\File.txt" or "D:\src\File.txt".
