Probably a function like this could work for you:

public static String SearchFileRecursive(String baseFolderPath, String fileName)
    {
        // Returns, if found, the full path of the file; otherwise returns null.
        var response = Path.Combine(baseFolderPath, fileName);
        if (File.Exists(response))
        {
            return response;
        }

        // Recursion.
        var directories = Directory.GetDirectories(baseFolderPath);
        for (var i = 0; i < directories.Length; i++)
        {
            response = SearchFileRecursive(directories[i], fileName);
            if (response != null) return response;
        }

        // { file was not found }

        return null;
    }
