@Bryian, well, thanks, but not quite.

Long back I had written this function both in C# and T-SQL for Indian Rupee. Can modify to suit the requirement and post it.

You want it in C#? I will be happy to write one for you. Just post the maximum number. Singular and plural words for whole and decimal digits. And assume comma at places just as English number as in ###,###,###.##.

This article might help : http://www.c-sharpcorner.com/article/coding-challenge-lesson-learned/

There is a sample code converting numbers to sentence: http://rextester.com/FTS88296 . I think you can modify and put some twist to it to tailor your need
