使用Redfearn的公式。如果你谷歌，第一个或第二个结果指向GDATM，其中包括公式（和其他人的堆）。您必须自己编写C＃代码，但它们还包括可用于验证结果的Excel电子表格。

Use Redfearn''s formulae. If you google, the first or second result points you to GDATM, which includes the formulae (and heaps of others). You will have to write C# code yourself, but they also include Excel spreadsheets you can use to verify your results.
