如何检查Excel单元格的格式在C＃中，看看是否单元格的值是一个日期

早安所有！

我一直在开发一段时间中，用户可以发布一组值的一组日期的项目。

I have been developing a project for some time in which users can publish a set of values for a set of dates.

如用户将在Excel中选择一个范围，其中将包括日期值，以及其中包含的值公布对应于这些日期同样大小的范围。

e.g. The user would select a Range in Excel which would contain date values, and an equally sized Range which contains values to publish corresponding to these dates.

我需要做的（ C＃）是检查单元格格式的两个区域，看看哪一个是真正的日期，我一直在使用ExcelDNA因为所有日期为双打回来后，我可以在技术上分析我的'价值'为日期，并导致所有各种各样的问题。

What I need to do (C#) is check the cell formatting of both Ranges to see which one is 'actually' a date, I've been using ExcelDNA and since all dates are returned as doubles, I can technically parse my 'values' to dates, and cause all kinds of problems.

如果我能得到的单元格格式，我可以看到小区是否实际上意味着是一个约会！

If I can get the cell formatting, I can see whether the cell is actually meant to be a date!

先谢谢了。
