Regional Settings, especially dates, are always a problem in code. For example, suppose your product is developed in the U.S. and deployed in the UK. DateTime.Parse?would throw exceptions because String is not recognized as a valid DateTime). The quickest fix for this problem is to use the DateTimeFormatInfo object during the Parse:
System.Globalization.DateTimeFormatInfo MyDateTimeFormatInfo = new System.Globalization.DateTimeFormatInfo();MyDateTimeFormatInfo.ShortDatePattern = "M/d/yyyy";string StartDate = DateTime.Parse(dt.ToString("MM/dd/yyyy",MyDateTimeFormatInfo);
The above code will work with all short-date settings.
