how to use DateTime.Parse() to create a DateTime object

Use DateTime.ParseExact:

DateTime dateTime = DateTime.ParseExact("[Your Date Here]",
                                        "yyyyMMddHHmmssfff",  
                                        CultureInfo.InvariantCulture);

Here's the MSDN Docs.

You would have to use

DateTime time = DateTime.ParseExact(String,String, IFormatProvider);

The first argument string is going to be your date. The second argument string is going to be your format The third argument is your culture info (which is the IFormatProvider

So you would have

DateTime TimeStamp = DateTime.ParseExact(Data[1],"yyyyMMddHHmmssfff",CultureInfo.InvariantCulture);

The culture info is "A CultureInfo object that represents the culture used to interpret s. The DateTimeFormatInfo object returned by its DateTimeFormat property defines the symbols and formatting in s." From MSDN.

var sDate = "20110815174346225";
var oDate = DateTime.ParseExact(sDate, "yyyyMMddHHmmssfff", CultureInfo.CurrentCulture);
