converting strings into dates in C #

We are working with the string date format commonly used Datetime.pares () but this form of conversion is quite limited, and some C # is not going to understand the date format you write as 20031231. So how does a string like "20100101" or other forms be converted into a date type?

one, the form of stitching strings

II,convert.todatetime (String)

The string format is required and must be YYYY-MM-DD HH:MM:SS

Iii. Convert.todatetime (String, IFormatProvider)

DateTime DT;

DateTimeFormatInfo Dtformat = new System.globalizationdatetimeformatinfo ();

Dtformat.shortdatepattern = "YYYY/MM/DD";

DT = Convert.todatetime ("2011/05/26", Dtformat);

Iv.datetime.parseexact ()

String datestring = "20110526";

DateTime dt = DateTime.ParseExact (datestring, "YyyyMMdd", System.Globalization.CultureInfo.CurrentCulture);

Or

DateTime dt = DateTime.ParseExact (datestring, "YyyyMMdd", System.Globalization.CultureInfo.InvariantCulture);

V. Datetime.tryparse (String,out DateTime)

1, more often, will use the Datetime.tryparse (string,out datetime) method, because this method has security mechanism, when the string content is not correct, you can return the minimum value of the date MinValue. It is possible to determine the success of the conversion by returning the bool value. DateTime.ParseExact () needs to be converted in a specific format, with strict requirements for formatting, and an error if the string is not of the date content and the amount resembles "asdfasd".

2, after conversion with Datetime.tryparse (String,out datetime), the resulting datetime can be datetime. ToString ("ddd, MMM. DD ") to convert to a special demand format, more flexible and convenient.
