Being new does not give you a license to ask for codes online. You should try to learn. There are books, online tutorials, etc to read. Why ask for code without trying to do it by yourself?

Solution 2

Look at C# DateTime.Parse and DateTime.TryParse methods:
DateTime.Parse Method [^]
DateTime.TryParse Method[^]
Parsing Date and Time Strings[^]
