Solution 2

If the type of dat field is string (e.g. varchar) then you have to use String.Format. I strongly suggest you reading the documentation[^].

What's to explain?
It gets a string date from a control, or array, converts it to a DateTime value, then formats it for the display as day-month-year. The only bit that you might not have seen before is the use of a formatting expression in a string.Format string:

{0:dd-MM-yyyy}

the 0 numbers the parameter that will supply the info
The colon specifies a format string is following
The dd-MM-yyyy part specifies the actual format to use for the DateTime value.

There is a list of the possible values for the DateTime formatting string here: Formatting a DateTime for display - format string description[^]
