Convert string to datetime value in LINQ

Question

Suppose I have a table storing a list of datetime (yyyyMMdd) in String format. How could I extract them and convert them into DateTime format dd/MM/yyyy ?

Answer 1

As already said, it's better to store date as date-type column in your DB, but if you want just to convert strings from one format to another, you can do this:

db.tb1.Select(x => String.Format("{0}/{1}/{2}", x.Substring(6, 2), x.Substring(4, 2), x.Substring(0, 4))
