Question

I have string:

string str = "GoodDay";

I need to retrieve the first three characters with the help of LINQ.

Any idea how to implement this?

Answer 1

String is IEnumerable<char> so you can query it. Use Enumerable.Take method:

IEnumerable<char> firstThreeChars = str.Take(3);

If it’s not required for you to use LINQ, then better option is usage of str.Substring(0,3) – that will return substring containing first three characters.
