Using LINQ to parse the numbers from a string

Question

Is it possible to write a query where we get all those characters that could be parsed into int from any given string?

For example we have a string like: \"$%^DDFG

Answer 1

This will give you your string

string result = new String("y0urstr1ngW1thNumb3rs".
    Where(x => Char.IsDigit(x)).ToArray());

And for the first 3 chars use .Take(3) before ToArray()
