Question

I have a long string, want to break that string in new line after a predefined word count.

My string is look like:

A string is a data type used in programming, such as an integer and floating point unit, but is used to represent text rather than numbers. It is comprised of a set of characters that can also contain spaces and numbers.

I want to split in to new line this string after a 50 character.

Answer 1

string text = "A string is a data type used in programming, such as an integer and floating point unit, but is used to represent text rather than numbers. It is comprised of a set of characters that can also contain spaces and numbers.";

int startFrom = 50;
var index = text.Skip(startFrom)
                .Select((c, i) => new { Symbol = c, Index = i + startFrom })
                .Where(c => c.Symbol == ' ')
                .Select(c => c.Index)
                .FirstOrDefault();


if (index > 0)
{
    text = text.Remove(index, 1)
        .Insert(index, Environment.NewLine);
}
