Truncate a string without truncating/cutting words (if possible)

Filed under: Uncategorized — andreakn @ 15:04

heres a small snippets we’ve used to try and cut a string at a certain position, but accepting up to N extra letters if that means that we will not truncate in the middle of a word

   public static string TruncateAtWord(this string input, int length, int extraLength = 5)
            var absoluteMaxLength = length + extraLength;
            if (input == null || input.Length < absoluteMaxLength)
                return input;
            var nextSpace = input.LastIndexOf(" ", absoluteMaxLength, StringComparison.Ordinal);
            return string.Format("{0}...", input.Substring(0, (nextSpace > 0) ? nextSpace : length).Trim());
