Question

Take a string such as:

In C#: How do I add ‘Quotes’ around string in a comma delimited list of strings?

and convert it to:

in-c-how-do-i-add-quotes-around-string-in-a-comma-delimited-list-of-strings

Requirements:

• Separate each word by a dash and remove all punctuation (taking into account not all words are separated by spaces.)
• Function takes in a max length, and gets all tokens below that max length. Example: ToSeoFriendly('hello world hello world', 14) returns 'hello-world'
• All words are converted to lower case.

On a separate note, should there be a minimum length?

Answer 1

Here is my solution in C#

private string ToSeoFriendly(string title, int maxLength) {     var match = Regex.Match(title.ToLower(), '[\\w]+');     StringBuilder result = new StringBuilder('');     bool maxLengthHit = false;     while (match.Success && !maxLengthHit) {         if (result.Length + match.Value.Length <= maxLength) {             result.Append(match.Value + '-');         } else {             maxLengthHit = true;             // Handle a situation where there is only one word and it is greater than the max length.             if (result.Length == 0) result.Append(match.Value.Substring(0, maxLength));         }         match = match.NextMatch();     }     // Remove trailing '-'     if (result[result.Length - 1] == '-') result.Remove(result.Length - 1, 1);     return result.ToString(); }
