remove duplicate words from string in C#

Question

here is my code:

class Program
    {
        static void Main(string[] args)
        {
            string sentence = string.Empty;
            sentence = Con         


        

Answer 1

You could use Linq's Distinct extension method:

var sent = sentence.Split(' ').Distinct();

You can also use this to ignore the case of strings when comparing them—e.g. "WORD" and "word" would be considered duplicates:

var sent = sentence.Split(' ').Distinct(StringComparer.CurrentCultureIgnoreCase);
