    {
        string sentance, word;
        word = " ";
        char[] a = new char[] { ' ' };
        sentance = textBox1.Text;  //<--string here


        foreach (string s1 in sentance.Split(a))
        {
            if (word.Length < s1.Length)
            {
                word = s1;
            }
        }

Solution: To get all the third largest words

   string[] splitStr = sentence.Split(' ');

   if (splitStr.Length > 2)
   {
        List<int> allLengths = splitStr.Select(x => x.Length).Distinct().ToList();

        int thirdLargestWordLength = allLengths.OrderByDescending(x => x)
                                               .Skip(2).Distinct().Take(1).FirstOrDefault();

        if (splitStr[0].Length != thirdLargestWordLength && 
         splitStr[1].Length != thirdLargestWordLength)
         {

            string[] theThirdLargestWords = splitStr.Where(x => x.Length == thirdLargestWordLength)
                                                                  .ToArray();


             if (theThirdLargestWords.Length == 1)
             {
                label9.Text = "The third longest word is " + theThirdLargestWords[0];
             }
             else
             {
                string words = "";

                for (int i = 0; i < theThirdLargestWords.Length; i++)
                {
                   if (i == 0)
                   {
                     words = theThirdLargestWords[i];
                }
               //else if ((i + 1) == theThirdLargestWords.Length)
               //{
               //   words += " and " + theThirdLargestWords[i];
               //}
                else
                {
                    words += ", " + theThirdLargestWords[i];
                }
             }

             label9.Text = "The third longest words are " + words;
        }
      }
   }

I commented out the “and” part as i’m not sure if you want that in your string. I also added the first if statement so you don’t get an error if you have less then 3 words.
