Hello,

try out this :

C#

static void Main(string[] args)
       {

           //string sentence = "twinkle, twinkle, little star";
           do
           {
               Console.WriteLine("Enter a sentence");
               string sentence = Console.ReadLine();

               string[] data = sentence.Split(',', ' ');
               int count = 0;
               int original_count = data.Length;
               for (int i = 0; i < data.Length; i++)
               {
                   if (data[i] == "")
                       count++;
                   Console.WriteLine(data[i]);
               }

               original_count = original_count - count;
               Console.WriteLine(original_count.ToString());
               Console.WriteLine("Press enter to continue.......");
               Console.ReadLine();
               Console.Clear();

           } while (true);

       }

- This is a console application, when you run it when prompted simply enter the sentence whose count you want to find out. Also you need to add as many possible combinations of delimiters as you can think a person can put in his sentence.
- I have added a few.
- Try out different combinations and please do tell me.

Thanks,
Rahul

Solution 2

You can try this:

C#

string sentence = "Twinkle, Twinkle, Little Star";
string[] words = sentence.Split(new char[] { ' ', ',', '.', '!', ':', '?', ';' }, StringSplitOptions.RemoveEmptyEntries); // this splits the string into the words
var groups = words.GroupBy(x => x); // this groups the words
foreach (var group in groups)
{
    Console.WriteLine("{0} - {1}", group.Key, group.Count());
}

How this works: after splitting the sentence into words, you group the words. Then you iterate over all groups and you print the key (the word) and the count of words in the group.
