There are a huge number of ways to do this: this tip shows a number of them for newline characters: Counting Lines in a String[^] - but the principle is very much the same for whole words.

Probably the way you want to look is with a regex:

C#

string text = File.ReadAllText(@"D:\Temp\MyText.txt").ToLower();
int hellos = Regex.Matches(text, @"\bhello\b").Count;

returns the number of times "hello" appears in the file as a complete word.

Solution 1

first find all the words in the sentence( use space to find the words) and keep them in array and again loop through the array to find the matching words. you may need multiple loops. you can make it.. come on :)

Or a List<string> instead of array.
