How can i use linq to make a console application in C# for counting vowel in a sentence

I am trying make a program to count the number of vowels in a sentence but looks like it could be easily implemented with Linq. But have no idea about this. Please help me or provide some link.

Thanks,

That's definitely easy. You're just taking each letter in turn, and seeing if it's in one of another set. Fortunately, string implements IEnumerable<char>, so taking each character in turn is really natural with LINQ.

The Enumerable.Count method has an overload accepting a predicate - it returns the number of items in the sequence which match the predicate. Then you've just got to work out a predicate meaning "is this character a vowel". Using string.Contains(char) is the easiest way here.

This will do it:

int count = sentence.Count(c => "AEIOUaeiou".Contains(c));
