Question

Can this be done using C# Linq?

For example:

peter piper picked a pack of pickled peppers, the peppers were sweet and sower for peter, peter thought

Result:

peter 3
peppers 2
picked 1
...

I can do it with a nested for loop, but was thinking there is a more concise, resource light way using Linq.

Answer 1

You can use GroupBy:

string original = "peter piper picked a pack of pickled peppers, the peppers were sweet and sower for peter, peter thought";

var words = original.Split(new[] {' ',','}, StringSplitOptions.RemoveEmptyEntries);
var groups = words.GroupBy(w => w);

foreach(var item in groups)
    Console.WriteLine("Word {0}: {1}", item.Key, item.Count());
