Group and count items
linq
Solution
Sure, here's the LINQ syntax in C#:
from word in words
group word into occurrences
select new
{
Word = occurrences.Key,
Count = occurrences.Count()
}
Or in "pure" C# method calls:
words.GroupBy(w => w)
.Select(o => new
{
Word = o.Key,
Count = o.Count()
});
And to create a distinct list of words you just use the Distinct operator:
words.Distinct();
Problem
I have a .csv file (words.csv) containing 5000 words seperated by commas. Most of the strings are repeated values. Can I use LINQ to do the following: A. group common words together and show count of repeated words so if apple has been repeated 5 times and banana 3 times..it should display as apple - 5 banana - 3 and so on B. Create another text file with duplicates removed.
