Not quite the same as LINQ in syntax terms, F# includes query expressions which are in essence it’s own style of LINQ.
If we assume we have a simple example of some code in C# which uses LINQ to get strings from an array where their length is 3. In C# this might look like the following
string[] sample = {"One", "Two", "Three", "Four", "Five"}; IEnumerable<string> result = from s in sample where s.Length == 3 select s;
Note: I’ve purposefully put each part of the LINQ query on a new line for easier comparison with the equivalent F# query expression.
So here’s the same in F#
let sample = [| "One" ; "Two" ; "Three" ; "Four" ; "Five" |] let result = query { for s in sample do where (s.Length = 3) select s }
The main differences are the use of the query expression syntax query { … } and the use of the for s in sample do instead of from s in sample
