Here's an example of how to use LanguageExt to filter the first item in a list using C#:
var list = List(1,2,3,4,5);
var firstItem = list.Filter(x => x < 3) // filter for values less than 3
.Head(); // get the first element of the resulting list
Console.WriteLine(firstItem); // output: 1
In this example, we start with a list of integers and use the List
constructor from LanguageExt to create the list
variable. We then use the Filter
method to filter for elements with a value less than 3, which gives us a new List<int>
with the values {1,2}
. Finally, we use the Head
method to extract the first element of that list, which is 1
.
