Soenneker.Extensions.Enumerable

A collection of helpful enumerable extension methods

Installation

dotnet add package Soenneker.Extensions.Enumerable

Usage

IEnumerable should have IsNullOrEmpty() too

var populatedList = new List<string>{"foo", "bar", "foo"};

populatedList.IsNullOrEmpty() // false

populatedList.Populated() // true
populatedList.None() // false

One call checking for null and contains any elements

List<string>? nullList = null;

nullList.IsNullOrEmpty() // true
nullList.Populated() // false

Duplicate handling

var containsDuplicates = populatedList.ContainsDuplicates(); // true

var deduped = populatedList.RemoveDuplicates(); // {"foo", "bar"}

Recursive flattening

public class Node 
{
 public string Name {get; set;}
 public List<Node> Children {get; set;}
}

void Example()
{
 var node = new Node(){ Name = "Node1" };
 node.Children = new List()
 {
 new Node() 
 {
 Name = "Node2"
 }
 }

 List<Node>? children = node.Children.ToFlattenedFromRecursive(c => c.Children);

 // Results in flattened List:
 // { Node1, Node2 }
}
