A collection of helpful enumerable extension methods
Installation
Install-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 }
}
