Collection of array extension methods compatible with UdonSharp 1.x which adds partial feature set from List

Method	Parameters	Returns	Description
Add	T	T[]	Adds an item to an array
AddRange	T[]	T[]	Adds the elements of the specified collection to the end of the array
AddUnique	T	T[]	Adds an item to an array and ensures duplicates are not added
Contains	T	bool	Determines whether an element is in the array
FirstOrDefault		T	Returns the first element, or default value if the array is empty
GetElementTypeUdon		Type	Gets the element type of the array type
GetRange	Int, Int	T[]	Creates a shallow copy of a range of elements in the source
IndexOf	T (Int, Int)	Int	Returns the zero-based index of the first occurrence of a value in the T[]
Insert	Int, T	T[]	Inserts item to array at index
InsertRange	Int, T[]	T[]	Inserts the elements of a collection into the [] at the specified index
LastIndexOf	T (Int, Int)	Int	Returns the zero-based index of the last occurrence of a value in the T[]
LastOrDefault		T	Returns the last element, or default value if the array is empty
Remove	T	T[]	Removes item from array
RemoveAt	Int	T[]	Removes item at index from array
RemoveRange	Int, Int	T[]	Removes a range of elements from the T[]
Resize	Int	T[]	Resizes array
Reverse		T[]	Reverses Array

⚠️ For performance reasons this extension method library doesn't implement null checks! Please ensure the arrays you're accessing with the methods from this library are initialized.

Usage Demonstration

using UdonSharp;
using UnityEngine;
using Varneon.VUdon.ArrayExtensions;

public class UdonArrayExtensionDemo : UdonSharpBehaviour
{
    [SerializeField]
    private string[] strings;

    [SerializeField]
    private string[] range;

    [SerializeField]
    private string text;

    [SerializeField]
    private int index;

    [SerializeField]
    private int count;

    public void UsageDemo()
    {
        // Add item to array
        strings = strings.Add(text);

        // Add range of elements to array
        strings = strings.AddRange(range);
        
        // Check if item is contained in array
        Debug.Log(strings.Contains(text));

        // Get range of elements in array
        Debug.Log(string.Join("\n", strings.GetRange(index, count)));

        // Get the first index of element in array
        Debug.Log(strings.IndexOf(text));

        // Get the first index of element in array, starting at index
        Debug.Log(strings.IndexOf(text, index));

        // Get the first index of element in array in a range starting at index at the size of count
        Debug.Log(strings.IndexOf(text, index, count));

        // Insert item to array
        strings = strings.Insert(index, text);

        // Insert array of items to array
        strings = strings.InsertRange(index, range);

        // Get the last index of element in array
        Debug.Log(strings.LastIndexOf(text));

        // Get the last index of element in array, starting at index
        Debug.Log(strings.LastIndexOf(text, index));

        // Get the last index of element in array in a range starting at index at the size of count
        Debug.Log(strings.LastIndexOf(text, index, count));

        // Remove item from array
        strings = strings.Remove(text);

        // Remove item at index from array
        strings = strings.RemoveAt(index);

        // Remove range of elements from array
        strings = strings.RemoveRange(index, count);

        // Reverse array
        strings = strings.Reverse();

        // Get the first element in array
        Debug.Log(strings.FirstOrDefault());

        // Get the last element in array
        Debug.Log(strings.LastOrDefault());

        // Get the element type of a type
        Debug.Log(strings.GetType().GetElementTypeUdon());

        // Add unique item to array (if item exists in array, it won't be added)
        strings = strings.AddUnique(text);

        // Resize array
        strings = strings.Resize(index);
    }
}
