Remove values of one array from another C#

For two int arrays a and b, how would one go about removing the values of b from a? Working in C# here.

Sadly, arrays in c# are to me quite useless as they lack functions compared to javascript so i would use lists which have many functions and are really useful. Then you could scan through the values of each list using and remove any that equal each other. Below i have wrote some example code to solve your problem

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class CompareLists : MonoBehaviour {
    List<int> ListA;
    List<int> ListB;
    int i;
    int i2;
	// Use this for initialization
	void Start () {
        // intialize lists
        ListA = new List<int>{10, 9, 5};
        ListB = new List<int> {5, 4, 3, 10};

        // remove int that match one in list B
        while (i < ListA.Count)
        {
            i2 = 0;
            while (i2 < ListB.Count)
            {
                if (ListA *== ListB[i2])*

{
ListA.RemoveAt(i);
}
i2 = i2 + 1;
}
i = i + 1;
}

  • }*
    }
    I hope this works, honestly i have not tested it but at least it will put you in the right direction. Google ‘c# list’ to see all the other functions available and google ‘list unity’ to see the unity tutorial which is very helpful and well explained.
