Answer 1

What do you mean by removing the limit?
Arrays have fixed size that cannot change. If you need to adjust the size dynamically, you should use a List<int> instead.

Answer 2

I want the user to set the size of the array.

I see thank you.

Answer 3

you get user input and you save it at elemNum. Why not use that?

int[] arr = new int[elemNum];

Answer 4

How could I miss that.
HAHAHA thanks

Answer 5

or use List and eliminate the problem of knowing how many items are going to be entered beforehand.

using System;
using System.Collections.Generic;

namespace Program {
class Test {
public static void Main() {
List<int> li1 = new List<int>();
while(true)
{
string i = Console.ReadLine();
if(i == null)
break;
else{
try{
li1.Add(int.Parse(i));}
catch{
//ignore invalid entries
continue;}
}
}
li1.ForEach(i => Console.Write("{0}, ", i));;
}
}
}
