Question

I have two arrayList

ArrayList ar1 = new ArrayList();
ArrayList ar2 = new ArrayList();

ar1 is having values { A,B,C,D}
and ar2 is having values {1,2,3,4}

I want to add these two array list such that
output should be

A 1
B 2
C 3
D 4

I have used
ar1.addrange(ar2);
and the output is like this
A
B
C
D
1
2
3
4

Any suggestions how to resolve this?

Answer 1

This should do the trick.

int max = Math.Max(ar1.Count, ar2.Count);
ArrayList ar3 = new ArrayList();

for (int i=0; i < max; i++)
{
    if (i < ar1.Count)
    {
       ar3.Add(ar1[i]);
    }
    if (i < ar2.Count)
    {
       ar3.Add(ar2[i]);
    }
}
