how to add elements of two dynamic arraylist

Solution 1

int length1 = arr1.Count;
int length2 = arr2.Count;
int minLength= (length1<length2)?length1:length2;
int maxLength= (length1>length2)?length1:length2;
Console.WriteLine("The Resulted Array List Are:");
for(int i=0; i < minLength; i++)
{
Console.WriteLine(Convert.ToInt32(arr1[i])+Convert.ToInt32(arr2[i]));
}

if (minLength != maxLength)
{
if (arr1.Count == maxLength)
{
int i = minLength;
while (i != maxLength)
{
Console.WriteLine(Convert.ToInt32(arr1[i]));
i++;
}
}

if (arr2.Count == maxLength)
{
int i = minLength;
while (i != maxLength)
{
Console.WriteLine(Convert.ToInt32(arr2[i]));
i++;
}
}
}
Console.ReadLine();

Note: ArrayList is Object so dont forget to convert into respective type

// declare first array list and two items
ArrayList list = new ArrayList();
// you can add your list dynamically here it is manualy added for demo purpuse
list.Add(1);
list.Add(2);
// // declare 2nd array list and 4 items
ArrayList list2 = new ArrayList();
list2.Add(1);
list2.Add(2);
list2.Add(3);
list2.Add(4);
//if codition
if (list.Count > list2.Count)
{
for (int i = 0; i < list2.Count; i++)
{
Response.Write((int)list[i]+(int)list2[i]);
}
}
else if (list2.Count > list.Count)
{
for (int i = 0; i < list.Count; i++)
{
Response.Write((int)list[i] + (int)list2[i]);
}
}
//Note: Edit List items to see the effect
