List<object> objects = new List<object>();

objects.Add(5);

I want to do

objects[0] += 10;

But I need to cast it first.

int a = (int) objects[0];
a += 10;

But doing this only changes a, not the integer in the list.

What’s the best way to solve this?

    You could do

    objects[0] = ((int)objects[0]) + 10;
