Question

Why I have got this result?

Code:

List<int> samba = new List<int>(new int[]
            {1,2,0,0,0,0,3,2,1,
             0,0,0,0,0,0,0,0,0,
             });
  foreach (int i in samba)
            {
                label1.Text += samba[i];
            }

Result:

1201111002111111111

Answer 1

Perhaps you didn’t mean to print out the item at the index of the current item, but rather, but rather the current item:

List<int> samba = new List<int>(new int[]
{1,2,0,0,0,0,3,2,1,
    0,0,0,0,0,0,0,0,0,
    });
foreach (int i in samba)
{
    label1.Text += i;
}

The first time through your loop you’re printing out the item at position 1, which is 2. The second time you’re printing out the item at position 2, which is 0. Then you print out the item at position 0 four times, and that’s 1, etc.
