Array values from textboxes

Question

I have a 16 element int array and 16 textboxes (textBox1, textBox2 ....) that look like 4x4 matrix. Is there any way to put textboxes values to every array element not using code like this:

array[1] = (int)textBox1.Text;
array[2] = (int)textBox2.Text;

Answer 1

One possibility would be to store the references to the TextBox instances in an array.

TextBox[] Boxes;

And then use a 'for' loop to populate the values.

for (int i = 0; i < 16; i++)
{
   array[i] = (int)Boxes[i].Text;
}

Answer 2

You could use a function to get the text box's text as an integer using it's "index" from the form's control collection:

int GetBoxText(int index)
{
  return Convert.ToInt32(this.Controls["textBox" + i.ToString()].Text);
}

Note that this has no error checking of any kind. You could add some if you wanted to. All this does is get the text of the control named textBox + whatever i is from the form's control collection and convert it to an integer.
