Solution 1

Try replacing dgvBarcode.Rows[0] with row so it actually uses your iterator of the foreach loop.

C#

string barcode = "";
            foreach (DataGridViewRow row in dgvBarcode.Rows)
            {
                barcode = row .Cells["Equipment Barcode"].Value.ToString();
            }
