You want to access multiple TextBox that exists on your Form dynamically within the loop.

For this you will use the Find method:

Example:

for (int i =0; i< 10; i++)
{

        Control[] controls = this.Controls.Find("textBox" + i.ToString(), true);
        if (controls.Length > 0)
        {
            TextBox txtBox = controls[0] as TextBox;
            if (txtBox != null)
            {
                tabelaAlterarProdutosCalibresValores.precoVenda = txtBox.Text; 
            }
        }
        else
        {
          //não achou o textbox
        }

 }
