我正在尝试使用 for-if 循环来运行几个 CheckBoxList 控件，以查看是否选中了复选框。如果选中，它将向数据库运行 INSERT 语句。
我的第一个 CheckBoxList (stapleCheckBoxList) 可以正常工作（例如，如果我选择了所有 4 个复选框，则相应的项目将被插入到数据库中）。但是，对于我的第二个 CheckBoxList (seafoodCheckBoxList)，它似乎只在第一个选中的复选框上执行 INSERT。谁能找出我下面的代码有什么问题？
protected void btnTSubmit_Click(object sender, EventArgs e)
{
int i;
int intOrderNo = (int)Session["sOrderNo"];
int Qty;
int UnitPrice;
string ProdId;
if (txtPaxQty.Text != String.Empty)
{
UnitPrice = 12;
Qty = int.Parse(txtPaxQty.Text);
ProdId = "PK001";
OleDbConnection DBconn2 = new OleDbConnection();
DBconn2.ConnectionString = "Provider = Microsoft.Jet.OLEDB.4.0;Data source="

cmd.Connection = DBconn2;
cmd.CommandType = System.Data.CommandType.Text;
cmd.CommandText = "INSERT INTO itemsTable(iOrderNo, iProductId, iQty, iUnitPrice)"
+ "VALUES (@OrderNo, @ProductId, @Qty, @UnitPrice)";
cmd.Parameters.AddWithValue("@OrderNo", intOrderNo);
cmd.Parameters.AddWithValue("@ProductId", ProdId);
cmd.Parameters.AddWithValue("@Qty", Qty);
cmd.Parameters.AddWithValue("@UnitPrice", UnitPrice);
DBconn2.Open();
cmd.ExecuteNonQuery();
DBconn2.Close();
