我有一个将字段列表插入数据库的程序。当我使用自己的计算机插入日期时间字段时，它看起来完成得很好。但是，当我使用 Windows 7 中文版插入它时，该字段变为 0000-00-00 00:00:00 这是命令

MySqlCommand myCommand4 = new MySqlCommand("Insert into OrderRecords_table values('" + OrderIDLabel.Text + "','" + customerCode + "','" + customer + "','" + TelComboBox.Text + "','" + LicenseComboBox.Text + "','" +
                      DriverComboBox.Text + "','" + AddressComboBox.Text + "','" + LocationTypeComboBox.Text + "','" + PickupComboBox.Text + "','" + CustomerTypeLabel.Text + "','" +
                      Convert.ToDecimal(TotalPriceLabel.Text) + "','" + status + "','" + note + "','" + sandReceiptNo + "','" + createtiming + "','" + Convert.ToDateTime(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")) + "')", myConnection);
myCommand4.ExecuteNonQuery();

我知道它看起来有点乱，但它所说 STR_TO_DATE('" + DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") + "','%Y/%M/%d /%H/%m/%s'))" 的部分是我插入当前日期时间的部分。当我使用英文版的 Windows 时它工作得很好，但是每当我使用中文版时，它不是 0000-00-00 00:00:00 而不是实际时间，我试图更改在控制面板中显示日期的格式，但它仍然有同样的问题。

有谁知道问题是什么？

谢谢

编辑了我的代码

var sql = "insert into OrderRecords_table values(@OrderID, @customercode, @customer, @PhoneNumber, @license, @driver, @address, @type, @pickupLocation, @PaymentMethod, @totalPrice, @status, @notes, @sandreceiptNo,@createTime, @EditTime)";

            using (var myCommand4 = new MySqlCommand(sql, myConnection))
            {        
                       myCommand4.Parameters.AddWithValue("@orderId", MySqlDbType.VarChar).Value = OrderIDLabel.Text;
                myCommand4.Parameters.AddWithValue("@customercode", MySqlDbType.VarChar).Value =  customerCode;
                myCommand4.Parameters.AddWithValue("@customer",MySqlDbType.VarChar).Value = customer;
                myCommand4.Parameters.AddWithValue("@PhoneNumber", MySqlDbType.VarChar).Value =TelComboBox.Text;
                myCommand4.Parameters.AddWithValue("@license", MySqlDbType.VarChar).Value = LicenseComboBox.Text;
                myCommand4.Parameters.AddWithValue("@driver", MySqlDbType.VarChar).Value = DriverComboBox.Text;
                myCommand4.Parameters.AddWithValue("@address", MySqlDbType.VarChar).Value = AddressComboBox.Text;
                myCommand4.Parameters.AddWithValue("@Type", MySqlDbType.VarChar).Value = LocationTypeComboBox.Text;
                myCommand4.Parameters.AddWithValue("@pickupLocation", MySqlDbType.VarChar).Value = PickupComboBox.Text;
                myCommand4.Parameters.AddWithValue("@PaymentMethod", MySqlDbType.VarChar).Value = CustomerTypeLabel.Text;
                myCommand4.Parameters.AddWithValue("@totalPrice", MySqlDbType.Decimal).Value = Convert.ToDecimal(TotalPriceLabel.Text);
                myCommand4.Parameters.AddWithValue("@status", MySqlDbType.VarChar).Value = status;
                myCommand4.Parameters.AddWithValue("@notes",  MySqlDbType.VarChar).Value =status;
                myCommand4.Parameters.AddWithValue("@sandreceiptNo", MySqlDbType.VarChar).Value = sandReceiptNo;
                myCommand4.Parameters.AddWithValue("@createTiming", MySqlDbType.DateTime).Value = createtiming;
                myCommand4.Parameters.AddWithValue("@EditTime", MySqlDbType.DateTime).Value = DateTime.Now;
                myCommand4.ExecuteNonQuery();

它说我有一些无效的输入，但我检查了几次所有字段都分配给了正确的类型...... 不知道发生了什么

我已将您的代码重写为更标准化的实现（使用最佳实践）。请注意，我已将您的查询提取到一个单独的变量中，以使代码和查询变得更具可读性。

var sql = "insert into orderrecords_table values " +
          "(@orderId,                            " +
          " @customercode,                       " +
          " @customer,                           " +
          " @telephone,                          " +
          " @license,                            " +
          " @driver,                             " +
          " @address                             " +
          " @locationType,                       " +
          " @pickup,                             " +
          " @customerType,                       " +
          " @totalPrice,                         " +
          " @status,                             " +
          " @note,                               " +
          " @sandreceiptNo,                      " +
          " @createTiming,                       " +
          " @currentTime)                        ";

using (var myCommand4 = new MySqlComm## Heading ##and(sql, connection))
{
   myCommand4.Parameters.AddWithValue("@orderId", OrderIDLabel.Text) ;
   myCommand4.Parameters.AddWithValue("@customercode", customerCode);
   myCommand4.Parameters.AddWithValue("@customer", customer);
   myCommand4.Parameters.AddWithValue("@telephone", TelComboBox.Text);
   myCommand4.Parameters.AddWithValue("@license", LicenseComboBox.Text);
   myCommand4.Parameters.AddWithValue("@driver", DriverComboBox.Text);
   myCommand4.Parameters.AddWithValue("@address", AddressComboBox.Text);
   myCommand4.Parameters.AddWithValue("@locationType", LocationTypeComboBox.Text);
   myCommand4.Parameters.AddWithValue("@pickup", PickupComboBox.Text);
   myCommand4.Parameters.AddWithValue("@customerType", CustomerTypeLabel.Text);
   myCommand4.Parameters.AddWithValue("@totalPrice", Convert.ToDecimal(TotalPriceLabel.Text));
   myCommand4.Parameters.AddWithValue("@status", status);
   myCommand4.Parameters.AddWithValue("@note", status);
   myCommand4.Parameters.AddWithValue("@sandreceiptNo", sandReceiptNo);
   myCommand4.Parameters.AddWithValue("@createTiming", createtiming);
   myCommand4.Parameters.AddWithValue("@currentTime", DateTime.Now);

   myCommand4.ExecuteNonQuery();
}
