Question

DataSet ds = new td_saledData();//实体类
td_saledBL tdsaled = new td_saledBL();//业务逻辑层
ds = tdsaled.GetHDAllBL();
td_saledData sakedData = new td_saledData();//gethdallbll()返回的实体类
bool fal = false;
foreach(DataRow row in ds.Tables[td_saledData.mTableTcSaled].Rows)
{
string cBillId = row[td_saledData.m_ref_no].ToString();
string iCurrency = row[td_saledData.m_sku].ToString();
string dbQuantity = row[td_saledData.m_t_qty].ToString();
string t_amount = row[td_saledData.m_t_amount].ToString();
string payamount = row[td_saledData.m_payamount].ToString();
string dbRate = "0";
hdlog.SendRetailLog(cBillId,iCurrency, Convert.ToDouble(dbQuantity),Convert.ToDouble(t_amount),Convert.ToDouble(payamount),Convert.ToDouble(dbRate));
hdlog.SendPaymentLog(cBillId,1,"null",Convert.ToDouble(payamount));
fal = hdlog.SendFinishLog(td_saledData.m_ref_no);
}
在执行到ds.Tables[td_saledData.mTableTcSaled]的时候报未将对象引用设置的对象的实例
大哥大姐们帮忙看下

Answer 1

foreach(DataRow row in ds.Tables["td_saledData.mTableTcSaled"].Rows)foreach(DataRow row in ds.Tables[0].Rows)

Answer 2

使用
dt.Tables["TableName"]或 dt.Tables[i]

Answer 3

foreach(DataRow row in ds.Tables["td_saledData.mTableTcSaled"].Rows)foreach(DataRow row in ds.Tables[0].Rows)
