C# 通过索引DevExpress在数据库中插入一些行

我的代码有一些问题。 在程序代码之前，单击“打开”按钮后，在DB中仅添加1行（选定行）。现在，我重新编写了这段代码，并需要根据这些行的索引在数据库中添加一些选中的行。此行中出现错误-

MyCommonClass.prSrvObject.SaveRequest（dsRequests、out-iErrId、out-sErrMsg）

List myList=new List（）；
int i=0；
对于（i=0；i0）和&（RequestActionId==7））
{
对于（i=0；i

在相应的行上引发了什么异常？请通过提供异常详细信息（似乎代码使用WinForms）来添加更多信息。无法更新数据库，因为sql&rownum=0数据库中的此错误，VS没有错误。当我正在解包时，在MyCommonClass.prSrvObject.SaveRequest行之后（dsRequests，out iErrId，out sErrMsg）停止工作。

List<int> myList = new List<int>();
int i = 0;
for (i = 0; i < MyCommonClass.OraDataSet.Tables["Table1"].Rows.Count; i++)
{
    object asd = MyCommonClass.OraDataSet.Tables["Tale1"].Rows[i]["CHECK_STATUS"];
    if (!(asd is DBNull))
    {
        Convert.ToBoolean(asd);
        myList.Add(i);
    }
}

if ((myList.Count > 0) && (RequestActionId == 7))
{
    for (i = 0; i < myList.Count; i++)
    {
        DataSet ds1 = new DataSet();
        ds1.Tables.Add(MyCommonClass.OraDataSet.Tables["table1"].Clone());
