求助：如何向DataView中添加一行数据

我需要从两个表结构完全相同的表里面，各选出若干条数据，然后放在一个DataView里面。目前写法是这样（先放到DataTable里面，然后根据DataTableNew一个DataView），但是有错：
DataTable dt = new DataTable();
for (int i = 0; i < BiaoDuanBH.Length; i++)
{
DataView dv_Temp = Epoint.MisBizLogic2.DB.ExecuteDataView("select * from KaiBiaoInfo_Temp where BiaoDuanGuid=(select BiaoDuanGuid from JSGC_BiaoDuanInfo where BiaoDuanNo='" + BiaoDuanBH[i] + "' )");
if (dv_Temp.Count != 0)
{
dt.Rows.Add(dv_Temp.Table.Rows[0].ItemArray);
//dt.Copy(dv_Temp.Table.Rows[0].ItemArray);
}
else
{
DataView drv = Epoint.MisBizLogic2.DB.ExecuteDataView("select * from KaiBiaoInfo where BiaoDuanGuid=(select BiaoDuanGuid from JSGC_BiaoDuanInfo where BiaoDuanNo='" + BiaoDuanBH[i] + "' )");
if (drv.Count != 0)
{
dt.Rows.Add(drv.Table.Rows[0].ItemArray);
}
}
}

你得为dt先new一个row ，然后这个row=dv_Temp.Table.Rows[0].ItemArray，然后dt.Rows.Add(newrow)
