您好我尝试使用CopyToDataTable但没有Visual Studio 2010和2015的每个方法,请帮助我如何在不使用CopyToDataTable的情况下将Linq查询转换为DataTable或将其逐步发送给我以添加此方法
You can use originalTable.Clone()
and a loop with DataTable.ImportRow
:
DataTable tableResult = originalTable.Clone(); // empty
foreach(DataRow row in yourLinqQuery)
tableResult.ImportRow(row);
This has also one advantage over CopyToDataTable
: it doesn't cause an InvalidOperationException
if the query doesn't return any rows. With this approach the table will be empty.
