不使用CopyToDataTable即可将LINQ转换为DataTable

Question

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

Answer 1

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.
