将所选数据从DataTable复制到另一个DataTable [英] Copy selected data from DataTable to another DataTable

问题描述

我想从数据表中选择一些数据，并将其复制到另一个数据表中。我在一个问题中找到答案 - 如何查询内存中的DataTable以填充另一个数据表

I want to select some of the data from a datatable and copy it into another data table. I found the answer in one question - How to query a DataTable in memory to fill another data table

DataTable table = GetDataTableResults();
DataTable results = table.Select("SomeIntColumn > 0").CopyToDataTable();

此代码不起作用，导致错误 -

This code does not work and causes the error -

'System.Array' does not contain a definition for 'CopyToDataTable' and 
no extension method 'CopyToDataTable' accepting a first argument of type 
'System.Array' could be found (are you missing a using directive or 
an assembly reference?)

我正在使用visual studio 2008和.net 3.5。
