c# - 从数据表插入数据表

Question

我想在某些条件下将数据从一个 DataTable 插入到另一个 DataTable。我发现此链接很有用:http://social.msdn.microsoft.com/Forums/en-US/csharplanguage/thread/7a5d0f88-3e71-435a-ae3c-ff01d1ca22a2/但我不能把.ToList()对于我的查询。我收到以下错误:

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

有人可以帮我解决这个问题吗？

PS:我的查询:

(from crow in dtConfiguration.AsEnumerable()
                         where crow.Field<string>("FieldType") == "FL"
                         & crow.Field<string>("FieldName") != "DATEADDED"
                         & crow.Field<string>("FieldName") != "DATEMODIFIED"
                         select crow).ToList()

将以下语句添加到您的代码中:
