我想在某些条件下将数据从一个 DataTable 插入到另一个 DataTable 中。我发现这个链接很有用:http ://social.msdn.microsoft.com/Forums/en-US/csharplanguage/thread/7a5d0f88-3e71-435a-ae3c-ff01d1ca22a2/但我无法提出.ToList()
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()
