public class MyObj

{

    public string Name { get; set; }

    public int ID { get; set; }

}

再数据库查询后的datatable我们想把它转成List<object>

我们可以这样做

private List<MyObj> test(DataTable dt)

{

    var convertedList = (from rw in dt.AsEnumerable()

        select new MyObj()

        {

            ID = Convert.ToInt32(rw["ID"]),

            Name = Convert.ToString(rw["Name"])

        }).ToList();

    return convertedList;

}

如果不确定object的类型，那我们可以这样做

private List<object> GetListByDataTable(DataTable dt)

{

    var reult = (from rw in dt.AsEnumerable()

        select new

        {

            Name = Convert.ToString(rw["Name"]),

            ID = Convert.ToInt32(rw["ID"])

        }).ToList();

    return reult.ConvertAll<object>(o => (object)o);

}
