DataTable List 相互转换

This uses the FastMember‘s meta-programming API for maximum performance. If you want to restrict it to particular members (or enforce the order), then you can do that too:

IEnumerable<SomeType> data = ...
DataTable table = new DataTable();
using(var reader = ObjectReader.Create(data, "Id", "Name", "Description")) {
    table.Load(reader);
}
使用类库: https://github.com/mgravell/fast-member

var list = dataTable.Rows.OfType<DataRow>()
    .Select(dr => dr.Field<string>(columnName)).ToList();
