您可以使用匿名类型：

var a = DF_Utilities.
    GetAvailableTasks(empnum, 1).
    AsEnumerable().
    Where(p => p.Field<int>("task_code") == int.Parse(drpTasks.SelectedValue)).
    Select(p => new 
    {
        candNum = p.Field<int>("cand_num"),
        dataEntry = p.Field<int>("data_entry")
    }).
    First();
