有沒有想過從一次數據表中讀取一個完整列值並將其存儲在數組列表中？

Question

我嘗試過以下代碼，但它沒有給出正確的值，

ArrayList = outTable.Select("[FILTER_FLAG]").ToList();
//outTable is my data table having values in the column name "FILTER_FLAG"

Answer 1

        DataTable dataTable = new DataTable();

        dataTable.Columns.Add(new DataColumn("ID", typeof(int)));
        dataTable.Columns.Add(new DataColumn("Name", typeof(string)));

        dataTable.Rows.Add(1, "Mike");
        dataTable.Rows.Add(2, "Cris");
        dataTable.Rows.Add(3, "Ann");

        var _selector = dataTable.Rows.Cast<DataRow>().Select(x => x.Field<int>("ID")).ToList();

        ArrayList list = new ArrayList(_selector);
