我想逐行阅读就是这样

问题描述

public static List<int> AssignmenBlock_IDs()
   {
       List<int> Block_IDsList = new List<int>();

       SqlConnection connecetion = ConnectingDatabase.GetConnection();
       string command = "SELECT ID FROM Assignment";
       SqlCommand commn = new SqlCommand(command, connecetion);


       SqlDataReader reader = commn.ExecuteReader();

       while (reader.Read())
       {
           Block_IDsList.Add(reader.GetInt32(0));
       }

       connecetion.Close();
       return Block_IDsList;

   }

将每个索引包含在每行的id中

will each index in the consist of id of each row
