从SQL获取数据并放入列表

sql

我从SQL获取数据并将其放在列表中。这就是我现在正在尝试的

public class Fruit //custom list
{
     public string aID { get;set; }  // can be more then 1
     public string bID { get;set; }  // only 2 but different aID
     public string name { get;set; } // only 1 for selection of aID and bID
}

这就是我从sql获取数据的方式,

var Fruitee = new Fruit();

using (SqlConnection cn = new SqlConnection(CS()))
{
      cn.Open();
      SqlCommand sqlCommand= new SqlCommand("SELECT * FROM myTable", cn);
      SqlDataReader reader = sqlCommand.ExecuteReader();
      while (reader.Read())
      {
             Fruitee.add(reader["aID"], reader["bID"],reader["name"]) // ??? not sure what to put here  as add is not available
      }
      cn.Close();
}

table看起来像这样

aID,bID,name

我被困在如何将项目添加到列表中,这 也是最佳实践吗?

List fruits = new List();

while (reader.Read())
{
    Fruit f = new Fruit();
    f.aID = (string) reader["aID"];
    f.bID = (string) reader["bID"];
    f.name = (string) reader["name"];
    fruits.Add(f);
}
