泛型与SqlDataReader

从数据库中直接导出取道泛型里面.
命名空间：using System.Collections.Generic;

public static List<News> GetTopNews(int NewsKindId,int IntTop)

    {

        List<News> AllNews = new List<News>();

        string procname = "dbo.GetTopNews";

        SqlParameter[] prams ={ new SqlParameter("@NewsKindId", SqlDbType.Int),

                                new SqlParameter("@IntTop", SqlDbType.Int)};

        prams[0].Value = NewsKindId;

        prams[1].Value = IntTop;

        SqlDataReader Dr = DataBase.RunProcGetReader(procname,prams);

        while (Dr.Read())

        {

            AllNews.Add(new News(Dr));



        }

        Dr.Close();

        return AllNews;

    }

 
在News类中:

    public News(SqlDataReader Dr)

    {

        this._newsid = Convert.ToInt32(Dr["NewsId"]);

        this._newstitle = Convert.ToString(Dr["NewsTitle"]);

        this._newsbody = Convert.ToString(Dr["NewsBody"]);

        this._newskindid = Convert.ToInt32(Dr["NewsKindId"]);

        this._userid = Convert.ToInt32(Dr["UserId"]);

        this._pubdate = Convert.ToDateTime(Dr["PubDate"]);

    }
