泛型与SqlDataReader

从数据库中直接导出取道泛型里面.

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"]);
    }
