Answer 1

SqlDataReader rs = ddrs.ExecuteReader();
this.Repeater1.DataSource = rs;
this.Repeater1.DataBind();
ddrs.Dispose();
conn.Close();

Answer 2

绑定Repeater 不用 if (rs.Read())

Answer 3

不用 if (rs.Read())
用if (sdr.HasRows)

Answer 4

没数据返回null ，不用read()

Answer 5

你用了rs.Read()的第一条已经读取了,DataList再读就是下一样了,当然就不显然了啊你可以用rs.HasRows来取代你的rs.Read()

Answer 6
