ASP页面显示一条查询的记录的值
Hi 大虾们,麻烦告诉我应该咋做。

在我的页面里面有三个label, 分别为lblName,lblDID,lblExt我的后台在页面加载的时候的VB代码如下:
Dim cn As SqlConnection = New SqlConnection()
  cn.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings("SoftPhoneServices").ConnectionString
  If cn.State <> ConnectionState.Open Then
  cn.Open()
  End If
  Dim cm As SqlCommand = New SqlCommand()
  cm.CommandText = "SELECT Name, Extension FROM PVGL_PhoneList WHERE SAPID=@UserID"
  cm.Connection = cn
  Dim rd As SqlDataReader
  cm.Parameters.Add("@UserID", SqlDbType.Char, 10).Value = 'i00001'
  rd = cm.ExecuteReader()

  If Not rd.HasRows Then
  rd.Close()
  rd = Nothing
  cm.Dispose()
  cm = Nothing
  cn.Close()
  cn = Nothing
  lblExt.Text = "Unknow Ext."
  lblDID.Text = "Unknow DID"
  lblName.Text = "Unknow User"
  Else

  rd.Close()
  rd = Nothing
  cm.Dispose()
  cm = Nothing
  cn.Close()
  cn = Nothing
  End If
每个查询肯定是只有唯一的一条记录,我不知道如何将我查询出来那一行的Name, Extension 值赋给两个lable。高手指点一下吧。急用!

------解决方案--------------------
If rd.Read() Then
lblExt.Text = rd("Name").ToString()
lblDID.Text = rd("Extension ").ToString()


rd.Close()
rd = Nothing
cm.Dispose()
cm = Nothing
cn.Close()
cn = Nothing

Else

rd.Close()
rd = Nothing
cm.Dispose()
cm = Nothing
cn.Close()
cn = Nothing
End If
------解决方案--------------------
lblExt.Text = "Unknow Ext."

改成:
 lblExt.Text = rd("Name").ToString()
