自已搞定了,要在引用里加入x801.dll,但为何开头不是已经<%@ Import Namespace="X801" %>了吗,不是很明白,请大侠请点一下
<%@ Import Namespace="X801" %>

<HTML>

	<script language="VB" runat="server">

  Dim Op1 As Single = 0

  Dim Op2 As Single = 0



  Public Sub Submit_Click(Sender As Object, E As EventArgs)

      Try

        Op1 = Single.Parse(Operand1.Text)

        Op2 = Single.Parse(Operand2.Text)

      Catch Exp As Exception

          ' Ignored

      End Try



      Dim Service As x801.x801 = New x801.x801()

    

      Result.Text = "<b>结果</b> = " & Service.Divide(Op1,Op2).ToString()
