  文件:
  Calculate.aspx
  bin/Calculate.cs
  bin/Calculate.bat

  步骤:
  1.Calculate.cs

  namespace Calculate
  {
  using System;
  public class math {

  public String _color;
  public int Add(int a,int b)
  {
  return a+b;
  }

  public int Sub(int a,int b)
  {
  return a-b;
  }

  public int Mul(int a,int b)
  {
  return a*b;
  }
  public String Color
  {
  get {
  return _color;
  }
  set {
  _color=value;
  }
  }

  }
  }

  2.Calculate.bat

  csc /t:library /out:Calculate.dll Calculate.cs

  3.执行Calculate.bat

  4.Calculate.aspx
  

  <%@Import NameSpace="Calculate"%>

  <script language="c#" runat="server">
  public String color;
  void DoAdd(Object Src, EventArgs E)
  {
  math math=new math();
  Message.Text=math.Add(Convert.ToInt32(A.Value),Convert.ToInt32(B.Value)).ToString();
  math.Color=C.Value;
  color=math.Color;

  }

  void DoSub(Object Src, EventArgs E)
  {
  math math=new math();
  Message.Text=math.Sub(Convert.ToInt32(A.Value),Convert.ToInt32(B.Value)).ToString();
  math.Color=C.Value;
  color=math.Color;
  }

  void DoMul(Object Src, EventArgs E)
  {
  math math=new math();
  Message.Text=math.Mul(Convert.ToInt32(A.Value),Convert.ToInt32(B.Value)).ToString();
  math.Color=C.Value;
  color=math.Color;

  }
