廢話少說,直接進入主題.

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

步驟:
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.執行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;

}

</script>
<font id=Cau color=<%Response.Write(color);%>>用ASP+寫得簡易計算器</font>
<form runat="server">

<input id="A" runat="server"/>
<input id="B" runat="server"/>
<input id="C" runat="server"/>
<asp:button Text="Add" OnClick="DoAdd" runat="server"/>
<asp:button Text="Sub" OnClick="DoSub" runat="server"/>
<asp:button Text="Mul" OnClick="DoMul" runat="server"/>
</form>
Result:<asp:label id=Message  runat="server"/>

5.總結
實在太爛,希望高手多多指教.(無限真誠)
