用ASP.NET实现一个简单的计算器(适合入门者)

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;

}

</script>
<font id=Cau color=<%Response.Write(color);%>>用ASP+写得简易计算器</font>
<form runat="server">

<input id="A" runat="server"/>
<input id="B" 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"/>
