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 math=new math();
Message.Text=math.Mul(Convert.ToInt32(A.Value),Convert.ToInt32(B.Value)).ToString();
math.Color=C.Value;
color=math.Color;

}

</script>
