用asp+实现一个简单的计算器(适合入门者)
废话少说,直接进入主题.
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"/>
<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.总结
实在太烂,希望高手多多指教.(无限真诚)
