用ASP.NET实现一个简单的计算器

需以下三个文件: Calculate.aspx bin/Calculate.cs bin/Calculate.bat

步骤: 1.Calculate.cs 代码拷贝框
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; } } } }
[Ctrl+A 全部选择 然后拷贝]

2.Calculate.batcsc /t:library /out:Calculate.dll Calculate.cs

3.执行Calculate.bat4.Calculate.aspx

代码拷贝框
<%@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"/> 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<STRONG><A href="http://www.ltesting.net/html/55/category-catid-155.html" target="_blank" >.net</A></STRONG>写的简易计算器</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"/>
