美工作出来的页面都是html格式的~闲来无事~写了个程序用来转换html格式页面为aspx格式，并为之生成cs文件...-优快云博客

本文介绍了一个将HTML控件转换为ASP.NET服务器控件的方法。通过上传HTML文件，该程序能够自动将其转换，并创建对应的ASPX及ASPX.cs文件。转换过程中，支持将特定属性的控件转换为服务器控件。

defalut.aspx:

default.aspx
<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>

            runat="server" AutoPostBack="True" OnCheckedChanged="changeall_CheckedChanged" />change all the html control into server control?
        <asp:Button ID="Button1" runat="server" Text="change" OnClick="Button1_Click" />
        </div>

        }
    }

   }

程序功能尚在完善中，已经完成可以将所有html控件转换为server控件，下一步是将指定的控件进行转换
传上来，自己别弄掉了，日后再用 /Files/daiye/rar/html2aspx.rar
