关于写入文件问题
我有2个textbox,1个用来显示文件的内容,另一个用于修改,程序如下
<%@ Page Language= "C# " AutoEventWireup= "true " CodeFile= "HtmlTo.aspx.cs " Inherits= "HtmlTo " validateRequest= "false " %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN " "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
<html xmlns= "http://www.w3.org/1999/xhtml " >
<head runat= "server ">
<title> 无标题页 </title>
</head>
<body>
<form id= "form1 " runat= "server ">
<div>
<asp:DropDownList ID= "DropDownList1 " runat= "server " AutoPostBack= "True ">
<asp:ListItem Value= "1.html "> 计算机科学与技术 </asp:ListItem>
<asp:ListItem Value= "2.html "> 生物工程 </asp:ListItem>
<asp:ListItem Value= "3.html "> 国际经济与贸易 </asp:ListItem>
<asp:ListItem Value= "4.html "> 园林 </asp:ListItem>
</asp:DropDownList> <br />
<br />
<asp:TextBox ID= "TextBox1 " runat= "server " Height= "480px " TextMode= "MultiLine " Width= "386px "> </asp:TextBox> <br />
<asp:TextBox ID= "TextBox2 " runat= "server "> </asp:TextBox> <br />
<br />
<asp:Button ID= "Button1 " runat= "server " Text= "确定 " OnClick= "Button1_Click " /> </div>
</form>
</body>
