A_TEST.master.cs代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;
public partial class A_TEST : System.Web.UI.MasterPage
{
protected void Page_Load(object sender, EventArgs e)
{
Panel pnl_item;
Label lab_fname;
HyperLink hlink_alltext, hlink_lines;
string[] sarr_fname = Directory.GetFiles(MapPath("files"), "*.txt");
foreach (string _s in sarr_fname) {
lab_fname = new Label();
lab_fname.Text = Path.GetFileName(_s);
hlink_alltext = new HyperLink();
hlink_alltext.Text = "全部读取";
hlink_alltext.NavigateUrl = "readalltext.aspx?fname="+lab_fname.Text;
hlink_lines = new HyperLink();
hlink_lines.Text = "分行读取";
hlink_lines.NavigateUrl = "readalllines.aspx?fname=" + lab_fname.Text;
pnl_item = new Panel();
pnl_item.Controls.Add(lab_fname);
pnl_item.Controls.Add(hlink_alltext);
pnl_item.Controls.Add(hlink_lines);
div_right.Controls.Add(pnl_item);
}
}
}
母版页首页.aspx代码如下：
<%@ Page Title="" Language="C#" MasterPageFile="~/A_TEST.master" AutoEventWireup="true" CodeFile="母版页练习.aspx.cs" Inherits="母版页练习" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="holder_main" Runat="Server">
</asp:Content>
新建两个页面 readalltext.aspx和readalllines.aspx。设置母版页为A_TEST.master
readalltext.aspx代码如下：
<%@ Page Title="" Language="C#" MasterPageFile="~/A_TEST.master" AutoEventWireup="true" CodeFile="readalltext.aspx.cs" Inherits="readalltext" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="holder_main" Runat="Server">
<asp:TextBox ID="txt_content" runat="server" Height="225px" Width="254px" TextMode="MultiLine" Rows="13"></asp:TextBox>
<asp:Button ID="btn_save" runat="server" Text="保存" οnclick="btn_save_Click" />
</asp:Content>
readalltext.aspx.cs代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;
public partial class readalltext : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack) {
if (Request.QueryString["fname"] != null)
{
string _path = Path.Combine(MapPath("files"), Request["fname"]);
if (File.Exists(_path))
{
txt_content.Text = File.ReadAllText(_path);
}
else { Response.Redirect("母版页练习.aspx"); }
}
else { Response.Redirect("母版页练习.aspx"); }
}
}
protected void btn_save_Click(object sender, EventArgs e)
{
string _path = Path.Combine(MapPath("files"), Request["fname"]);
File.WriteAllText(_path, txt_content.Text);
}
}
效果如图：
