首先添加 using System.IO 命名空間。
代碼部分：

public string readfile(string paths)
{
StreamReader sr=new StreamReader(Server.MapPath(paths),System.Text.Encoding.Default);
string input =sr.ReadToEnd();
return input;
} |
上面為核心代碼，完整讀取檔案檔案代碼

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.IO;
namespace test
{
public partial class Text : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Response.Write(GetInterIDList("asp.txt"));
}
//讀取txt檔案的內容
public string GetInterIDList(string strfile)
{
string strout;
strout = "";
if (!File.Exists(System.Web.HttpContext.Current.Server.MapPath(strfile)))
{
}
else
{
StreamReader sr = new StreamReader(System.Web.HttpContext.Current.Server.MapPath(strfile), System.Text.Encoding.Default);
String input = sr.ReadToEnd();
sr.Close();
strout = input;
}
return strout;
} }

一行一行讀取檔案本檔案
