在ASP.NET中操作檔案的例子 1、寫檔案 writefile.aspx <%@ Import Namespace="System.IO" %>        '引入所需的NameSpace <% Response.write("Writing the content into Text File in ASP.NET <BR>") Dim strwriterobj As StreamWriter         '聲明一個StreamWriter對象 strwriterobj= File.CreateText("c:/aspnet.txt")  '建立一個文字檔，賦值給StreamWriter對象 strwriterobj.WriteLine( "Welcome to wonderfull world of ASP.NET Programming" )     '向檔案中寫內容 strwriterobj.Close             '關閉對象 Response.write("Done with the creation of text file and writing content into it") %> 2、讀檔案 readfile.aspx <%@ Import Namespace="System.IO" %> <% Response.write("Reading the content from the text file ASPNET.TXT <br>") Dim streamreaderobj As StreamReader         '聲明一個StreamReader對象 Dim filecont As String                 '聲明一個變數儲存讀出的內容 streamreaderobj = File.OpenText( "c:/aspnet.txt" ) '開啟檔案賦值到StreamReader對象 Do                        '按行迴圈讀取檔案內容     filecont = streamreaderobj.ReadLine()     Response.Write( filecont & "<br>" ) Loop Until filecont = "" streamreaderobj.Close                '關閉StreamReader對象 Response.write("<br> Done with reading the content from the file aspnet.txt") %> 3、刪除檔案 Filedelete.aspx <%@ Import Namespace="System.IO" %> <% File.Delete("c:/aspnet.txt" )         '刪除檔案 Response.write("The File aspnet is deleted successfully !!!" ) %>
