在ASP.NET中操作文件的例子

1、写文件
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 声明一个StreamWriter对象
strwriterobj= File.CreateText("c:aspnet.txt") 新建一个文本文件,赋值给StreamWriter对象
strwriterobj.WriteLine( "Welcome to wonderfull world of ASP.NET Programming" )
向文件中写内容
strwriterobj.Close 关闭对象
Response.write("Done with the creation of text file and writing content into it")
%>

2、读文件
readfile.aspx

<%@ Import Namespace="System.IO" %>
<%
Response.write("Reading the content from the text file ASPNET.TXT <br>")
Dim streamreaderobj As StreamReader 声明一个StreamReader对象
Dim filecont As String 声明一个变量保存读出的内容
streamreaderobj = File.OpenText( "c:aspnet.txt" ) 打开文件赋值到StreamReader对象
Do 按行循环读取文件内容
filecont = streamreaderobj.ReadLine()
Response.Write( filecont & "<br>" )
Loop Until filecont = ""
streamreaderobj.Close 关闭StreamReader对象
Response.write("<br> Done with reading the content from the file aspnet.txt")
%>

3、删除文件
Filedelete.aspx

<%@ Import Namespace="System.IO" %>
<%
File.Delete("c:aspnet.txt" ) 删除文件
Response.write("The File aspnet is deleted successfully !!!" )
%>
