利用SYSTEM.IO?名空間中的STREAMWRITER,STREAMREADER及FILE類,完成文件讀、寫、刪除的操作。?
--------------------------------------------------------------------------------
1、寫文件
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?????????'聲明一個StreamWriter對象
strwriterobj=?File.CreateText("c:/aspnet.txt")??'新建一個文本文件，賦值給StreamWriter對象
strwriterobj.WriteLine(?"Welcome?to?wonderfull?world?of?ASP.NET?Programming"?)?
????'向文件中寫內容
strwriterobj.Close?????????????'關閉對象
Response.write("Done?with?the?creation?of?text?file?and?writing?content?into?it")
%>

2、讀文件
readfile.aspx

<%@?Import?Namespace="System.IO"?%>
<%?
Response.write("Reading?the?content?from?the?text?file?ASPNET.TXT?
")
Dim?streamreaderobj?As?StreamReader?????????'聲明一個StreamReader對象
Dim?filecont?As?String?????????????????'聲明一個變量保存讀出的內容
streamreaderobj?=?File.OpenText(?"c:/aspnet.txt"?)?'打開文件賦值到StreamReader對象
Do????????????????????????'按行循環讀取文件內容
????filecont?=?streamreaderobj.ReadLine()?
????Response.Write(?filecont?&?"
"?)?
Loop?Until?filecont?=?""?
streamreaderobj.Close????????????????'關閉StreamReader對象
Response.write("
?Done?with?reading?the?content?from?the?file?aspnet.txt")
%>

3、刪除文件
Filedelete.aspx

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