asp中文件与文件夹常用处理函数(文件后缀、创建文件等)

　　复制代码 代码如下:
=====================================
获得文件后缀
=====================================
Function Get_Filetxt(ByVal t0)
Dim t1
IF Len(t0)<2 Or Instr(t0,.)=0 Then Get_Filetxt=False:Exit Function
t1=Split(t0,.)
Get_Filetxt=Lcase(t1(Ubound(t1)))
End Function

=====================================
读取任何文件的纯代码
=====================================
Function LoadFile(ByVal t0)
IF Len(t0)=0 Then Exit Function
IF Sdcms_Cache Then
IF Check_Cache(LoadFile_&t0) Then
Create_Cache LoadFile_&t0,LoadFile_Cache(t0)
End IF
LoadFile=Load_Cache(LoadFile_&t0)
Else
LoadFile=LoadFile_Cache(t0)
End IF
End Function

Function LoadFile_Cache(ByVal t0)
Dim t1,stm
On Error Resume Next
IF Len(t0)=0 Then Exit Function
t1=Empty
Set Stm=Server.CreateObject(Adodb.Stream)
With Stm
.Type=2以本模式读取
.mode=3
.charset=CharSet
.Open
.loadfromfile Server.MapPath(t0)
t1=.readtext
.Close
End With
Set Stm=Nothing
IF Err Then
LoadFile_Cache=“&t0&”&Err.Description:Err.Clear
Else
LoadFile_Cache=t1
End IF
End Function

=====================================
检查文件是否存在
=====================================
Function Check_File(ByVal t0)
Dim Fso
t0=Server.MapPath(t0)
Set Fso=CreateObject(Scripting.FileSystemObject)
Check_File=Fso.FileExists(t0)
Set Fso=Nothing
End Function

=====================================
检查文件夹是否存在
=====================================
Function Check_Folder(ByVal t0)
Dim Fso
t0=Server.MapPath(t0)
Set Fso=CreateObject(Scripting.FileSystemObject)
Check_Folder=Fso.FolderExists(t0)
Set Fso=Nothing
End Function

=====================================
创建文件夹（无限级）
=====================================
Function Create_UpFile(ByVal t0)
Dim t1,t2,objFSO,i
On Error Resume Next
t0=Server.MapPath(t0)
IF InStr(t0,\)<=0 Or InStr(t0,:)<=0 Then:Create_upfile=False:Exit Function
Set objFSO=CreateObject(Scripting.FileSystemObject)
IF objFSO.FolderExists(t0) Then:Create_upfile=True:Exit Function
t1=Split(t0,\):t2=
For i=0 To UBound(t1)
t2=t2&t1(i)&\
IF Not objFSO.FolderExists(t2) Then objFSO.CreateFolder(t2)
Next
Set objFSO=Nothing
IF Err=0 Then Create_upfile=True:Else Create_upfile=False:Echo Create_upfile：&Err.Description&<br>:Err.Clear
End Function

Sub SaveFile(ByVal t0,ByVal t1,ByVal t2)
Dim objFSO,t3
Set objFSO=CreateObject(Scripting.FileSystemObject)
IF t0= Then Echo 目录不能为空！:Died
t3=Server.MapPath(t0)
IF t2= Or IsNull(t2) Then t2=
IF objFSO.FolderExists(t3)=False Then Create_upfile(t0)
BuildFile t3&\&Trim(t1),t2
Set objFSO=Nothing
End Sub

Function BuildFile(ByVal t0,ByVal t1)
Dim Stm
On Error Resume Next
Set Stm=Server.CreateObject(Adodb.Stream)
With Stm
.Type=2 以本模式读取
.Mode=3
.Charset=CharSet
.Open
.WriteText t1
.SaveToFile t0,2
.Close
End With
Set Stm=Nothing
IF Err Then Echo BuildFile：&Err.Description&<br>:Err.Clear
End Function

=====================================
重命名文件夹
=====================================
Sub RenameFile(ByVal t0,ByVal t1)
Dim Fso
On Error Resume Next
Set Fso=Server.CreateObject(Scripting.FileSystemObject)
IF Fso.FolderExists(Server.MapPath(t0)) Then
Fso.MoveFolder Server.MapPath(t0),Server.MapPath(t1)
End IF
Set Fso=Nothing
IF Err Then Echo Renamefile：&Err.Description&<br>:Err.Clear
End Sub

=====================================
重命名文件
=====================================
Sub RenameHtml(ByVal t0,ByVal t1)
Dim Fso
On Error Resume Next
Set Fso=Server.CreateObject(Scripting.FileSystemObject)
IF Fso.FileExists(Server.MapPath(t0)) Then
Fso.MoveFile Server.MapPath(t0),Server.MapPath(t1)
End IF
Set Fso=Nothing
IF Err Then Echo Renamehtml：&Err.Description&<br>:Err.Clear
End Sub

=====================================
删除文件夹
=====================================
Sub DelFile(ByVal t0)
Dim Fso,F
On Error Resume Next
Set Fso=Server.CreateObject(Scripting.FileSystemObject)
Set F=fso.GetFolder(Server.MapPath(t0))
IF Not IsNull(t0) Then F.Delete True
IF Err Then Echo Delfile：&Err.Description&<br>:Err.Clear
End Sub

=====================================
删除文件
=====================================
Sub DelHtml(ByVal t0)
Dim Fso
On Error Resume Next
Set Fso=Server.CreateObject(Scripting.FileSystemObject)
IF Fso.FileExists(Server.MapPath(t0)) Then Fso.DeleteFile Server.MapPath(t0)
IF Err Then Echo DelHtml：&Err.Description&<br>:Err.Clear
End Sub

Function Re_FileName(ByVal t0)
Dim t1
t0=Lcase(t0)
IF Len(t0)=0 Then Re_FileName={id}:Exit Function
t1=Now()
处理自定义文件名

IF Instr(t0,{)>0 And Instr(t0,})>0 Then
IF Instr(t0,{id})=0 Then
t0=t0&{id}尽量防止重复
End IF
End IF
t0=Replace(t0,{y},Year(t1))
t0=Replace(t0,{m},Right(0&Month(t1),2))
t0=Replace(t0,{d},Right(0&Day(t1),2))
t0=Replace(t0,{h},Right(0&Hour(t1),2))
t0=Replace(t0,{mm},Right(0&Minute(t1),2))
t0=Replace(t0,{s},Right(0&Second(t1),2))
Re_FileName=t0
End Function
