我有一些asp代码来列出文件夹的内容(仅限txt文件)。我想知道是否有办法只列出最后创建的10个文件。
我的应用程序每天会创建一个文件,使用AAMMDD.txt作为名称。
我希望能够只列出最后10个文件。
这里有没有人可以分享???
提前谢谢。
这里是我发现列出所有内容的代码(我已对脚本进行了一些更改):
<%
Const ImageFilePath = "logs"
Dim objFSO
Dim objFolder
Dim objFile
Dim strFileName
Dim strFileExtension
Dim blnShowFiles
If Request.QueryString("ShowFiles") = "" Then
blnShowFiles = True
Else
blnShowFiles = CBool(Request.QueryString("ShowFiles"))
End If
Set objFSO = Nothing
%>
<style>
ul.dropdownPC, ul.dropdownPC li, ul.dropdownPC ul
{
list-style: none;
margin: 8px;
float: left;
vertical-align: middle;
padding:0px;
border:solid;
border-width:0px;
border-color:#ccc;
background-color: #fff;
}
ul.dropdownPC li
{
padding:5px;
border-width:0px;
}
</style>
<ul class="dropdownPC dropdown-horizontal">
<%
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
Set objFolder = objFSO.GetFolder(Server.MapPath(ImageFilePath))
For Each objFile In objFolder.Files
strFileExtension = LCase(Mid(objFile.Name, InStrRev(objFile.Name, ".", -1, 1) + 1))
If strFileExtension = "txt" Then
%>
<li><a href="<%= ImageFilePath & "/" & objFile.Name %>" target=_blank><img width="80" height="80" border="0" src="images/texticon01.png"><br><center><%= objFile.Name %></center></a>
<%
If blnShowFiles Then
%>
<!-- <%= objFile.Name %> --></li>
<%
Else
%>
<!-- <a href="<%=ImageFilePath & "/" & objFile.Name %>">View `Logs</a> --></li>`
<%
End If
%>
<%
End If
Next ' objFile
Set objFolder = Nothing
Set objFSO = Nothing
%>

你好。将文件名和创建日期放入记录集,对其进行排序并获得前十条记录。
<%
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
Set objFolder = objFSO.GetFolder(Server.MapPath(ImageFilePath))
'Required ADO Constants
Const adVarChar = 200
Const adDate = 7
Dim objRs
Set objRS = Server.CreateObject("Adodb.Recordset") 'Recordset for the sort
objRs.Fields.Append "FileName", adVarChar, 255
objRs.Fields.Append "CreateDate", adDate
objRs.Open
For Each objFile In objFolder.Files
strFileExtension = LCase(Mid(objFile.Name, InStrRev(objFile.Name, ".", -1, 1) + 1))
If strFileExtension = "txt" Then 'All Text Files Into Recordset
objRS.AddNew Array("FileName", "CreateDate"), Array(objFile.Name, objFile.DateCreated)
objRs.Update
End If
Next ' objFile
objRs.Sort = "CreateDate Desc"
For i = 1 To 10
If objRS.Eof Then Exit For
%>
<li><a href="<%= ImageFilePath & "/" & objRS("FileName") %>" target=_blank><img width="80" height="80" border="0" src="images/texticon01.png"><br><center><%= objRS("FileName") %></center></a>
<% If blnShowFiles Then %>
<!-- <%= objRS("FileName") %> --></li>
<% Else %>
<!-- <a href="<%=ImageFilePath & "/" & objRS("FileName") %>">View `Logs</a> --></li>`
<% End If %>
<%
objRS.MoveNext
Next
Set objFolder = Nothing
Set objFSO = Nothing
objRS.Close
Set objRS = Nothing
