下面是一個代碼示例,用於壓縮目錄中7天以前的文件,並創建一個具有相同名稱的壓縮文件,然後刪除現有的文件。在這個例子中,我們將使用.txt文件,但你可以改變它以適應。如何使用ZipSharpLib壓縮文件並使用現有文件名作爲新的Zip文件名(asp.net VB)

例如

myfile1.txt ---> myfile1.zip --->刪除myfile1.txt
myfile2.txt ---> myfile2.zip --->刪除myfile2.txt

Dim NumDays As Integer = 7 
Dim reportDbPath As String = Directory.GetParent(System.Reflection.Assembly.GetExecutingAssembly().Location).FullName() & "\report" 
Dim fileEntries As String() = Directory.GetFiles(reportDbPath) 
For Each fileName In fileEntries 
    If Path.GetExtension(fileName) = ".txt" AndAlso Directory.GetCreationTime(fileName) < DateAdd(DateInterval.Day, -NumDays, Now()) Then 
     Dim fi As New FileInfo(fileName) 
     Dim archiveFileName As String = Path.GetFileNameWithoutExtension(fileName) & ".zip" 
     Dim fsOut As FileStream = File.Create(Path.Combine(reportDbPath, archiveFileName)) 
     Dim zipStream As New ZipOutputStream(fsOut) 
     zipStream.SetLevel(9) 
     Dim newEntry As New ZipEntry(ZipEntry.CleanName(Path.GetFileName(fileName))) 
     newEntry.DateTime = fi.LastWriteTime 
     newEntry.Size = fi.Length 
     zipStream.PutNextEntry(newEntry) 
     Dim buffer As Byte() = New Byte(4095) {} 
     Using streamReader As FileStream = File.OpenRead(fileName) 
      StreamUtils.Copy(streamReader, zipStream, buffer) 
     End Using 
     zipStream.CloseEntry() 
     zipStream.IsStreamOwner = True 
     zipStream.Close() 
     File.Delete(fileName) 
    End If 
Next fileName 

希望它是有益的!

你有什麼問題。你在製作壓縮文件,命名壓縮文件,刪除文本文件等方面遇到麻煩嗎? –

你可以發佈你的代碼來壓縮文件嗎? –

究竟是什麼問題? (除了缺少的刪除部分)。我測試了它,它工作正常。它創建單獨的文件。 –

已經有了正確的代碼,所以問題不需要回答 - 轉換成HOWTO
