Question

有人可以帮助我如何在 VB.Net 中解压缩 zip 文件吗？

我使用“进口 Shell32”

Answer 1

如果您查看这篇 CodeProject 文章，它应该会对您有所帮助。如果您遇到具体问题，您需要将代码和问题描述放在您的问题中。

来自上面的文章：

Sub UnZip()
    Dim sc As New Shell32.Shell()
    'Create directory in which you will unzip your files .
    IO.Directory.CreateDirectory("D:\extractedFiles") 
    'Declare the folder where the files will be extracted
    Dim output As Shell32.Folder = sc.NameSpace("D:\extractedFiles")
    'Declare your input zip file as folder  .
    Dim input As Shell32.Folder = sc.NameSpace("d:\myzip.zip")
    'Extract the files from the zip file using the CopyHere command .
    output.CopyHere(input.Items, 4)

End Sub

Folder.CopyHere 方法的链接

或者，如果您使用的是 .Net 4.5，您可以使用 ZipFile Class

链接示例：

Imports System.IO
Imports System.IO.Compression

Module Module1

    Sub Main()
        Dim startPath As String = "c:\example\start" 
        Dim zipPath As String = "c:\example\result.zip" 
        Dim extractPath As String = "c:\example\extract"

        ZipFile.CreateFromDirectory(startPath, zipPath)

        ZipFile.ExtractToDirectory(zipPath, extractPath)
    End Sub 

End Module

我建议你下载http://dotnetzip.codeplex.com/，然后像这样使用它（示例取自文档）。

Dim ZipToUnpack As String = "C1P3SML.zip"  
Dim TargetDir As String = "C1P3SML"  
Console.WriteLine("Extracting file {0} to {1}", ZipToUnpack, TargetDir)   
Using zip1 As ZipFile = ZipFile.Read(ZipToUnpack)   
    Dim e As ZipEntry   
    For Each e In zip1   
        e.Extract(TargetDir, ExtractExistingFileAction.OverwriteSilently)   
    Next  
End Using
