推荐答案

我不知道ZIPPACKAGE.我正在使用来自CodePlex的DotNetZip库 [

I don''t know about the ZIPPACKAGE. I''m using DotNetZip Library from CodePlex[^]. It is easy to use in C# or VB.NET and the examples are good.

For instance the follow code would unzip all files in a WinZip file (using the DotNetZip code)

Imports Ionic.Zip

Private Sub UnzipFile(filename As String, targetFolder As String, password As String)
    Using zip As ZipFile = ZipFile.Read(filename)
        If String.IsNullOrEmpty(password) Then
            zip.Password = password
        End If

        zip.ExtractAll(targetFolder)
    End Using
End Sub
