鴨爸的隨手寫寫

最近剛好有需要用到壓縮方式

當然第一件就是google一下人家怎麼做的啦

最後還是想到用7-zip(因為是freeware)

寫了一個簡單的壓縮方式

首先當然是要去抓7-zip的軟體啦

下載位址：http://www.7-zip.org/download.html

接著把7za.exe放到自已的專案裡面

然後就是程式碼了....

 

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        '參數一：要壓縮的檔名
        '參數二：要壓縮的檔案
        SevenZip("c:\test.zip", "c:\test\*.*", "")
End Sub

Public Sub SevenZip(ByVal ZipFileName, ByVal ZipSourcePath, ByVal ZipPassWord)
        Dim ZipPs As New Diagnostics.Process
        Try
            Dim strExec As String = Server.MapPath("7z/7za.exe")
            Dim strAgr As String
           '需要設定密碼
            If ZipPassWord <> "" Then
                strAgr = "a " & ZipFileName & " " & ZipSourcePath & " -p" & ZipPassWord
            Else
                '不需要密碼
                strAgr = "a " & ZipFileName & " " & ZipSourcePath & ""
            End If

            ZipPs.StartInfo.FileName = strExec
            ZipPs.StartInfo.Arguments = strAgr
            ZipPs.StartInfo.WindowStyle = Diagnostics.ProcessWindowStyle.Normal
            ZipPs.Start()
            ZipPs.WaitForExit()
            ZipPs.Close()
            If Dir(ZipFileName) <> "" Then
                Response.Write("Zip Complete.") 'check zip file complete
            End If
        Catch ex As Exception
            Response.Write(ex.Message)
        End Try
End Sub
