vb.net进行文件压缩

如果机器安装有winRar软件，就可以通过shell来借用他的功能达到压缩文件的效果；

参考代码如下：

Dim DeliveryF As String = Server.MapPath("..\Temp\DeliveryFactors.xls") '原始文件 (压缩前)

Dim TruckInfo As String = Server.MapPath("..\Temp\TruckInformation.xls")

Dim QDetail As String = Server.MapPath("..\Temp\QuotationDetail.xls")

'用shell命令调用winrar.exe创建压缩文件()

Dim winRarexe As String = "C:\Program Files\WinRAR\Rar" 'winzip 执行文件的位置

Dim wtarget As String = "C:\temp\QuotationVAComparsion.zip" '目地文件 (压缩后)

Dim command As String = winRarexe " a " wtarget " " DeliveryF " " TruckInfo " " QDetail

'这个命令你可以查看winrar的命令集

Dim retval As Double 'Shell 指令传回值

retval = Shell(command, AppWinStyle.MinimizedFocus)
