推荐答案

ASP.NET无法压缩zip.它是生成HTML的引擎.没有某种添加库，C#和VB.NET将无法做到这一点.但是，J#可以做到这一点，关于如何使用J#的文章很多，如果您不在ASP.NET中，则可以使用J#库在C#或VB.NET中做到这一点.

ASP.NET can''t compress zips. It''s an engine for generating HTML. C# and VB.NET can''t do it without some sort of add in library. But, J# can do it, there''s tons of articles on how to use J# and you could use a J# library to do it in C# or VB.NET, if you''re in ASP.NET nor not.

For each of the solutions there is a function that needed to invoke from your web application, like if you use .NET Zip Library you have to use this code below

ZipFile zip= new ZipFile("MyNewZip.zip"); 
zip.AddDirectory("My Pictures", true); // AddDirectory recurses subdirectories
zip.Save(); 

希望对您有所帮助.
