上面是之前代码，能直接运行

编译失败, Compilation, (56,13): error CS1069: The type name 'ZipArchive' could not be found in the namespace 'System.IO.Compression'. This type has been forwarded to assembly 'System.IO.Compression, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' Consider adding a reference to that assembly.
(56,30): error CS0103: The name 'ZipFile' does not exist in the current context

更新后提示这个，老大是最近哪里修改过吗

用的  普通模式v2 (Roslyn)

//css_ref System.IO.Compression.dll   添加这个后还是不行
