在“ System.IO.Compression”命名空间中找不到“ ZipArchive” [英] Cannot find `ZipArchive` in the “System.IO.Compression” namespace
问题描述
我的问题与
但是我为我的4.5.1 Webforms项目引用了DLL：
我项目的属性给我：目标框架：.Net Framework 4.5.1。
和web.config：
< compilation debug = true targetFramework = 4.5 />
我想念什么？
解决方案是在web.config中手动引用程序集，但是为什么呢？为什么添加引用对话框中的复选框不够？
< assemblies>
< add assembly = System.IO.Compression，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = B77A5C561934E089 />
< add assembly = System.IO.Compression.FileSystem，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = B77A5C561934E089 />
< / assembly>

解决方案
1 ）从nuget处安装system.Io.compression
2）从nuget安装系统.Install-Package 40-System.IO.Compression.FileSystem。
System.IO.Compression.FileSystem
My question is related to I didn't find "ZipFile" class in the "System.IO.Compression" namespace
But I have referenced the DLL's for my 4.5.1 webforms project:
Properties of my project give me: Target framework: .Net Framework 4.5.1.
and the web.config:
<compilation debug="true" targetFramework="4.5" />
What am I missing?
The solution was to manually reference the assemblies in the web.config But why? Why wasn't the checkbox in the add reference dialog insufficient?
<assemblies>
<add assembly="System.IO.Compression, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />
<add assembly="System.IO.Compression.FileSystem, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />
</assemblies>
Taken from this answer to "Installed .Net 4.5 but can't use ZipFile class in Visual C#"
I faced same problem because the namespace is not present in References,Please do the following steps.
In my case Without References
After Installing References
Solution
1)Install system.Io.compression from nuget here
2)Install system.Install-Package 40-System.IO.Compression.FileSystem from nuget here.
System.IO.Compression.FileSystem
