在.Net CORE 1.0中解压缩存档 [英] Unzip archive in .Net CORE 1.0

问题描述

我目前正在研究ASP.NET Core 1.0项目。我想同时留在 dnxcore50 和 dnx451 上。现在把我带到以下问题：

I'm currently working on an ASP.NET Core 1.0 project. I want to stay on the dnxcore50 and the dnx451 at the same time. Which brings me to the following issue now:

如何将zip压缩文件从文件系统解压缩到目录中？

How can I unzip a zip archive from the filesystem to a directory?

"System.IO.FileSystem.Primitives": "4.0.0-beta-22816",
"System.IO.FileSystem": "4.0.0-beta-22816"

"frameworks": {
    "dnx451": {
      "frameworkAssemblies": {
        "System.IO": ""
      }
    },
    "dnxcore50": {
      "dependencies": {
        "System.IO": "4.0.10-beta-*"
      }
    }
  }

在project.json中使用该配置，现在能够获得GZipStream，但我不知道如何将流存储到目录中。不幸的是， System.IO.Compression.ZipFile.ExtractToDirectory（）方法中的ZipFile对象在核心框架中不存在：/。

With that configuration in the project.json I'm now able to get a GZipStream but I have no idea how to store that stream to a directory. Unfortunately the ZipFile object in System.IO.Compression.ZipFile.ExtractToDirectory() method doesn't exsists in the core framework :/.

更新：

我现在以这种方式包括了它，并将其从整体依赖项中删除：

I now included it that way and removed it from the overall dependencies:

"frameworks": {
"dnx451": {
  "dependencies": {
    "System.IO.Compression.ZipFile": "4.0.1-beta-23516"
  }
},
"dnxcore50": {
  "dependencies": {
    "System.IO.Compression.ZipFile": "4.0.1-beta-23516"
  }
}

何时我使用可正常运行的内核运行该应用程序，但使用.net framework 4.6运行该应用程序，在运行时因以下错误而崩溃：

When I run the application using core it works as expected, but running it with the .net framework 4.6 I crashes with the following exeception during runtime:

n处理时发生未处理的异常

n unhandled exception occurred while processing the request.

An unhandled exception occurred while processing the request.
FileNotFoundException: Could not load file or assembly 'System.IO.Compression.ZipFile, Version=4.0.1.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.

推荐答案

在project.json中需要的依赖项如下

The dependencies you require in your project.json are as follows.

"frameworks": {
    "net451": {
      "frameworkAssemblies": {
        "System.IO.Compression": "4.0.0.0",
        "System.IO.Compression.FileSystem":  "4.0.0.0"
      }
    },
    "dnxcore50": {
      "dependencies": {
        "System.IO.Compression.ZipFile": "4.0.1-beta-23516"
      }
    }
  },

project.json根目录中的依赖项适用于与所有您正在使用的运行时。

The dependenices in the root of project.json are for any packages that work with all runtimes you are using.

.net运行时中的frameworkAssemblies与您在基于csproj的普通项目中添加的引用相同。如果不确定要添加什么，可以在此处找到程序集。 https://msdn.microsoft.com/zh-我们/library/mt472912(v=vs.110).aspx 。

The frameworkAssemblies in the .net runtime are the same references you would add in a normal csproj based project. You can find the assemblies here if you are not sure what to add. https://msdn.microsoft.com/en-us/library/mt472912(v=vs.110).aspx. You would use the dependencies section here for any net specific references.

当涉及到dnxcore50时，依赖项引用直接来自nuget，但是您可以使用intellisense来找到它们。

When it comes to dnxcore50 the dependencies references come straight from nuget but you can use the intellisense to find these.
