System.IO.Compression.FileSystem.dll在C＃程序中 [英] System.IO.Compression.FileSystem.dll in c# program

问题描述

我想使用dll >

命名空间：System.IO.Compression

程序集： System.IO.Compression.FileSystem（在System.IO.Compression.FileSystem.dll中）

所以你需要包含的命名空间是 System.IO.Compression 不是 System.IO.Compression.FileSystem 。从部分使用语句取出 FileSystem 部分，它将解决您的问题。

如果有人投我票，因为OP说问题是没有找到dll。我认为OP没有使用正确的单词选择，如果问题确实是无法找到DLL，那么原始屏幕截图没有的程序集名称会有一个感叹号。

请参阅下面的原始图片

将我的屏幕截图与我创建的屏幕截图进行比较，如果找不到DLL，请注意感叹号，原始屏幕截图没有。

I' like to use the dll System.IO.Compression.FileSystem.dll in my project

the .net framework version is 4.5 and the os is 64. The problem is that the dll is not found. What is the solution?

解决方案

The namespace is not the same as the dll name (assembly name). from the MSDN page you linked

Namespace: System.IO.Compression
Assembly: System.IO.Compression.FileSystem (in System.IO.Compression.FileSystem.dll)

So the namespace you need to include is System.IO.Compression not System.IO.Compression.FileSystem. Take off the FileSystem part from your using statement and it will solve your problem.

If people are down-voting me because the OP said "The problem is that the dll is not found." I think the OP is not using the correct word choice, if the problem really was that the DLL could not be found there would be a exclamation point by the assembly name which the original screenshot does not have

Compare that to my screenshot I created that would show up if the DLL really was not found, note the exclamation point I have that the original screenshot does not.
