问题描述
我在MVC 5项目中正在使用NPOI.当我通过Nuget安装它时，我已经安装了SharpLib 0.86，因为它是一个依赖项.
I am using NPOI in my MVC 5 project. When I installed it via Nuget, I have installed SharpLib 0.86 because it is a dependency.
执行此操作后，NPOI会生成一个0字节的文件.当我构建解决方案时，此错误出现在错误列表中:
After doing this, NPOI generates a 0 bytes file. When I build the solution, this error appears in error list:
Found conflicts between different versions of "ICSharpCode.SharpZipLib" that could not be resolved. These reference conflicts are listed in the build log when log verbosity is set to detailed.
我确定NPOI无法正常工作.
I am sure NPOI does not work properly cause of this.
怎么了?为什么这样的冲突存在，因为这是SharpZipLib的唯一安装?
What's the matter? Why such a conflict exists since this is the only installation of SharpZipLib?
我将构建日志设置为详细，但未考虑在内.
I set the build log as detailed, but it is not taken into account.
这是定义依赖项的web.config文件:
This is the web.config file where dependencies are defined:

推荐答案
事实证明，web.config中的此定义是问题所在:
It turned out that this definition in web.config was the problem:
<dependentAssembly>
<assemblyIdentity name="ICSharpCode.SharpZipLib" publicKeyToken="1b03e6acf1164f73" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-1.0.0.999" newVersion="1.0.0.999" />
</dependentAssembly>
我意识到定义的版本是1.0.0.999，而不是实际使用的0.86.0.518.我不知道何时添加该定义.也许是由于在降级前后安装了SharpZipLib 1，NuGet软件包管理器未修改定义.
I realized that version defined was 1.0.0.999, instead of 0.86.0.518, which is actually used. I don't know when that definition was added. Maybe it was due because SharpZipLib 1 was installed before and after downgrade, definition was not modified by NuGet package manager.
我手动将其更改为:
<dependentAssembly>
<assemblyIdentity name="ICSharpCode.SharpZipLib" publicKeyToken="1b03e6acf1164f73" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-0.86.0.518" newVersion="0.86.0.518" />
</dependentAssembly>
错误消失了.
此外，我的猜测是正确的:NPOI也开始工作.
Furthermore, my guess was correct: NPOI started working too.
