发现 "ICSharpCode.SharpZipLib" 的不同版本之间存在无法解决的冲突

Question

我在我的 MVC 5 项目中使用 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。

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：

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 无法正常工作是因为这个原因。

怎么了？为什么存在这样的冲突，因为这是唯一的 SharpZipLib 安装？

我把build log设置的很详细，但是没有考虑进去

编辑：

这是定义依赖项的 web.config 文件：

Answer 1

原来是web.config中的这个定义有问题：

  <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。我不知道这个定义是什么时候添加的。可能是因为降级前后安装了 SharpZipLib 1，NuGet 包管理器没有修改定义。

我手动改成：

  <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 也开始起作用了。
