Question

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。

这样做之后，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。

怎么了？为什么这样的冲突存在，因为这是SharpZipLib的唯一安装？

我将构建日志设置为详细，但未考虑在内。

编辑：

这是定义依赖项的web.config文件：

Answer 1

事实证明，web.config中的此定义是问题所在：

  <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。

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。
