我发现了几个与此问题相关的线程，但没有一个解决了我的问题。

我之前一直在我的 ASP.NET 服务中使用 log4net version 1.2.10.0。我已经将它更新到当前版本 log4net v2.0.8.0，由于一些第三方库，我还在我的 web.config 中添加了以下行以支持/重定向旧版本。

<runtime>    
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">      
      <dependentAssembly>
        <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="9.0.0.0" />
      </dependentAssembly>      
      <dependentAssembly>
       <assemblyIdentity name="log4net" publicKeyToken="1b44e1d426115821" culture="neutral" />
      <bindingRedirect oldVersion="0.0.0.0-1.2.10.0" newVersion="2.0.8.0" />      
      </dependentAssembly>    
    </assemblyBinding>
</runtime>

我也对这些Messages一头雾水 内部异常: ((System.IO.FileLoadException)ex.InnerException.InnerException).Message

Could not load file or assembly 'log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=1b44e1d426115821' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

异常信息:

可能是以下几行指向 FusionLog 中的问题

WRN: Comparing the assembly name resulted in the mismatch: PUBLIC KEY TOKEN ERR: Failed to complete setup of assembly (hr = 0x80131040). Probing terminated

建议

我是否需要将两个 .dll 都放在/bin 文件夹中，

堆栈跟踪

更新

根据 Ciprian Lipan 在评论中的建议，我在 .csproj 中找到了这个条目，其中 PublicKeyToken 与我的 web.config 不同我复制了这个 token 并在配置中替换了它，只得到了异常消息，内部异常消失了。波纹管是 .csproj 中的条目

<Reference Include="log4net, Version=2.0.8.0, Culture=neutral, PublicKeyToken=669e0ddf0bb1aa2a, processorArchitecture=MSIL">
      <HintPath>packages\log4net.2.0.8\lib\net45-full\log4net.dll</HintPath>
      <Private>True</Private>
</Reference>

异常

Could not load file or assembly 'log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=**1b44e1d426115821**' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

但是我用 .csproj 中的新 token 更改了配置中的 token

最佳答案

Apache 决定更改他们的公钥，arg! similar post here 中有一个解决方案.

或者您可以使用旧公钥 token 恢复对旧 1.2.10.0 版本的引用。 nuget log4net 1.2.10.0

关于c# - 无法加载文件或程序集 'log4net, Version=2.0.8.0, Culture=neutral, PublicKeyToken=1b44e1d426115821' 或其依赖项之一，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42851718/
