我之前在ASP.NET服务中使用过log4net 1.2.10.0版.我已将其更新为当前版本的log4net v2.0.8.0,由于某些第三方库,我还在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>

我也对这些消息感到困惑
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)

例外消息：

Could not load file or assembly ‘log4net,Version=2.0.8.0,PublicKeyToken=1b44e1d426115821′ or one of its
dependencies. The located assembly’s manifest definition does not

可能以下几行指向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

我需要将.dll放在/ bin文件夹中,

更新

在Ciprian Lipan的评论建议之后,我在.csproj中找到了这个条目,其中PublicKeyToken与我的web.config不同我复制了这个标记并在config中替换并且只获得了异常消息,内部异常消失了. bellow是进入.csproj的

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

例外

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

但是我在配置中使用.csproj中找到的新令牌
