Question

我使用NuGet Package Manager在我的项目中添加了Log4Net，它显示了我的系统上安装的版本2.3。

这是我的配置条目：

  <configSections>
    <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>

然后在这里引用此文件

  <log4net configSource="Log4Net.config" />
  <system.serviceModel>

但是当我运行网站时。显示以下异常。

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)

我已经看到dll存在于bin文件夹中，但显示的是版本1.2.13.0。

如何更改装配版本？

似乎您的解决方案中的某个项目或者某些第三方dll已使用不同版本的log4net构建。您可以在所有项目中更新对log4net的引用（使用第三方dll也无济于事），或者您可以将程序集重定向设置添加到web.config（app.config），它将指定版本的log4net重定向到新的。 / p>

将此部分放在配置元素

下的任何位置的web.config（app.config）中

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentAssembly>
            <assemblyIdentity name="log4net"
                          publicKeyToken="1b44e1d426115821"
                          culture="neutral" />
            <bindingRedirect oldVersion="1.2.10.0"
                         newVersion="1.2.13.0"/>
        </dependentAssembly>
    </assemblyBinding>
</runtime>

无法加载文件或程序集'log4net，Version = 1.2.10.0，Culture = neutral，PublicKeyToken = 1b44e1d426115821'
