以log4net为例，分为两种情况

1.不同version，相同publicKeyToken

在bin里放较新版本的dll

并在web|app.config的<configuration>下放

<runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="log4net" publicKeyToken="1b44e1d426115821" culture="neutral" />
                <bindingRedirect oldVersion="0.0.0.0-1.2.10.0"
                                 newVersion="1.2.11.0"/>
            </dependentAssembly>
        </assemblyBinding>
    </runtime>

2.不同version，不同publicKeyToken

在bin里创建不同版本的文件夹，并放入对应版本的dll

并在

web.config的<configuration>下放

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="log4net" publicKeyToken="681549d62126b7b8" />
        <codeBase version="1.2.9.0" href="bin/log4net1.2.9.0/log4net1.2.9.0.dll" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="log4net" publicKeyToken="1b44e1d426115821" />
          <codeBase version="1.2.10.0" href="bin/log4net1.2.10.0/log4net1.2.10.0.dll" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="log4net" publicKeyToken="669e0ddf0bb1aa2a" />
          <codeBase version="1.2.11.0" href="bin/log4net1.2.11.0/log4net1.2.11.0.dll" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

或者

app.config的<configuration>下放

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="log4net" publicKeyToken="681549d62126b7b8" />
        <codeBase version="1.2.9.0" href="log4net1.2.9.0/log4net1.2.9.0.dll" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="log4net" publicKeyToken="1b44e1d426115821" />
          <codeBase version="1.2.10.0" href="log4net1.2.10.0/log4net1.2.10.0.dll" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="log4net" publicKeyToken="669e0ddf0bb1aa2a" />
          <codeBase version="1.2.11.0" href="log4net1.2.11.0/log4net1.2.11.0.dll" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
