.net解决程序集版本冲突的方法

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>
