.NET 使用应用程序配置文件加载另一个程序集引用的程序集

Question

我的原生程序是 temp/A/prog.exe。我在 temp/B/LoadAssem.dll 中使用 C++/CLI 中的 Assembly::Load() 加载 .Net 程序集。但是 assem.dll 引用了位于 temp/C 中的 dynAssem.dll。我编写的配置文件如下：

<configuration>  
   <runtime>  
      <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">  
       <dependentAssembly>  
         <assemblyIdentity name="DynAssem"  
                           publicKeyToken="xxxxx"  
                           culture="neutral" />  
         <codeBase version="0.0.0.0" href="../C/DynAssem.dll"/>  
       </dependentAssembly>        
      </assemblyBinding>  
   </runtime>  
</configuration>

但绑定失败，融合输出如下：

=== Pre-bind state information ===
LOG: DisplayName = dynAssem
 (Partial)
WRN: Partial binding information was supplied for an assembly:
WRN: Assembly Name: dynAssem | Domain ID: 1
WRN: A partial bind occurs when only part of the assembly display name is provided.
WRN: This might result in the binder loading an incorrect assembly.
WRN: It is recommended to provide a fully specified textual identity for the assembly,
WRN: that consists of the simple name, version, culture, and public key token.

LOG: Attempting download of new URL file:///c:/temp/A/dynAssem/dynAssem.EXE.

我了解此目录布局不是 .NET 的首选布局。但是，我需要支持多种其他语言，因此无法更改目录结构和程序集位置。

您可能希望通过 app.config 中的探测元素实现这一点（请参阅 https://docs.microsoft.com/en-us/dotnet/framework/configure-apps/file-schema/runtime/probing-element）

<configuration>  
   <runtime>  
      <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">  
        <probing privatePath="../C/"/>  
       <dependentAssembly>  
         <assemblyIdentity name="DynAssem"  
                           publicKeyToken="xxxxx"  
                           culture="neutral" />  
         <codeBase version="0.0.0.0" href="../C/DynAssem.dll"/>  
       </dependentAssembly>        
      </assemblyBinding>  
   </runtime>  
</configuration>

但似乎（至少根据Probing the assembly from parent directory of the exe）无法探测文件夹层次结构中更高的文件夹。

编辑：

如此处所述 (https://blogs.msdn.microsoft.com/suzcook/2003/05/29/choosing-a-binding-context/)，您可以使用 LoadFrom 从您喜欢的任何路径加载程序集，我没有尝试过，但这可能是您的解决方案。
