Question

我的原生程序是temp / A / prog.exe。我正在使用C ++ / CLI中的Assembly :: Load（）在temp / B / LoadAssem.dll上加载.Net程序集。但是assem.dll引用了位于temp / C中的dynAssem.dll。我编写了如下配置文件：

<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>

但是绑定失败了，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.

我理解这个目录布局不是.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（参见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>

但它出现（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较高的文件夹。

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。

.NET使用应用程序配置文件来加载另一个程序集引用的程序集
