Question

以下是我在制作此加载项时遇到的一些警告：

    Warning 1   
    Processing COM reference "" from path "C:\Windows\system32\stdole32.tlb". The type library importer could not convert the signature for the member 'DISPPARAMS.rgvarg'.

    Warning 2   
    Processing COM reference "" from path "C:\Windows\system32\stdole32.tlb". The type library importer could not convert the signature for the member 'DISPPARAMS.rgdispidNamedArgs'.

    Warning 3   
    Processing COM reference "VBA" from path "C:\Windows\system32\VEN2232.OLB". Type library importer has encountered an interface not derived from IUnknown: '_HiddenInterface'.

这个加载项正常运行，但我想知道这些警告的含义。当我查看它们时，我看到的是processing COM references和converting来自system32文件夹的某些文件存在一些问题。我对此一无所知......

有人可以看看他们并给我一个更具体的解释，也许可以为他们提供一些解决方案。我会非常感激每一个信息。

这些错误没什么大不了的。它只是意味着无法自动导入COM类型库中的某些类型。从Visual Studio构建过程（或后端使用的MSBuild任务），我认为您不能删除这些错误。它们由.NET内部类型库导入程序生成，没有可以传递的标记。

你可以做的是在你的其他构建操作之前使用Tlbimp.exe (Type Library Importer)工具创建所需的互操作程序集，并引用它们而不是让IDE完成工作。该工具的最新版本了解silence开关。

没有开关：

使用静音开关（多次出现）：
