我可以在不使用COM的情况下直接使用C ++在.NET中制作DLL文件吗 [英] Can i use, C++ made DLL files in .NET directly without using COM

问题描述

假设，如果我有一个在C ++中创建的DLL文件，没有使用COM

我可以直接在.NET中加载吗?

或COM是必需的??

如果我可以直接加载它，怎么办?

suppose, if i have a DLL file that i created in C++ WITHOUT using COM

Can i load it directly in .NET??

or COM is required???

if i can load it directly, then how??

推荐答案

不，不需要COM.是的，您可以在.NET应用程序中加载导出的本机DLL函数，并通过 P/Invoke平台调用服务使用它们.

请参阅:

No, COM is not required. Yes, you can load exported native DLL functions in your .NET application and use them using Platform Invocation Services, P/Invoke.

Please see:

An alternative approach is using C++/CLI. You can create a mixed-mode (managed+unmanaged) C++/CLI DLL. You can mix C++ with C++/CLI and wrap all native calls to your native DLL into .NET C++/CLI "ref" classes. The obtained executable can be used like a regular .NET assembly and referenced by your C# assembly.
