问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . I have recently inherited a program written in Managed C++ from some guy who just retired. After spending some time digging through it, I can honestly say that at least 95% of it belongs on thedailywtf. However, I am now tasked with modifying it and porting it over to a language I'm comfortable with. The program

问题 Is there a way to add assembly attributes to a Managed C++ assembly? In a typical C# project, there is usually a line of code in the AssemblyInfo.cs file like the following one: [assembly: AssemblyTitle("Some Assembly")] I have a private assembly attribute that I want to add (not one of the version attributes that could be added through a resource file), and I am not sure if this is possible. 回答1: It is possible - the easy way is to add an AssemblyInfo.cpp file and put: #include attributes.h

问题 I've got a legacy managed c++ dll, and I need to call some function which is returning a managed type. For dllexports without managed types, this is easy, I just define my static c(++) function in a header like this: extern "C" { __declspec(dllexport) int __cdecl InitSystem(); } But now the static c(++) function should return a managed type, and here I got a problem. If I try (for example): extern "C" { __declspec(dllexport) System::Collections::Generic::List<System::String^>^ __cdecl

问题 A.dll is a native c++ dll, B.dll is a managed c++ dll. A.dll depends on B.dll, so when load A.dll, B.dll is loaded automatically, but after A.dll is unloaded, B.dll is still loaded. Only A.dll depends on B.dll, why B.dll can't be unloaded? How to unload the managed c++ dll? I'm using vs2010. Thanks 回答1: You cannot unload a managed assembly once it is loaded by the CLR. The only way is to kill the AppDomain. 来源： https://stackoverflow.com/questions/7697621/how-to-unload-managed-c-dll

问题 What is exactly the difference between the "old" Managed C++ and the "new" C++/CLI? 回答1: Managed C++ is the version in VS2002 and VS2003. It had race conditions and other serious bugs, as well as being confusing. It's no longer supported. In VS2005, Microsoft introduced C++/CLI, which has also been accepted as an ISO standard. It's also supported in VS2008 and the upcoming VS2010. Both of them had the same goal, which is to create .NET assemblies using the C++ language. The syntax is
