Calling C# code from C++, but ExecuteInDefaultAppDomain() is too limited

Question

I need to be able to invoke arbitrary C# functions from C++. In-process Interoperability suggests using ICLRRuntimeHost::ExecuteInDefaultAppDomain(), but this only allows me to invoke methods having this format: int method(string arg)

What is the best way to invoke arbitrary C# functions?

Answer 1

Compile your C++ code with the /clr flag. With that, you can call into any .NET code with relative ease.

For example:

#include <tchar.h>
#include <stdio.h>

int _tmain(int argc, _TCHAR* argv[])
{
    System::DateTime now = System::DateTime::Now;
    printf("%d:%d:%d\n", now.Hour, now.Minute, now.Second);

    return 0;
}

Does this count as "C++"? Well, it's obviously not Standard C++ ...
