Problem creating managed classes and namespaces in C++/CLI
I am having problems creating a managed class with namespace in C++/CLI.
I would like to do the following:
#pragma once
#include "abc.h"
#ifdef _MANAGED
#using <system.dll>
using namespace System;
using namespace System::IO;
using namespace System::Collections::Generic;
using namespace System::Globalization;
#endif
namespace Animals
{
public ref class Pets
{
Pets::Pets(){}
};
}
I have a couple different problems:
A) When I place this code into the .cpp file, it compiles fine. However, it appears the namespaces are not working as expected (see this question I created: Namespace not recognized in C++/CLI) The only answer listed says I must declare the classes/namespaces in the header file. But this is a problem because..
B) The compiler complains about public ref class Pets when it is placed in the header file. It says there must be a syntax error.
intellisense error:
expected a declaration
other errors:
'{' : missing function header (old-style formal list?)
syntax error: 'public'
I can't seem to find any great C++/CLI examples that show both the header and the cpp file.
So my question is: How can I make both the managed class and namespace work as expected? (ie what am I doing wrong?)
Please let me know if I need to include any more information.
Thanks in advance for your time and patience :)
在头文件中应该有前向声明。
// abc.h
#pragma once
namespace Animals
{
public ref class Pets
{
Pets(); // forward declaration
// Pets::Pets is redundant and wrong, because you are inside
// the class Pets
};
}
// abc.cpp
#include "abc.h"
#ifdef _MANAGED
#using <system.dll>
using namespace System;
using namespace System::IO;
using namespace System::Collections::Generic;
using namespace System::Globalization;
#endif
namespace Animals
{
Pets::Pets() {} // implementation
// Now Pets::Pets() is right, because you dont write the class... wrapper again.
}
