1. System::String 轉換到 const wchar_t*

const wchar_t* ToUnmanagedUnicode( System::String^ str )
{
pin_ptr<const WCHAR> nativeString1 = PtrToStringChars( str );
return (const wchar_t*)nativeString1;
}

2. const wchar_t* / const char* 轉換到 System::String

const wchar_t* p= L"hello";
System::String( p ).ToString();

?

3. C++數值類型轉CLR數值類型

int a;
System::Int32 b = System::Int32( a );

4. HWND 轉為IWin32Window

public ref class WindowWrapper : System::Windows::Forms::IWin32Window
{

public: WindowWrapper(IntPtr handle)
{
_hwnd = handle;
}

public:
property IntPtr Handle
{
virtual IntPtr get(void){return _hwnd;};
};

private: IntPtr _hwnd;
};

HWND nativehwnd;
IWin32Window^ w = gcnew Managed::WindowWrapper( System::IntPtr( nativehwnd ) );
