Comment : procéder à une conversion entre System::Guid et _GUID
L'exemple de code suivant indique comment effectuer une conversion entre Guid et _GUID.
Exemple
// convert_guids.cpp
// compile with: /clr
#include <windows.h>
#include <stdio.h>
using namespace System;
Guid FromGUID( _GUID& guid ) {
return Guid( guid.Data1, guid.Data2, guid.Data3,
guid.Data4[ 0 ], guid.Data4[ 1 ],
guid.Data4[ 2 ], guid.Data4[ 3 ],
guid.Data4[ 4 ], guid.Data4[ 5 ],
guid.Data4[ 6 ], guid.Data4[ 7 ] );
}
_GUID ToGUID( Guid& guid ) {
array<Byte>^ guidData = guid.ToByteArray();
pin_ptr<Byte> data = &(guidData[ 0 ]);
return *(_GUID *)data;
}
int main() {
_GUID ng = {0x11111111,0x2222,0x3333,0x44,0x55,0x55,0x55,0x55,0x55,0x55,0x55};
Guid mg;
Console::WriteLine( (mg = FromGUID( ng )).ToString() );
_GUID ng2 = ToGUID( mg );
printf_s( "%x-%x-%x-", ng2.Data1, ng2.Data2, ng2.Data3 );
for (int i = 0 ; i < 8 ; i++) {
if (i == 2)
printf_s("-");
printf_s("%x", ng2.Data4[i]);
}
printf_s("\n");
}
