In the .net CLR Object is the base for all class objects, but not basic types (eg int, float etc). How can I use basic types like Object? Ie Like Boost.Variant ?
Eg like :-
object intValue( int(27) );
if (intValue is Int32)
...
object varArray[3];
varArray[0] = float(3.141593);
varArray[1] = int(-1005);
varArray[2] = string("String");
object
, via boxing, is the effective (root) base-class of all .NET types. That should work fine - you just need to use is
or GetType()
to check the types...
object[] varArray = new object[3];
varArray[0] = 3.141593F;
varArray[1] = -1005;
varArray[2] = "String";
Since you mentioned you're in C++/CLI, you should be able to do:
array<Object^>^ varArray = gcnew array<Object^>(3);
varArray[0] = 3.141593;
varArray[1] = -1005;
varARray[2] = "String";
double val = *reinterpret_cast<double^>(varArray[0]);
object varArray[3] = new object[3];
varArray[0] = 3.141593;
varArray[1] = -1005;
varArray[2] = "String";
Thanks for the boxing answer. I need to box my return value, eg
Object ^ createFromString(String ^ value)
{
Int32 i( Convert::ToInt32(value) );
return static_cast< Object ^ >(i);
}
I need to box the return value by casting to an Object pointer. Intuitive! :)
And retrieve as:
void writeValue(Object ^ value, BinaryWriter ^ strm)
{
Int32 i( *dynamic_cast< Int32 ^ >(value) );
strm->Write(i);
}
