How to convert 'System::Object __gc *' to 'float array '

[viks]

Hi guys

I need little help here .
I want to convert 'System::Object __gc * array ' to 'float array'

Lets say I have object Reader with method Send ,it returns a variant
that contains a one-dimensional array of float value .

I m trying to do something like this.

float analogdata[5];

analogdata = Reader->Send ;

When I try this I get following error.
error C2440: '=' : cannot convert from 'System::Object __gc *' to
''float [5]'
Please help me out here :(

thanks

If I remember correctly you can not assign to an array, nor may you
return an array. You can however assign to a pointer an you can also
return a pointer. In other words try 'flot* analogdata;'.

This is not C++ but C++/CLI, the Microsoft hybrid language between C++
and C#. Try to ask in a newsgroup dedicated to C++/CLI.

The error message makes it clear that the context is not C++. While the
question may very well turn out to be pure C++, in such a case it's
usually a waste of time to play detective in order to find some possible
C++ content. So even though your question turned out to actually be
meaningful also in C++ (invalid assignment to array), by including
non-C++ context you've basically cut yourself off from answers from most
C++ experts, and you /do not know/ whether answers based on pure C++ are
valid, because the rules in an extended language may be different.
