As you've noted, Marshal::Copy (and .NET in general), is not const-safe.

However, the usual C and C++ functions are. You can write either:

array^ data_array =gcnew array(dataSize);
pin_ptr data_array_start = &data_array[0];
memcpy(data_array_start, data, dataSize);

or to avoid pinning:

array^ data_array =gcnew array(dataSize);
for( int i = 0; i < data_array->Length; ++i )
    data_array[i] = data[i];
