BitArray

BitArray class

Array of bits which can be addressed by index. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.

class BitArray : public virtual System::Object,
                 public System::Collections::Generic::ICollection<bool>
