Using Properties in Your C++ Classes

Properties are pseudo-data members of your classes. They are accessed just like public data members but in reality they are functions within the class.

#using <mscorlib.dll>

using namespace System;
using namespace System::IO;


__gc class PropClass
{
    int m_x;
    int m_y;
    int m_z;

public:
    PropClass() : m_y(19762), m_z(3860)
    {
    }
    // read / write properties for a data member __property int get_x(){ return m_x;} __property void set_x(int v){ m_x=v;} // read only properties for a data member __property ...
