Best way to expose protected fields

Question

I have a base class like this:

 public class BaseModalCommand
 {

    protected object m_commandArgument;
    protected int m_commandID;
    protected int m_         


        

Answer 1

Basically, FxCop recommends that you should do

private object m_commandArgument;

protected object CommandArgument
{
   get { return m_commandArgument; }
   set { m_commandArgument =value}
}

This is based on OO encapsulation rule- (One of three OO rules). You may want to check the value before assigning, and you want to ensure this is not directly manipulated by the derived class.
