I want to hide the base public property(a data member) in my derived class:

class Program
{
    static void Main(string[] args)
    {
        b obj = new b();
        obj.item1 = 4;// should show an error but it doent ???
    }
}

class a
{
    public int item1 {get; set;}
    public int item2 { get; set; }
}

class b : a
{
    new private int item1;
}

class c : a
{

}

i have member as public because i want the member to be inherited in c class , but want to hide the member in b class , how can i do this ?

dont i have an option to selectively inherite the variable i want in my base class ??? thats really bad , i think ms should provide us with an option (may be a modifier) to perform this

Edit:

I found the answer myself (i heard lots of them telling this is not possible in c#, but you can kind of do it)

I am including the code in case it is useful

class Program
{
    static void Main(string[] args)
    {
        b obj = new b();
        obj.item1 = 4; // shows an error  : )
    }
}

class a
{
    public int item1 { get; set; }
    public int item2 { get; set; }
}

class b : a
{
    new public static int item1
    {
        get;
        private set;
    }
}
c#

You can user new modifer.

Sample;

public class Duck
{
    public string Color{get; set;}
    public void Swim() { }
}
public class DonaldDuck : Duck
{
    new public void Swim() 
    { 
        /*you could call in DonaldDuck.Swim  only here but not public for DonaldDuck client.*/ 
    }
}
