Hide public property of base class in Child Class

Ajay Patel

Hello,

I have following example.

public class clsMobileDataSharing
{
public DateTime? EventDate { get; set; }
public string Message { get; set; }
public MobileEventName EventName { get; set; }
public int? AgencyID { get; set; }
public string PersonnelPK { get; set; }
}
[Serializable]
public class clsPoliceDataSharing : clsMobileDataSharing
{
public TempEvents EventNameTemp { get; set; }
}

When I create object of Child class then it display base class's "EventName" property. I don't want this.

How to hide base class property in child class ?

One thing you could do to hide the base class's EventName property would be this:

[Serializable]
public class clsPoliceDataSharing : clsMobileDataSharing
{
new public TempEvents EventName { get; set; }
}

However, if you don't want to change the name of the derived class property, then your options are limited.

You could hide the base class's implementation of the EventName with your own. For example:

[Serializable]
public class clsPoliceDataSharing : clsMobileDataSharing
{
public TempEvents EventNameTemp { get; set; }

new public MobileEventName EventName { get { return null; } }
}

Well, even though it's hidden, the base class's EventName property is still inherited and it's underlying field will therefore be serialized when you serialize an object of the derived class.

I assume that the resulting name clash is what is causing the exception.

If you don't want the base class field to be serialized at all, I'd suggest you make the base class serializable but place the NonSerialized attribute on the field:

[Serializable]
public class clsMobileDataSharing
{
public DateTime? EventDate { get; set; }
public string Message { get; set; }

[NonSerialized]
private MobileEventName _eventName;
public MobileEventName EventName
{
get{ return _eventName;}
set{ _eventName = value; }

}

public int? CompanyID { get; set; }
public string UserPK { get; set; }
}

Hello,

Thanks for your reply and it works for compile time but display runtime error

Member clsJailData.EventName of type XSharingWS.JailEvent hides base class member clsMobileDataSharing.EventName of type XSharingWS.MobileEventName. Use XmlElementAttribute or XmlAttributeAttribute to specify a new name.

here is my code :

public class clsMobileDataSharing
    {
        public DateTime? EventDate { get; set; }
        public string Message { get; set; }
        public MobileEventName EventName { get; set; }
        public int? CompanyID { get; set; }
        public string UserPK { get; set; }
    }
    [Serializable]
    public class clsJailData : clsMobileDataSharing
    {
        private JailEvent _JailEvent;

        new public JailEvent EventName
        {
            get
            {
                return _JailEvent;
            }
            set
            {
                _JailEvent = value;
            }
        }

    }

Please give me solution why this happen...
