Question

I am just drawing a blank here. Have a class that I want read only properties on the class but an admin type function that can update a property.

public class Group : Object, INotifyPropertyChanged
{   // this is read only admin is via UserGroupAdmin
    public event PropertyChangedEventHandler PropertyChanged;
    private void NotifyPropertyChanged(String info)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(info));
        }
    } 

    public Int16 ID { get; private set; }
    public string Name { get; private set; }
    public override bool Equals(Object obj)
        {
            //Check for null and compare run-time types.
            if (obj == null || !(obj is Group)) return false;
            Group item = (Group)obj;
            return (ID == item.ID);
        }

    public override int GetHashCode() { return (int)ID; }
    public Group(Int16 id, string name)
    { ID = id; Name = name;  }
 }

What I would like is an admin type function

public group ReviseGroupName (Group group, string revisedName)
{
   // write revised name to SQL
   // revise group.name
   // return revised group
}

The SQL part I know. What I considered was just creating a new group with the same ID and hashcode and returning it.

If the Admin is a nested class in Group you can set the private property in the function:

public class Group
{
    public string Name { get; private set; }

    public class Admin
    {
        public Group ReviseGroupName (Group group, string revisedName)
        {
            group.Name = revisedName;
            return group;
        }
    }
}
