Windows Phone：如何在SQLite-net中排除列/属性？

例如

[Table]
public class MyClass
{
    // this property is written to the database
    privatE int _ItemId;

    [column(IsprimaryKey = true,IsDbGenerated = true,DbType = "int nOT NULL Identity",CanBeNull = false,AutoSync = AutoSync.onInsert)]
    public int ItemId
    {
        get
        {
            return _ItemId;
        }
        set
        {
            _ItemId = value;
        }
    }

    // abstract class. obvIoUsly this just an example. the real code checks for 11. =)
    // under sqlite,it looks like this will get stored in the db?
    public bool IsItemIdSeven
    {
        get{ return _ItemId == 7; }
    }
}

是否可以从sqlite-net中的类定义中排除属性？我不能使用扩展,因为UI绑定使用了一些这些属性.
