c# - DebuggerTypeProxy クラスの DebuggerDisplay 属性

Question

[DebuggerDisplay("{OneLineAddress}")] をデバッガ プロキシのクラスで使用すると、動作しないようです。私が間違っていることはありますか？または、元のクラスにコードを追加せずにこれを回避する方法はありますか?

[DebuggerTypeProxy(typeof(AddressProxy))]
class Address
{
    public int Number { get; set; }
    public string Street { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    public int Zip { get; set; }

    public Address(int number, string street, string city, string state, int zip)
    {
        Number = number;
        Street = street;
        City = city;
        State = state;
        Zip = zip;
    }

    [DebuggerDisplay("{OneLineAddress}")] // doesn't seem to work on proxy
    private class AddressProxy
    {
        [DebuggerBrowsableAttribute(DebuggerBrowsableState.Never)]
        private Address _internalAddress;

        public AddressProxy(Address internalAddress)
        {
            _internalAddress = internalAddress;
        }

        public string OneLineAddress
        {
            get { return _internalAddress.Number + " " + _internalAddress.Street + " " + _internalAddress.City + " " + _internalAddress.State + " " + _internalAddress.Zip; }
        }
    }
}
