Question

I have problem with deserialization using protobuf-net.

I have the following class:

[ProtoContract]
public class CrazyList : List<string>
{
    [ProtoMember(1)]
    private readonly string _foo;

    public CrazyList(string foo)
    {
        _foo = foo;
    }

    public CrazyList(){}

    public new void Add(string item)
    {
        Console.Write(item + foo); // Problem is here!

        base.Add(item);
    }

}

And use it like this:

var list = new CrazyList("world!");
list.Add("Hello ");

using (var ms = new MemoryStream())
{
    Serializer.Serialize(ms, list);

    ms.Position = 0;

    var listDS = Serializer.Deserialize<CrazyList>(ms);
    listDS.Add("Goodbye ");
}

The method Add is firing before the _foo field deserialization is completed.

How I can solve this problem?

Answer 1

you need to use this for the CrazList attribut;

[ProtoBuf.ProtoContract(IgnoreListHandling=true)]
