Question

We are using protobuf-net (and love it!). We now have a protocontract-decorated child class derived from a parent base class, which IS NOT protocontract-decorated.

We are trying to get the child class to serialize/deserialize some of the parent class’ fields.

public abstract class TableServiceEntity
{
    public virtual string PartitionKey { get; set; }
    public virtual string RowKey { get; set; }
    public DateTime Timestamp { get; set; }
}

[ProtoContract]
public class IndicatorStreamIndex : TableServiceEntity
{
    // protomember properties
}

How can we get IndicatorStreamIndex to serialize/deserialize PartitionKey, RowKey, and Timestamp?

Best,
Mike

This can be configured pretty easily in v2, using RuntimeTypeModel to tweak the configuration at runtime:

// this should only be done once per AppDomain, usually at app startup
RuntimeTypeModel.Default.Add(typeof (IndicatorStreamIndex), true)
    .Add("PartitionKey", "RowKey", "Timestamp");

// then when needed:
var obj = new IndicatorStreamIndex
{
    RowKey = "abc",
    PartitionKey = "def",
    Timestamp = DateTime.Today
};
var clone = Serializer.DeepClone(obj);
Console.WriteLine(clone.RowKey); // "abc"
Console.WriteLine(clone.PartitionKey); // "def"
Console.WriteLine(clone.Timestamp); // 13/02/2012
