Anchor missing for sibling nested objects

[RKeelan]

The code below serializes an OuterClass that contains a list of two InnerClasses. Both InnerClasses have a reference to the same array. In the serialization, the first InnerClass's Arrayhas no anchor, but the second InnerClass's Array nevertheless uses an alias (which is presumably supposed to refer to the first Array).

I tested this with SharpYaml 1.9.0.

Serialization:

!Yaml.OuterClass
InnerObjects:
  - Array:
      - 1
      - 2
  - Array: *o3

Code:

using NUnit.Framework;
using SharpYaml.Serialization;
using System.Collections.Generic;

namespace Yaml {
    [TestFixture]
    public class Test {
        [Test]
        public void Anchor()
        {
            var array = new int[] { 1, 2 };
            var expected = new OuterClass() {
                InnerObjects = new List<InnerClass>()
            };
            for (int i = 0; i < 2; i++) {
                var inner = new InnerClass {
                    Array = array
                };
                expected.InnerObjects.Add(inner);
            }

            var settings = new SerializerSettings() { EmitDefaultValues = true, EmitAlias = true };
            settings.RegisterAssembly(typeof(OuterClass).Assembly);
            var serializer = new Serializer(settings);

            string serialString = serializer.Serialize(expected);
           // This line throws an exception
            var actual = serializer.Deserialize(serialString);
        }

    }
    public class OuterClass {
        public List<InnerClass> InnerObjects { get; set; }
    }
    public class InnerClass {
        public int[] Array { get; set; }
    }
}

Thanks. Seems you were the first one to try to serialize a same array instance 🙂
This should be fixed by commit dcd5e74

That's great, thank you!
