1)决定Feed的标题,作者和更新元素的内容

public class AtomMetadataFeedSerializer : ODataFeedSerializer
{
    public AtomMetadataFeedSerializer(IEdmCollectionTypeReference edmType,ODataSerializerProvider serializerProvider)
        : base(edmType,serializerProvider)
    {
    }

    public override ODataFeed CreateODataFeed(IEnumerable FeedInstance,ODataSerializerContext writeContext)
    {
        ODataFeed Feed = base.CreateODataFeed(FeedInstance,writeContext);
        Feed.Atom().Title = new AtomTextConstruct { Kind = AtomTextConstructKind.Text,Text = "My Awesome Feed" };
        return Feed;
    }
}

public class CustomSerializerProvider : DefaultODataSerializerProvider
{
    public override ODataEntrySerializer CreateEdmTypeSerializer(IEdmTypeReference edmType)
    {
        if (edmType.IsCollection() && edmType.AsCollection().ElementType().IsEntity())
        {
            // Feed serializer
            return new AtomMetadataFeedSerializer(edmType.AsCollection(),this);
        }

        return base.CreateEdmTypeSerializer(edmType);
    }
}

并使用注册自定义序列化程序提供程序,

config.Formatters.InsertRange(0,ODataMediaTypeFormatters.Create(new CustomSerializerProvider(),new DefaultODataDeserializerProvider()));

2)自定义编辑链接

public class CustomEntityTypeSerializer : ODataEntityTypeSerializer
{
    public CustomEntityTypeSerializer(IEdmEntityTypeReference edmType,serializerProvider)
    {
    }

    public override ODataEntry CreateEntry(EntityInstanceContext entityInstanceContext,ODataSerializerContext writeContext)
    {
        ODataEntry entry = base.CreateEntry(entityInstanceContext,writeContext);
        if (notProduceEditLinks)
        {
            entry.EditLink = null;
        }

        return entry;
    }
}

public class CustomSerializerProvider : DefaultODataSerializerProvider
{
    public override ODataEntrySerializer CreateEdmTypeSerializer(IEdmTypeReference edmType)
    {
        if (edmType.IsEntity())
        {
            // entity type serializer
            return new CustomEntityTypeSerializer(edmType.AsEntity(),this);
        }

        return base.CreateEdmTypeSerializer(edmType);
    }
}

并如上所述注册自定义序列化程序提供程序.

我们仍然不支持方案3,即别名类型名称和命名空间.
