将List <object>传递给WCF服务始终为null </object>

Question

我有下面的对象：

[DataContract]
    public class MyListofProducts
    {
        [DataMember]
        public List<Product> Products { get; set; }

    }
[DataContract]
    public class Product
    {
        [DataMember]
        public string Alias { get; set; }
        [DataMember]
        public bool IsNew { get; set; }
        [DataMember]
        public bool IsVisible { get; set; }
        [DataMember]
        public int MinOrder { get; set; }
        [DataMember]
        public string OrderUnit { get; set; }
        [DataMember]
        public string TaxClass { get; set; }
        [DataMember]
        public float Weight { get; set; }
        [DataMember]
        public List<Item> AvailabilityComment { get; set; }
        [DataMember]
        public List<Item> Name { get; set; }
        [DataMember]
        public List<Item> Keywords { get; set; }
        [DataMember]
        public List<Item> Description { get; set; }
        [DataMember]
        public List<Item> LongDescription { get; set; }
        [DataMember]
        public List<ProductPrice> ProductPrices { get; set; }
        public List<Attribute> Attributes { get; set; }

    }

我的WCF运营合同如下：

public bool Create(MyListofProducts products)
            {
                var productConroller = new ProductController();
                return productConroller.Create(products);
            }

当我创建.net客户端时生成的肥皂请求如下（全部工作）：

    <s:Body>

但是当传递下面的Soap请求时，它总是得到null：

我不明白为什么WCF在第二种情况下无法序列化对象列表？

所有我发现差异低于位。

<product xmlns:a="http://schemas.datacontract.org/2004/07/IFSConnect.Models" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">

任何建议都将受到赞赏。

[ServiceContract(Namespace = "http://BiggroupServices.IFSConnect/")]
public interface IProductService
    {
        [OperationContract]
        bool Create(MyListofProducts product);
