无法序列化成员....因为它是一个接口

Question

我一直有这个问题,一直把头发拉过来.我有以下错误:

异常详细信息:System.NotSupportedException:无法序列化类型为System.Collections.Generic.IList`1 [[HannaPrintsDataAccess.CustomerAddress,HannaPrintsDataAccess,Version = 1.0.0.0,Culture = neutral,PublicKeyToken = null]]的成员HannaPrintsDataAccess.Customer.CustomerAddresses,因为它是一个界面.

来源错误:

第196行:客户客户= OperationsManager.Instance.CustomerService.GetCustomer(7); 第197行:第198行:字符串xml = OperationsManager.Instance.CustomerService.GetCustomerAddressesXml(CustomerAddress.FindAll()); 第199行:第200行:订单订单= OperationsManager.Instance.OrderService.CreateOrderFromCart(xml);

源文件:c:\ HostingSpaces\greetwus\galadavetiye.com\wwwroot\HannaPrints\HannaPrints\WebUI\CreateGreetingCard.aspx.cs行:198

堆栈跟踪:

[NotSupportedException:无法序列化类型System.Collections.Generic.IList`1 [[HannaPrintsDataAccess.CustomerAddress,HannaPrintsDataAccess,Version = 1.0.0.0,Culture = neutral,PublicKeyToken = null]]的成员HannaPrintsDataAccess.Customer.CustomerAddresses,因为它是一个接口]

[InvalidOperationException:无法序列化'System.Collections.Generic.IList`1 [[HannaPrintsDataAccess.CustomerAddress,HannaPrintsDataAccess,Version = 1.0.0.0,Culture = neutral,PublicKeyToken = null]]'类型的成员'HannaPrintsDataAccess.Customer.CustomerAddresses',有关更多详细信息,请参阅内部异常.] System.Xml.Serialization.StructModel.CheckSupportedMember(TypeDesc typeDesc,MemberInfo成员,类型类型)+889917 System.Xml.Serialization.StructModel.GetPropertyModel(PropertyInfo propertyInfo)+132 ...... ..

我已经将我的所有IList更改为List's以查看它是否可以执行任何操作,但事实上,在进行这些更改之后它甚至没有花费一秒钟加载,我猜测因为错误甚至在它到达该部分之前发生.我检查了我的远程文件,看它是否正确上传,确实如此.

这是代码:

using System;
using System.Collections.Generic; 
using Castle.ActiveRecord;
namespace HannaPrintsDataAccess { 
    public partial class Customer { 
        private IList _customerAddresses;


        public CustomerAddress GetPrimaryCustomerAddress()
        {
            foreach (CustomerAddress address in _customerAddresses)
            {
                if (address.IsPrimary)
                    return address;
            }
            return null;
        }


        [HasMany(typeof(CustomerAddress), ColumnKey = "CustomerId", Table = "Customer")]
        public virtual IList<CustomerAddress> CustomerAddresses
        {
            get
            {
                return this._customerAddresses;
            }
            set
            {
                this._customerAddresses = value;
            }
        }
    }
}

激活此代码时会发生错误:

protected void orderButton_Click(object sender, EventArgs e)
{
    Customer customer = OperationsManager.Instance.CustomerService.GetCustomer(7);

    string xml = OperationsManager.Instance.CustomerService.GetCustomerAddressesXml(CustomerAddress.FindAll());

    Order order = OperationsManager.Instance.OrderService.CreateOrderFromCart(xml);
    OperationsManager.Instance.CartService.MoveCart("MyDesigns");

    Response.Redirect("~/Customer/PayByCreditCard.aspx?orderGuid=" + order.OrderGuid);
}

CustomerAddress类:

using System.IO;
using System.Xml.Serialization;
using Castle.ActiveRecord;


namespace HannaPrintsDataAccess
{
public partial class CustomerAddress
{
    public string ToXml()
    {
        XmlSerializer serializer = new XmlSerializer(GetType());
        MemoryStream memoryStream = new MemoryStream();
        serializer.Serialize(memoryStream, this);
        memoryStream.Seek(0, SeekOrigin.Begin);
        return new StreamReader(memoryStream).ReadToEnd();
    }

    [BelongsTo("CustomerId")]
    public virtual Customer Customer { get; set; }
}
}

在您发布的代码中,类型CustomerAddresses为IList<CustomerAdress>.那是一个界面.与错误消息一样,您无法序列化接口.
