无法序列成员....因为它是一个接口 [英] Cannot serialize member.... because it is an interface
问题描述
我一直有这个问题，并已拉出我的头发了它。我有跟随着错误：
异常详细信息：System.NotSupportedException：无法序列类型System.Collections.Generic.IList`1 [HannaPrintsDataAccess.CustomerAddress，HannaPrintsDataAccess成员HannaPrintsDataAccess.Customer.CustomerAddresses，版本= 1.0.0.0，文化=中立，公钥=空]，因为它是一个接口
源错误：
196行：客户的客户= OperationsManager.Instance.CustomerService.GetCustomer（7）;
197线：

[出现InvalidOperationException：无法序列类型System.Collections.Generic.IList`1 [HannaPrintsDataAccess.CustomerAddress，HannaPrintsDataAccess，版本= 1.0.0.0的成员HannaPrintsDataAccess.Customer.CustomerAddresses'，文化=中立，公钥=空] ]'，请参见内部异常的更多细节。]
System.Xml.Serialization.StructModel.CheckSupportedMember（TYPEDESC TYPEDESC，成员的MemberInfo，型型）889917
System.Xml.Serialization.StructModel.GetPropertyModel（的PropertyInfo的PropertyInfo）+132 ........我已经改变了我所有的IList对列出的，看看是否会做任何事情，但它没有，事实上，它没有更兼第二使得这些变化之后加载，即时猜测是因为错误发生它到达，即使之前部分。我检查了我的远程文件，看它是否被正确上传，这是
下面是code：
使用系统;
使用System.Collections.Generic;
使用Castle.ActiveRecord;
命名空间HannaPrintsDataAccess {
公共部分类客户{
私人的IList _customerAddresses;
公共CustomerAddress GetPrimaryCustomerAddress（）
{
的foreach（在_customerAddresses CustomerAddress地址）
{
如果（address.IsPrimary）
退货地址;
}
返回null;
}
[的hasMany（typeof运算（CustomerAddress），ColumnKey =客户编号，表=客户）]
公共虚拟的IList＆LT; CustomerAddress＆GT; CustomerAddresses
{
得到
{
返回this._customerAddresses;
}
组
{
this._customerAddresses =价值;
}
}
}
}在此code被激活发生错误：
保护无效orderButton_Click（对象发件人，EventArgs的发送）
{
客户客户= OperationsManager.Instance.CustomerService.GetCustomer（7）; 字符串XML = OperationsManager.Instance.CustomerService.GetCustomerAddressesXml（CustomerAddress.FindAll（））; 订购订购= OperationsManager.Instance.OrderService.CreateOrderFromCart（XML）;
OperationsManager.Instance.CartService.MoveCart（MyDesigns）; 的Response.Redirect（〜/客户/ PayByCreditCard.aspx orderGuid =？+ order.OrderGuid）;
}在CustomerAddress类：
使用System.IO;
使用的System.Xml.Serialization;
使用Castle.ActiveRecord;
命名空间HannaPrintsDataAccess
{
公共部分类CustomerAddress
{
公共toxml用于字符串（）
{
XmlSerializer的序列化=新的XmlSerializer（的GetType（））;
MemoryStream的MemoryStream的=新的MemoryStream（）;
serializer.Serialize（MemoryStream的，这一点）;
memoryStream.Seek（0，SeekOrigin.Begin）;
返回新的StreamReader（的MemoryStream）.ReadToEnd（）;
} [的belongsTo（客户编号）]
公共虚拟客户客户{搞定;组; }
}
}
解决方案在code你贴的类型，
CustomerAddresses是IList的＆LT; CustomerAdress＆GT;。这是一个接口。像错误消息指出，你不能序列化的界面。I have been having this problem and been pulling my hair out over it. I have the followin error:
Exception Details: System.NotSupportedException: Cannot serialize member HannaPrintsDataAccess.Customer.CustomerAddresses of type System.Collections.Generic.IList`1[[HannaPrintsDataAccess.CustomerAddress, HannaPrintsDataAccess, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]] because it is an interface.

I have changed all my IList's to List's to see if that would do anything, but it didnt, infact, it didnt even take a second to load after making those changes, im guessing because the error happens even before it gets to that part. I checked my remote files to see if it was uploading correctly and it was.
Here is the code:
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; } } } }The error happens when this code is activated:
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); }The CustomerAddress class:
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; } } }
解决方案In the code you posted, the type of
CustomerAddressesisIList<CustomerAdress>. That's an interface. Like the error message says, you can't serialize an interface.这篇关于无法序列成员....因为它是一个接口的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
