XML序列化问题

我不断收到此错误：XML序列化问题

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.

我似乎无法弄清楚这一点，我敢肯定它只是一些配置，需要我们拿到的这款之前因为改变代码，据说它工作正常，但我们不知道为什么我们得到这个错误。如果任何人都可以提供帮助，那会很棒。谢谢！！！

UPDATE 我试图改变IList中列出，但它不会做任何事情。这里是我的类与客户地址：

Customer类:::使用System.Collections.Generic

using System;

; 使用Castle.ActiveRecord;

命名空间HannaPrintsDataAccess { 公共部分类客户 { 私人的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; 
     } 
    } 
}

}

下面是使用的System.Xml.Serialization客户地址类::::

using System.IO;

; 使用Castle.ActiveRecord;

命名空间HannaPrintsDataAccess { 公共部分类CustomerAddress { 公共toxml用于字符串（） { XmlSerializer的串行=新的XmlSerializer（的GetType（））; MemoryStream memoryStream = new MemoryStream（）; serializer.Serialize（memoryStream，this）; memoryStream.Seek（0，SeekOrigin.Begin）; 返回新的StreamReader（memoryStream）.ReadToEnd（）; }

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

}再次

感谢您的帮助

由于错误消息明确告诉您XmlSerializer无法序列化接口。

你可能有：

public List<CustomerAddress> CustomerAddresses { get; set; }

您更改为：

public IList<CustomerAddress> CustomerAddresses { get; set; }

不再起作用。

嘿，我试了这个，它没有工作，我更新了我的问题，两个类的代码 – anthonypliu 2010-09-02 18:55:35

你可以把

[System.Xml.Serialization.XmlElement(Type = typeof(List<HannaPrintsDataAccess.CustomerAddress>))]

的财产

HannaPrintsDataAccess

假设日e成员实际上是一个实例List<T>

基本上，该属性需要支持Xml序列化继承。也就是说，如果一个属性的类型是IList的，实例是List<T>类型（自IList继承）的，则需要该属性添加到属性指定List<T>.

您不能使用'XmlInclude'属性修饰属性。 – 2010-09-02 18:39:32

认识到并纠正了。 – Jeff 2010-09-02 18:43:03

这也不起作用。 – 2010-09-02 18:47:28

该错误消息似乎非常清楚对我说：

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.

尝试更换的HannaPrintsDataAccess.Customer.CustomerAddresses的类型，这是目前IList<CustomerAddress>，与混凝土类型（例如List<CustomerAddress>）代替的接口。

嗨，我试过这个解决方案，但它没有工作，我做了一个编辑我的问题与更多信息 – anthonypliu 2010-09-02 19:00:25

接口属性仍然是public，所以串行器仍然会尝试序列化它（和崩溃）。

放在这样的接口属性的XmlIgnore属性：

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

您List实现也搞砸了。添加这个声明下方您IList<CustomerAddress>财产申报：

public List<CustomerAddress> CustomerAddresses 
{ 
    get 
    { 
     return (List<CustomerAddress>)this._customerAddresses; 
    } 
    set 
    { 
     this._customerAddresses = value; 
    } 
}

HTH ...

附：为了将来的参考，请记住所有公共属性对于xml序列化程序都是可见的，并且将尝试序列化它们。确保将XmlIgnore属性放在不应该序列化的属性上。

嘿，我试了这个，它仍然给我相同的确切的错误，我不不明白为什么，因为我仔细检查了我的远程文件以确保所做的更改通过了，但它仍然有相同的错误消息，即使我将其更改为List而不是IList。 – anthonypliu 2010-09-02 19:31:46
