Question

我有两个派生自通用基类的类。

[Serializable()]
[XmlInclude(typeof(User))]
[XmlInclude(typeof(File))]
public class BaseEntity<T>
{
    private long id;

    [XmlAttribute(AttributeName = "id")]
    public virtual long ID
    {
        get { return this.id; }
        set { this.id = value; }
    }
}

[Serializable()]
public class User : BaseEntity<User>
{
    private string userName;
    private string sharedDirectory;
    private bool connected;

    [XmlAttribute(AttributeName = "UserName")]
    public virtual string UserName 
    {
        get { return this.userName; }
        set { this.userName = value; } 
    }

    [XmlAttribute(AttributeName = "SharedDirectory")]
    public virtual string SharedDirectory
    {
        get { return this.sharedDirectory; }
        set { this.sharedDirectory = value; }
    }

    [XmlAttribute(AttributeName = "IsConnected")]
    public virtual bool IsConnected
    {
        get { return this.connected; }
        set { this.connected = value; }
    }
}

[Serializable()]
public class File : BaseEntity<File>
{
    private string name;
    private User user;

    [XmlAttribute(AttributeName = "Name")]
    public virtual string Name
    {
        get { return this.name; }
        set { this.name = value; }
    }

    [XmlElement(ElementName = "User", Type = typeof(User))]
    public virtual User User
    {
        get { return this.user; }
        set { this.user = value; }
    }
}

我有一个返回文件列表（列表）的Web服务（不是WCF服务）。当我调用该服务时，该方法已执行但序列化过程失败。这是我得到的例外情况：

System.Web.Services.Protocols.SoapException：服务器无法处理请求。 ---＆GT; System.InvalidOperationException：生成XML文档时出错。 ---＆GT; System.InvalidOperationException：不期望Castle.Proxies.UserProxy类型。使用XmlInclude或SoapInclude属性指定静态未知的类型。\ n在Microsoft的Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationWriter1.Write4_User（String n，String ns，User o，Boolean isNullable，Boolean needType）\ n。在Microsoft的Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationWriter1.Write7_GetFilesByNameResponse（Object [] p）\ n的Xml.Serialization.GeneratedAssembly.XmlSerializationWriter1.Write6_File（String n，String ns，File o，Boolean isNullable，Boolean needType）\ n。 System.Xml.Serialization.XmlSerializer.Serialize（XmlWriter xmlWriter，Object o，XmlSerializerNamespaces namespaces，String encodingStyle，String id）中的Xml.Serialization.GeneratedAssembly.ArrayOfObjectSerializer1.Serialize（Object objectToSerialize，XmlSerializationWriter writer）\ n System.Xml.Serialization.XmlSerializer.Serialize（XmlWriter xmlWriter，Object o，XmlSerializerNamespaces namespaces，String）中内部异常堆栈跟踪--- \ n在System.Web.Services.Protocols.SoapServerProtocol.WriteReturns（Object [] returnValues，Stream outputStream）\ n中的encodingStyle，String id）\ n在System.Web.Services.Protocols.WebServiceHandler.WriteReturns（Object [] returnValues）\ n在System.Web.Services.Protocols.WebServiceHandler.Invoke（）\ n ---内部异常堆栈跟踪结束---

谁知道为什么？

因为我使用了lazy = true，当我序列化我的对象时，序列化程序试图序列化不允许的Proxy对象。当我将映射更改为lazy = false时，它工作正常！

序列化自定义对象
