关于对象序列化的一个有关问题,

关于对象序列化的一个问题,急..
有一个对象
  [System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "2.0.50727.3038")]
  [System.SerializableAttribute()]
  [System.Diagnostics.DebuggerStepThroughAttribute()]
  [System.ComponentModel.DesignerCategoryAttribute("code")]
  [System.Xml.Serialization.XmlTypeAttribute(Namespace="http://marketing.ews.yahooapis.com/V4")]
  public partial class TargetingAttribute {
   
  private TargetingAttributeDescriptor[] targetsField;
   
  /// <remarks/>
  [System.Xml.Serialization.XmlArrayAttribute(IsNullable=true)]
  public TargetingAttributeDescriptor[] targets {
  get {
  return this.targetsField;
  }
  set {
  this.targetsField = value;
  }
  }
  }

  子对象
  [System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "2.0.50727.3038")]
  [System.SerializableAttribute()]
  [System.Diagnostics.DebuggerStepThroughAttribute()]
  [System.ComponentModel.DesignerCategoryAttribute("code")]
  [System.Xml.Serialization.XmlTypeAttribute(Namespace="http://marketing.ews.yahooapis.com/V4")]
  public partial class TargetingAttributeDescriptor {
   
  private long idField;
   
  private bool idFieldSpecified;
   
  private System.Nullable<TargetingAttributeType> typeField;
   
  private bool typeFieldSpecified;
   
  /// <remarks/>
  public long ID {
  get {
  return this.idField;
  }
  set {
  this.idField = value;
  }
  }
   
  /// <remarks/>
  [System.Xml.Serialization.XmlIgnoreAttribute()]
  public bool IDSpecified {
  get {
  return this.idFieldSpecified;
  }
  set {
  this.idFieldSpecified = value;
  }
  }
   
  /// <remarks/>
  [System.Xml.Serialization.XmlElementAttribute(IsNullable=true)]
  public System.Nullable<TargetingAttributeType> type {
  get {
  return this.typeField;
  }
  set {
  this.typeField = value;
  }
  }
   
  /// <remarks/>
  [System.Xml.Serialization.XmlIgnoreAttribute()]
  public bool typeSpecified {
  get {
  return this.typeFieldSpecified;
  }
  set {
  this.typeFieldSpecified = value;
  }
  }
  }

我将TargetingAttribute 进行xml序列化后,得到的结果是
<?xml version="1.0" encoding="utf-16"?>
<TargetingAttribute xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <targets xmlns="http://marketing.ews.yahooapis.com/V4">
  <TargetingAttributeDescriptor />
  </targets>
</TargetingAttribute>

我确定TargetingAttributeDescriptor 对象是有值得,但是序列化出来的TargetingAttributeDescriptor 对象的属性都没了..

请问是哪个环节出问题了呢...谢谢!


[解决办法]

C# code

    [System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "2.0.50727.3038")]    [System.SerializableAttribute()]    [System.Diagnostics.DebuggerStepThroughAttribute()]    [System.ComponentModel.DesignerCategoryAttribute("code")]    [System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://marketing.ews.yahooapis.com/V4")]    public partial class TargetingAttributeDescriptor    {        private long idField;        private bool idFieldSpecified;        private System.Nullable<TargetingAttributeType> typeField;        private bool typeFieldSpecified;        /// <remarks/>         [XmlAttribute()]        public long TargetingAttributeID  //你这里原来写的ID,应该是和XML里的某个元素重复了，无法显示。下面的Type也一样,我改成            {                  //TargetingAttributeType            get            {                return this.idField;            }            set            {                this.idField = value;            }        }        /// <remarks/>         [XmlAttribute()]        public bool IDSpecified        {            get.Calculate();
