本文實例講述了C#自界說序列化ISerializable的完成辦法。分享給年夜家供年夜家參考。詳細完成辦法以下：

[Serializable]
public class BaseObject
{
  [OptionalField]
  private string _str = "I am BaseObject";
}
[Serializable]
public class TestObject : BaseObject, ISerializable
{
  int a;
  string strName = "";
  Color c = Color.Red;
  DataTable _dtColors = null;
  [OptionalField]
  ArrayList list = new ArrayList();
  [OptionalField]
  List<int> list1 = new List<int>();
  [OptionalField]
  Dictionary<int, string> dic = new Dictionary<int, string>();
  //當完成ISerializable接口時，假如該結構函數不存在，則會激發一個SerializationException異常
  //該特征表現，該辦法只許可序列化器調
  [SecurityPermissionAttribute(SecurityAction.Demand, SerializationFormatter = true)]
  protected TestObject(SerializationInfo info, StreamingContext context)
  {
   #region 假如基類也完成了ISerializable接口，則序列化器會主動挪用基類的該結構函數，就不須要本段代碼
   Type basetype = this.GetType().BaseType;
   MemberInfo[] mi = FormatterServices.GetSerializableMembers(basetype, context);
   for (int i = 0; i < mi.Length; i++)
   {
    //因為AddValue不克不及添減輕名值，為了不子類變量名與基類變量名雷同，將基類序列化的變量名加上基類類名
    FieldInfo fi = (FieldInfo)mi[0];
    object objValue = info.GetValue(basetype.FullName + "+" + fi.Name, fi.FieldType);
    fi.SetValue(this, objValue);
   }
   #endregion
   a = info.GetInt32("a");
   strName = info.GetString("strName");
   c = (Color)info.GetValue("c", typeof(Color));
   _dtColors = (DataTable)info.GetValue("_dtColors", typeof(DataTable));
   list = (ArrayList)info.GetValue("list", typeof(ArrayList));
   list1 = (List<int>)info.GetValue("list1", typeof(List<int>));
   dic = (Dictionary<int, string>)info.GetValue("dic", typeof(Dictionary<int, string>));
  }
  public TestObject()
  {
   a = 100;
   strName = "daps";
   InitColorTable();
   list1.Add(10);
   list1.Add(20);  
  }
  #region ISerializable 成員
  [SecurityPermissionAttribute(SecurityAction.Demand, SerializationFormatter =true)]
  void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context)
  {
   info.AddValue("a", a);
   info.AddValue("strName", strName);
   info.AddValue("c", c);
   info.AddValue("_dtColors", _dtColors);
   info.AddValue("list", list);
   info.AddValue("list1", list1);
   info.AddValue("dic", dic);
   Type basetype = this.GetType().BaseType;
   MemberInfo[] mi = FormatterServices.GetSerializableMembers(basetype, context);
   for (int i = 0; i < mi.Length; i++)
   {
    //因為AddValue不克不及添減輕名值，為了不子類變量名與基類變量名雷同，將基類序列化的變量名加上基類類名
    info.AddValue(basetype.FullName + "+" + mi[i].Name, ((FieldInfo)mi[i]).GetValue(this));
   }
  }
  #endregion
}
