C#中4种深拷贝方法介绍

作者:互联网

1:利用反射实现

public static T DeepCopy<T>(T obj)

{   //如果是字符串或值类型则直接返回   if (obj is string || obj.GetType().IsValueType) return obj;     object retval = Activator.CreateInstance(obj.GetType());   FieldInfo[] fields = obj.GetType().GetFields(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Static);   foreach (FieldInfo field in fields)   {     try { field.SetValue(retval, DeepCopy(field.GetValue(obj))); }     catch { }   }   return (T)retval; }   2:利用xml序列化和反序列化实现 public T DeepCopy<T>(T obj)     {       object retval;       using (MemoryStream ms = new MemoryStream())       {         XmlSerializer xml = new XmlSerializer(typeof(T));         xml.Serialize(ms, obj);         ms.Seek(0, SeekOrigin.Begin);         retval = xml.Deserialize(ms);         ms.Close();       }       return (T)retval;     }   利用二进制序列化和反序列化实现   public static T DeepCopy<T>(T obj) {   object retval;   using (MemoryStream ms = new MemoryStream())   {     BinaryFormatter bf = new BinaryFormatter();     //序列化成流     bf.Serialize(ms, obj);     ms.Seek(0, SeekOrigin.Begin);     //反序列化成对象     retval = bf.Deserialize(ms);     ms.Close();   }   return (T)retval; }
