普通版：
public static object CloneObject( object obj ) { using ( MemoryStream memStream = new MemoryStream( ) ) { BinaryFormatter binaryFormatter = new BinaryFormatter( null , new StreamingContext( StreamingContextStates.Clone ) ); binaryFormatter.Serialize( memStream , obj ); memStream.Seek( 0 , SeekOrigin.Begin ); return binaryFormatter.Deserialize( memStream ); } }
泛型版：
public static T Clone<T>(T obj) { T ret = default(T); if (obj != null) { XmlSerializer cloner = new XmlSerializer(typeof(T)); MemoryStream stream = new MemoryStream(); cloner.Serialize(stream, obj); stream.Seek(0, SeekOrigin.Begin); ret = (T)cloner.Deserialize(stream); } return ret; }
注意：如果某个类报提示错误：XXX类无法序列化，则要在类名上加上[Serializable]
