实现深拷贝的一种方法

声明接口：
    

    public interface IClone
    {
        T Clone<T>(T instance) where T : class;
    }

建立CloneManager类实现接口：

public class CloneManager:IClone
    {
        /**//// <summary>
        /// Clones the specified instance.
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="instance">The instance.</param>
        /// <returns>A new instance of an object.</returns>
        T IClone.Clone<T>(T instance)
        {
            XmlSerializer serializer = new XmlSerializer(typeof(T));
            MemoryStream stream = new MemoryStream();
            serializer.Serialize(stream, instance);
            stream.Seek(0, SeekOrigin.Begin);
            return serializer.Deserialize(stream) as T;
        }
    }

实际应用代码：

class Program
    {
        static void Main(string[] args)
        {
            IClone clone = new CloneManager.CloneManager();
            AA ta = new AA();
            ta.aa = 123;
            ta.bb = 234;
            AA tb = clone.Clone<AA>(ta);
            ta.aa = 999;
            ta.bb = 888;
            System.Console.WriteLine(ta.aa);
            System.Console.WriteLine(ta.bb);
            System.Console.WriteLine(tb.aa);
            System.Console.WriteLine(tb.bb);
        }
    }

    public class AA
    {
        public int aa = 0;
        
        public int bb = 0;
    }

简单吧！！
