序列化和反序列化

 1　　 using System.Runtime.Serialization.Formatters.Binary;//其他引用略
 2 　　[Serializable]//必须的特性
    class A
    {
        public string name;
    }

    class Program
    {
        static void Main(string[] args)
        {
            using (var stream = File.Open(@"F:data.my", FileMode.Create, FileAccess.ReadWrite))//扩展名随意
            {
                var data = new BinaryFormatter();
                data.Serialize(stream, new A() { name = "123" });//序列化
            }

            using (var stream = File.Open(@"F:data.my", FileMode.Open, FileAccess.ReadWrite))
            {
                var da = (new BinaryFormatter()).Deserialize(stream) as A;//反序列化
                Console.WriteLine(da.name);
            }
        }
    }

会在F盘下生成一个datm.my的文件
