序列化和反序列化

参考使用 类：

using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary

class ConfigFileFactory
    {
        public static void SaveConfigurature()
        {
            IFormatter formatter = new BinaryFormatter();
            if (!Directory.Exists(FilePath.Instance.XmlConfigFilePath))
            {
                Directory.CreateDirectory(FilePath.Instance.XmlConfigFilePath); //文件路径

            }
            Stream stream = new FileStream(FilePath.Instance.XmlFullFileName, FileMode.OpenOrCreate, FileAccess.Write, FileShare.None);

            formatter.Serialize(stream, XXXXCLASS); //被序列化的类
            stream.Close();
        }

        public static SerializableSettingViewModel GetConfiguration()
        {
            Stream stream2 = new FileStream(FilePath.Instance.XmlFullFileName, FileMode.Open, FileAccess.Read, FileShare.None);
            IFormatter formatter = new BinaryFormatter();
            XXXXCLASS viewModel =  (XXXXCLASS)formatter.Deserialize(stream2); //反序列化的类
            stream2.Close();
            return viewModel;
        }
    }

其中 类中要标记为 可序列化 [Serializable]
