CSharp學習筆記 （一）序列化類實例

XmlSerializer, DataContractSerializer 和 BinaryFormatter區別與用法分析：http://www.cnblogs.com/nankezhishi/archive/2012/05/12/serializationcompare.html

1. DataContractSerializer ：所有類均可實例化，不需要加可序列化關鍵詞

（1）序列化：

            try
            {
                fs = new FileStream(文件名, FileMode.Create);
                ser = new DataContractSerializer(typeof(類名));
                ser.WriteObject(fs, 類實例變量);
                fs.Close();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

（2）反序列化：

            FileStream fs = new FileStream(文件名, FileMode.Open);
            XmlDictionaryReader reader = XmlDictionaryReader.CreateTextReader(fs, new XmlDictionaryReaderQuotas());
            DataContractSerializer ser = new DataContractSerializer(typeof(類名));
            類名 類實例名 = (類名)ser.ReadObject(reader, true);
            psidentify = new 類名(類實例名);    //array to List
            reader.Close();
            fs.Close();

2. BinaryFormatter：類定義前需加關鍵詞[Serializable]，文件小，內容不易解讀

（1）序列化：

                fs = new FileStream(文件名, FileMode.Create);
                try
                {
                    formatter.Serialize(fs, 類實例名);
                }
                catch (SerializationException e)
                {
                    Console.WriteLine("Failed to serialize. Reason: " + e.Message);
                    throw;
                }
                finally
                {
                    fs.Close();
                }

（2）反序列化：

                fs = new FileStream(文件名, FileMode.Open);
                try
                {
                    類實例名 = (類名)formatter.Deserialize(fs);
                }
                catch (SerializationException e)
                {
                    Console.WriteLine("Failed to deserialize. Reason: " + e.Message);
                    throw;
                }
                finally
                {
                    fs.Close();
                }
