CSharp学习笔记 （一）序列化类实例

XmlSerializer, DataContractSerializer 和 BinaryFormatter区别与用法分析：http://www.cnblogs.com/nankezhishi/archive/2012/05/12/serializationcompare.html

1. DataContractSerializer ：所有类均可实例化，不需要加可序列化关键词

（1）序列化：

try
{
fs = new FileStream(文件名, FileMode.Create);
ser = new DataContractSerializer(typeof(类名));
ser.WriteObject(fs, 类实例变量);
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(类名));
类名 类实例名 = (类名)ser.ReadObject(reader, true);
psidentify = new 类名(类实例名);    //array to List
reader.Close();
fs.Close();

2. BinaryFormatter：类定义前需加关键词[Serializable]，文件小，内容不易解读

（1）序列化：

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