C#中类的序列化和反序列化

说明：本文演示将类序列化后写入记事本并从记事本读取反序列化为对象
1.首先创建一个类,同时类必须标识为Serializable,如下:

[Serializable]
public class Region
{
    public String _id { get; set; }
    public String region_id { get; set; }
    public String region_name { get; set; }
    public String parent_region_id { get; set; }
}

2.序列化代码如下

//定义对象
Region region = new Region()
{
    region_name = "ABCD"
};
byte[] bytes;
//序列化并写入内存流
using (MemoryStream ms = new MemoryStream())
{
    IFormatter formatter = new BinaryFormatter(); 
    //序列化
    formatter.Serialize(ms, region); 
    bytes=ms.GetBuffer();
}
//将内存流写入文件
FileStream fs = new FileStream("aa.txt", FileMode.OpenOrCreate);
fs.Write(bytes, 0, bytes.Length);
fs.Close();

3.反序列化代码如下

//将文件读取为文件流并写入byte数组
FileStream fs = new FileStream("aa.txt", FileMode.OpenOrCreate);
var length=Convert.ToInt32(fs.Length);
byte[] bytes = new byte[length];
fs.Read(bytes, 0, length);
//将byte数组写入内存流
using (MemoryStream ms = new MemoryStream(bytes))
{
    IFormatter formatter = new BinaryFormatter();
    //反序列化后强制转换
    Region region = (Region)formatter.Deserialize(ms);
    Console.WriteLine(region.region_name);
}

说明:经本人测试没有任何问题
