C#提供三种序列化的方法，与此有关的三个类分别是：BinarySerialize、SoapSerialize、XmlSerialize

以二进制的序列化和反序列化为例，先创建一个实体类Product。

1  [Serializable] 2     public class Product 3     { 4         public int id; 5         public string name; 6         public double price; 7         [NonSerialized] 8         public string notes; 9         public Product(int Id, string Name, double Price, string Notes) 10         {11             id = Id;12             name = Name;13             price = Price;14             notes = Notes;15         }16 17         public override string ToString()18         {19             return string.Format("This product's id is{0},name is{1},price is{2}.", id, name, price, notes);20         }

重新ToString方法以便打印实体。

给实体赋值，在进行的序列化和反序列化之前进行都进行文件的压缩与解压，用的是GZipStream

List
     
       productList = new List
      
        { new Product(1, "orange", 1.0, "sales"),                 new Product(2, "Apple", 2.0, "cheap") };            foreach(Product product in productList)            {                Console.WriteLine(product);            }            Console.WriteLine("Please select your file");            FileStream fs = new FileStream("Product.ini", FileMode.Create, FileAccess.ReadWrite);            GZipStream gzCompressed = new GZipStream(fs, CompressionMode.Compress);            try            {                IFormatter serialize = new BinaryFormatter();                serialize.Serialize(gzCompressed, productList);                gzCompressed.Close();                FileStream fsRead = new FileStream("Product.ini", FileMode.Open, FileAccess.Read);                GZipStream gzDecompressed = new GZipStream(fsRead, CompressionMode.Decompress);                List
       
         deProductList = serialize.Deserialize(gzDecompressed) as List
        
         ;                gzDecompressed.Close();                foreach (Product product in deProductList)                {                    Console.WriteLine(product);                }            }            catch (SerializationException se)            {                Console.WriteLine(se.Message);            }            catch(IOException io)             {                Console.WriteLine(io.ToString());            }            Console.ReadKey();
