什么是C#中的二进制序列化和反序列化以及如何在C#中实现二进制序列化？

Serialize an Object to Binary
[Serializable]
public class Demo {
   public string ApplicationName { get; set; } = "Binary Serialize";
   public int ApplicationId { get; set; } = 1001;
}
class Program {
   static void Main()    {
      Demo sample = new Demo();
      FileStream fileStream = new FileStream(@"C:\Temp\Questions.dat", FileMode.Create);
      BinaryFormatter formatter = new BinaryFormatter();
      formatter.Serialize(fileStream, sample);
      Console.ReadKey();
   }
}

Converting back from Binary to Object
[Serializable]
public class Demo {
   public string ApplicationName { get; set; }
   public int ApplicationId { get; set; }
}
class Program {
   static void Main()    {
      FileStream fileStream = new FileStream(@"C:\Temp\Questions.dat ", FileMode.Open);
      BinaryFormatter formatter = new BinaryFormatter();
      Demo deserializedSampledemo = (Demo)formatter.Deserialize(fileStream);
      Console.WriteLine($"ApplicationName { deserializedSampledemo.ApplicationName} --- ApplicationId       { deserializedSampledemo.ApplicationId}");
      Console.ReadKey();
   }
}

ApplicationName Binary Serialize --- ApplicationId 1001
