将一个对象转换为不可读的二进制格式称为二进制序列化。

将二进制格式转换回可读的格式称为反序列化？

要在C#中实现二进制序列化，我们必须使用库System.Runtime.Serialization.Formatters.Binary Assembly。

创建BinaryFormatter类的对象，并在类内部使用serialize方法。

示例

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:TempQuestions.dat", FileMode.Create);
      BinaryFormatter formatter = new BinaryFormatter();
      formatter.Serialize(fileStream, sample);
      Console.ReadKey();
   }
}

输出

示例

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:TempQuestions.dat ", FileMode.Open);
      BinaryFormatter formatter = new BinaryFormatter();
      Demo deserializedSampledemo = (Demo)formatter.Deserialize(fileStream);
      Console.WriteLine($"ApplicationName { deserializedSampledemo.ApplicationName} --- ApplicationId       { deserializedSampledemo.ApplicationId}");
      Console.ReadKey();
   }
}

输出

ApplicationName Binary Serialize --- ApplicationId 1001
