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

AConsoleApp，Version=1.0.0.0，Culture=neutral，PublicKeyToken=null ConsoleApp.Demo
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:\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();
}
}输出
ApplicationName Binary Serialize --- ApplicationId 1001
