【protobuf】 3.使用protobuf-csharp-port进行序列化和反序列化

使用protobuf-csharp-port进行序列化和反序列化，以AddressBook为例

有关如何获得AddressBook，如何构建ProtoBuf环境，请看protobuf
2.在Unity的C#中引用

一、序列化

1.构建一个AddressBook对象

AddressBook.Builder addressBookBuilder = AddressBook.CreateBuilder();
Person.Builder person = Person.CreateBuilder();
person.Id = 1;
person.Name = "Test";
person.Email = "test@qq.com";
addressBookBuilder.AddPerson(person);
AddressBook addressBook = addressBookBuilder.Build();

2.调用WriteTo进行序列化

MemoryStream stream = new MemoryStream();
addressBook.WriteTo(stream);
byte[] buffer = stream.ToArray();

3.提取方法，传入ProtoBuf对象（即AddressBook对象）及其泛型，得到byte数组

public static byte[] Serialize<TMessage, TBuilder>(TMessage protoBufObj)
where TMessage : GeneratedMessage<TMessage, TBuilder>
where TBuilder : GeneratedBuilder<TMessage, TBuilder>, new()
{
MemoryStream stream = new MemoryStream();
protoBufObj.WriteTo(stream);
return stream.ToArray();
}

调用方法

byte[] buffer = Serialize<AddressBook, AddressBook.Builder>(addressBook);

二、反序列化

1.通过Builder的MergeFrom方法进行反序列化

AddressBook.Builder builder = new AddressBook.Builder();
builder.MergeFrom(buffer);
AddressBook result = builder.Build();

2.提取方法，以序列化后的byte数组为参数，获得ProtoBuf对象

public static TMessage Deserialize<TMessage, TBuilder>(byte[] buffer)
where TMessage : GeneratedMessage<TMessage, TBuilder>
where TBuilder : GeneratedBuilder<TMessage, TBuilder>, new()
{
TBuilder builder = new TBuilder();
builder.MergeFrom(buffer);
return builder.Build() as TMessage;
}

调用方法

AddressBook result = Deserialize<AddressBook, AddressBook.Builder>(buffer);
