本文介绍如何使用ProtoBuf的.Net社区版本进行序列化和反序列化操作，包括基本类、包含关系及继承关系的序列化示例。通过控制台程序演示了Person类及其Address子类、BaseClass及其派生类DerivedClass的序列化与反序列化过程。

本示例使用ProtoBuf的.Net社区版本：https://github.com/mgravell/protobuf-net。创建控制台程序，从NuGet中搜索并安装作者为Marc Gravell的版本。

1、GIthub示例（包含关系）

    [ProtoContract]
    class Person
    {
        [ProtoMember(1)]
        public int Id { get; set; }
        [ProtoMember(2)]
        public string Name { get; set; }
        [ProtoMember(3)]
        public Address Address { get; set; }
    }
    [ProtoContract]
    class Address
    {
        [ProtoMember(1)]
        public string Line1 { get; set; }
        [ProtoMember(2)]
        public string Line2 { get; set; }
    }

2、继承示例

    [ProtoContract]
    [ProtoInclude(100, typeof(DerivedClass))]
    public class BaseClass
    {
        [ProtoMember(1)]
        public int Id { get; set; }
    }
    [ProtoContract]
    public class DerivedClass : BaseClass
    {
        [ProtoMember(1)]
        public string Name { get; set; }
        [ProtoMember(2)]
        public int Age { get; set; }
    }

3、序列化/反序列化

    public class ProtoHelper
    {
        public static byte[] Serialize<T>(T t)
        {
            var stream = new MemoryStream();
            Serializer.Serialize<T>(stream, t);
            var bytes = stream.ToArray();
            stream.Close();
            stream.Dispose();
            return bytes;
        }

        public static T Deserialize<T>(byte[] bytes)
        {
            var stream = new MemoryStream(bytes);
            var t = Serializer.Deserialize<T>(stream);
            stream.Close();
            stream.Dispose();
            return t;
        }
    }

4、测试类

    public class TestProtoBuf
    {
        private byte[] _bufferPerson;
        private byte[] _bufferDerivedClass;

        public void Serialize()
        {
            var person = new Person()
            {
                Id = 101,
                Name = "ZhangSan",
                Address = new Address()
                {
                    Line1 = "ZhengZhou",
                    Line2 = "Kexue Rd."
                }
            };
            Console.WriteLine("Before Person Serialize: {0}, {1}, {2}, {3}",
                person.Id, person.Name, person.Address.Line1, person.Address.Line2);
            _bufferPerson = ProtoHelper.Serialize(person);

            var derivedClass = new DerivedClass()
            {
                Id = 12,
                Name = "test class",
                Age = 23
            };
            Console.WriteLine();
            Console.WriteLine("Before DerivedClass Serialize: {0}, {1}, {2}",
                derivedClass.Id, derivedClass.Name, derivedClass.Age);
            _bufferDerivedClass = ProtoHelper.Serialize(derivedClass);
        }

        public void Deserialize()
        {
            if (_bufferPerson != null)
            {
                var person = ProtoHelper.Deserialize<Person>(_bufferPerson);
                Console.WriteLine();
                Console.WriteLine("After Person Serialize: {0}, {1}, {2}, {3}",
                    person.Id, person.Name, person.Address.Line1, person.Address.Line2);
            }

            if (_bufferDerivedClass != null)
            {
                var derivedClass = ProtoHelper.Deserialize<DerivedClass>(_bufferDerivedClass);
                Console.WriteLine();
                Console.WriteLine("After DerivedClass Serialize: {0}, {1}, {2}",
                    derivedClass.Id, derivedClass.Name, derivedClass.Age);
            }
        }
    }

5、测试代码

var testProtoBuf = new TestProtoBuf();
testProtoBuf.Serialize();
testProtoBuf.Deserialize();
