 protobuf-net是Google的protobuf的dotNet实现，目前支持Mono,SilverLight,WCF,WP7 etc。

官方地址：http://code.google.com/p/protobuf-net/

下来我们构建一个简单的示例程序，

1.在官方地址下载最新的类库（目前最新的是：protobuf-net v2 beta r404.zip） 

 2.建立一个Console Application

3.添加类库：protobuf-net.dll到我们的应用程序。

4.示例代码如下：

namespace ProtoBuf_NET
{
    class Program
    {
        static void Main(string[] args)
        {
            string dataDir = Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, "Data");
            string fileName = Path.Combine(dataDir, "Person.txt");
            if(!Directory.Exists(dataDir))
            {
                Directory.CreateDirectory(dataDir);
            }
            //Initialize
            var person = new Person
            {
                Id = 12345,
                Name = "Fred",
                Address = new Address
                {
                    Line1 = "Flat 1",
                    Line2 = "The Meadows"
                }
            };
            //Serializing Data
            using (var file = File.Open(fileName, FileMode.OpenOrCreate, FileAccess.ReadWrite))
            {
                Serializer.Serialize<Person>(file, person);
            }
            //Deserializing Data
            Person newPerson;
            using (var file = File.OpenRead(fileName))
            {
                newPerson = Serializer.Deserialize<Person>(file);
            }
            Console.WriteLine("Name: "+newPerson.Name
                +Environment.NewLine+"Line1:"+newPerson.Address.Line1
                +Environment.NewLine+"Line2:"+newPerson.Address.Line2);
            Console.Read();
        }
    }
}

如果要支持WCF，那么我们就需要添加一个behaviorExtensions

具体如下：

<behaviors>
      <endpointBehaviors>
        <behavior name="protoEndpointBehavior">
          <protobuf/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <extensions>
      <behaviorExtensions>
        <add name="protobuf" type="ProtoBuf.ServiceModel.ProtoBehaviorExtension, protobuf-net, Version=2.0.0.280, Culture=neutral, PublicKeyToken=257b51d87d2e4d67"/>
      </behaviorExtensions>
    </extensions>
  </system.serviceModel>

在客户端和服务端都加上这个ExtensionBehavior

Client：

<client>
         <endpoint address="http://localhost:33545/Service1.svc" binding="wsHttpBinding"
             bindingConfiguration="WSHttpBinding_IService1" contract="ServiceReference1.IService1"
             name="WSHttpBinding_IService1" behaviorConfiguration="protoEndpointBehavior">

             <identity>
                 <dns value="localhost" />
             </identity>
         </endpoint>
     </client>

Server：

<service>
<endpoint address="" binding="wsHttpBinding" contract="TestWcfDto.IService1" behaviorConfiguration="protoEndpointBehavior">                
   <identity>
      <dns value="localhost"/>
   </identity>
</endpoint>
</service>
