.NET远程处理（Remoting）与WCF的性能对比

用TCP信道时，.NET远程处理默认的序列化器是System.Runtime.Serialization.Formatters.Binary.BinaryFormatter。WCF是用SOAP传送消息的，即格式是XML。可以设置XML的编码方式，选择编码为文本或二进制数据。下面测试用BinaryFormatter和WCF的序列化器序列化同一个对象时，哪一个产生的二进制流最短。
 
class Program 
   { 
       static void Main(string[] args) 
       { 
           Customer customer = new Customer { Age = 30, FirstName = "Gqq", LastName = "Nb" }; 
 
 
           using (FileStream stream1 = new FileStream(@"B:\binaryFormatter.bin", FileMode.Create)) 
           { 
               BinaryFormatter binFormatter = new BinaryFormatter(); 
               binFormatter.Serialize(stream1, customer); 
           } 
 
           using (FileStream stream2 = new FileStream(@"B:\xmlFormatter.bin", FileMode.Create)) 
           { 
               var serializer = new DataContractSerializer(typeof(Customer)); 
               XmlDictionaryWriter binaryWriter = XmlDictionaryWriter.CreateBinaryWriter(stream2); 
               serializer.WriteObject(binaryWriter, customer); 
               binaryWriter.Close(); 
           } 
       } 
   }

           get { return fn; } 
           set { fn = value; }
