介绍
WCF(Windows Communication Foundation) - 序列化：本文分别以DataContractSerializer,XmlSerializer,DataContractJsonSerializer,SoapFormatter,BinaryFormatter为例 。


示例
1、服务
DataContractSerializerObject.cs

using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;

 using System.Runtime.Serialization;

 namespace WCF.ServiceLib.Serialization
 {
 /// <summary>
/// 用于演示DataContract序列化的实体类
 /// </summary>
// Namespace-数据契约的命名空间
[DataContract(Namespace = " http://webabcd.cnblogs.com/ " )]
 public class DataContractSerializerObject
 {
 // Name-数据成员的名称
 // Order-数据成员的序列化和反序列化的顺序
[DataMember(Name = " UniqueID " ,Order = 0 )]
 public GuidID { get ; set ;}

[DataMember(Order = 1 )]
 public string Name { get ; set ;}

[DataMember(Order = 2 )]
 public int Age { get ; set ;}

[DataMember(Order = 3 )]
 public DateTimeTime { get ; set ;}
}
}

XmlSerializerObject.cs
using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;

 using System.Runtime.Serialization;
 using System.Xml.Serialization;

 namespace WCF.ServiceLib.Serialization
 {
 /// <summary>
/// 用于演示XML序列化的实体类
 /// </summary>
// Namespace-XML根元素的命名空间
[XmlRoot(Namespace = " http://webabcd.cnblogs.com/ " )]
 public class XmlSerializerObject
 {
 // ElementName-生成的XML元素的名称
 // Order-序列化和反序列化的顺序
[XmlElement(ElementName = " UniqueID " ,Order = 0 )]
 public GuidID { get ; set ;}

[XmlElement(Order = 1 )]
 public string Name { get ; set ;}

[XmlElement(Order = 2 )]
 public int Age { get ; set ;}

[XmlElement(Order = 3 )]
 public DateTimeTime { get ; set ;}
}
}

SoapFormatterObject.cs
using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;

 using System.Runtime.Serialization;
 using System.Xml.Serialization;

 namespace WCF.ServiceLib.Serialization
 {
 /// <summary>
/// 用于演示Soap序列化的实体类
 /// </summary>
[Serializable]
 public class SoapFormatterOjbect
 {
 public GuidID { get ; set ;}
public string Name { get ; set ;}
public int Age { get ; set ;}
public DateTimeTime { get ; set ;}
}
}

BinaryFormatterObject.cs
using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;

 using System.Runtime.Serialization;
 using System.Xml.Serialization;

 namespace WCF.ServiceLib.Serialization
 {
 /// <summary>
/// 用于演示Binary序列化的实体类
 /// </summary>
[Serializable]
 public class BinaryFormatterObject
 {
 public GuidID { get ; set ;}
public string Name { get ; set ;}
public int Age { get ; set ;}
public DateTimeTime { get ; set ;}
}
}

DataContractJsonSerializerObject.cs
using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;

 using System.Runtime.Serialization;

 namespace WCF.ServiceLib.Serialization
 {
 /// <summary>
/// 用于演示JSON序列化的实体类
 /// </summary>
// Namespace-数据契约的命名空间
[DataContract(Namespace = " http://webabcd.cnblogs.com/ " )]
 public class DataContractJsonSerializerObject
 {
 // Name-数据成员的名称
 // Order-数据成员的序列化和反序列化的顺序
[DataMember(Name = " UniqueID " ,Order = 0 )]
 public GuidID { get ; set ;}

[DataMember(Order = 1 )]
 public string Name { get ; set ;}

[DataMember(Order = 2 )]
 public int Age { get ; set ;}

[DataMember(Order = 3 )]
 public DateTimeTime { get ; set ;}
}
}


2、演示
Sample.aspx.cs
using System;
 using System.Collections;
 using System.Configuration;
 using System.Data;
 using System.Linq;
 using System.Web;
 using System.Web.Security;
 using System.Web.UI;
 using System.Web.UI.HtmlControls;
 using System.Web.UI.WebControls;
 using System.Web.UI.WebControls.WebParts;
 using System.Xml.Linq;

 using System.IO;

 using API = WCF.ServiceLib.Serialization;

 public partial class Serialization_Sample:System.Web.UI.Page
 {
 protected void Page_Load( object sender,EventArgse)
 {
 // 演示DataContractSerializer的序列化和反序列化
ShowDataContractSerializer();

 // 演示XmlSerializer的序列化和反序列化
ShowXmlSerializer();

 // 演示SoapFormatter的序列化和反序列化
ShowSoapFormatter();

 // 演示BinaryFormatter的序列化和反序列化
ShowBinaryFormatter();

 // 演示DataContractJsonSerializer的序列化和反序列化
ShowDataContractJsonSerializer();
}

/// <summary>
/// 演示DataContractSerializer的序列化和反序列化
 /// </summary>
void ShowDataContractSerializer()
 {
vardataContractSerializerObject = new API.DataContractSerializerObject {ID = Guid.NewGuid(),Name = " DataContractSerializer " ,Age = 28 ,Time = DateTime.Now} ;

varserializer = new System.Runtime.Serialization.DataContractSerializer( typeof (API.DataContractSerializerObject));

 // 序列化
varms = new MemoryStream();

serializer.WriteObject(ms,dataContractSerializerObject);

ms.Position = 0 ;
varsr = new StreamReader(ms);
varstr = sr.ReadToEnd();
txtDataContractSerializer.Text = str;


 // 反序列化
varbuffer = System.Text.Encoding.UTF8.GetBytes(str);
varms2 = new MemoryStream(buffer);
vardataContractSerializerObject2 = serializer.ReadObject(ms2) as API.DataContractSerializerObject;
lblDataContractSerializer.Text = dataContractSerializerObject2.Name;
}

/// <summary>
/// 演示XmlSerializer的序列化和反序列化
 /// </summary>
void ShowXmlSerializer()
 {
varxmlSerializerObject = new API.XmlSerializerObject {ID = Guid.NewGuid(),Name = " XmlSerializer " ,Time = DateTime.Now} ;

varserializer = new System.Xml.Serialization.XmlSerializer( typeof (API.XmlSerializerObject));

 // 序列化
varms = new MemoryStream();

serializer.Serialize(ms,xmlSerializerObject);

ms.Position = 0 ;
varsr = new StreamReader(ms);
varstr = sr.ReadToEnd();
txtXmlSerializer.Text = str;


 // 反序列化
varbuffer = System.Text.Encoding.UTF8.GetBytes(str);
varms2 = new MemoryStream(buffer);
varxmlSerializerObject2 = serializer.Deserialize(ms2) as API.XmlSerializerObject;
lblXmlSerializer.Text = xmlSerializerObject2.Name;
}

/// <summary>
/// 演示SoapFormatter的序列化和反序列化
 /// </summary>
void ShowSoapFormatter()
 {
varsoapFormatterOjbect = new API.SoapFormatterOjbect {ID = Guid.NewGuid(),Name = " ShowSoapFormatter " ,Time = DateTime.Now} ;

varformatter = new System.Runtime.Serialization.Formatters.Soap.SoapFormatter();

 // 序列化
varms = new MemoryStream();

formatter.Serialize(ms,soapFormatterOjbect);

ms.Position = 0 ;
varstr = System.Text.Encoding.UTF8.GetString(ms.GetBuffer());
txtSoapFormatter.Text = str;


 // 反序列化
varbuffer = System.Text.Encoding.UTF8.GetBytes(str);
varms2 = new MemoryStream(buffer);
varsoapFormatterOjbect2 = formatter.Deserialize(ms2) as API.SoapFormatterOjbect;
lblSoapFormatter.Text = soapFormatterOjbect2.Name;
}

/// <summary>
/// 演示BinaryFormatter的序列化和反序列化
 /// </summary>
void ShowBinaryFormatter()
 {
varbinaryFormatterObject = new API.BinaryFormatterObject {ID = Guid.NewGuid(),Name = " BinaryFormatter " ,Time = DateTime.Now} ;

varformatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();

 // 序列化
varms = new MemoryStream();

formatter.Serialize(ms,binaryFormatterObject);

ms.Position = 0 ;
varbuffer = ms.GetBuffer();
varstr = System.Text.Encoding.UTF8.GetString(buffer);
txtBinaryFormatter.Text = str;


 // 反序列化
varms2 = new MemoryStream(buffer);
varbinaryFormatterObject2 = formatter.Deserialize(ms2) as API.BinaryFormatterObject;
lblBinaryFormatter.Text = binaryFormatterObject2.Name;
}

/// <summary>
/// 演示DataContractJsonSerializer的序列化和反序列化
 /// </summary>
void ShowDataContractJsonSerializer()
 {
vardataContractJsonSerializerObject = new API.DataContractJsonSerializerObject {ID = Guid.NewGuid(),Name = " DataContractJsonSerializer " ,Time = DateTime.Now} ;

varserializer = new System.Runtime.Serialization.Json.DataContractJsonSerializer( typeof (API.DataContractJsonSerializerObject));

 // 序列化
varms = new MemoryStream();

serializer.WriteObject(ms,dataContractJsonSerializerObject);

ms.Position = 0 ;
varsr = new StreamReader(ms);
varstr = sr.ReadToEnd();
txtDataContractJsonSerializer.Text = str;


 // 反序列化
varbuffer = System.Text.Encoding.UTF8.GetBytes(str);
varms2 = new MemoryStream(buffer);
vardataContractJsonSerializerObject2 = serializer.ReadObject(ms2) as API.DataContractJsonSerializerObject;
lblDataContractJsonSerializer.Text = dataContractJsonSerializerObject2.Name;
}
}


运行结果：

DataContractSerializer

XmlSerializer

ShowSoapFormatter

BinaryFormatter

DataContractJsonSerializer
