化零为整WCF(9) - 序列化(DataContractSerializer, XmlSerializer, DataContractJsonSerializer, SoapFormatter, BinaryFormatter)

作者：webabcd


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 Guid ID { get; set; }

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

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

                [DataMember(Order = 3)]
                public DateTime Time { 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 Guid ID { get; set; }

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

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

                [XmlElement(Order = 3)]
                public DateTime Time { 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 Guid ID { get; set; }
                public string Name { get; set; }
                public int Age { get; set; }
                public DateTime Time { 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 Guid ID { get; set; }
                public string Name { get; set; }
                public int Age { get; set; }
                public DateTime Time { 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 Guid ID { get; set; }

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

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

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