对象序列化 与反序列化

1.序列化为二进制流

View Code?

using System;

using System.Collections.Generic;

using System.Text;

using System.Runtime.Serialization.Formatters.Binary;

using System.IO;

namespace Common.Serialization.Byte {

    public class ByteSerializer {

        /// <summary>

        /// 对象转换为二进制流

        /// </summary>

        /// <param name="obj">要序列化的对象</param>

        /// <returns>对象序列化后的二进制流</returns>

        public static byte[] Serialize(object obj) {

            if (obj == null) {return null;}

            MemoryStream ms = new MemoryStream();

            try {

                BinaryFormatter formatter = new BinaryFormatter();

                formatter.Serialize(ms, obj);

                return ms.ToArray();

            } finally {

                ms.Close();

            }

        }

        /// <summary>

        /// 二进制流转换为对象

        /// </summary>

        /// <param name="buffer">二进制流缓存</param>

        /// <returns>反序列化后的对象</returns>

        public static object Deserialize(byte[] buffer) {

            if ((buffer == null) || (buffer.Length == 0)) {

                return null;

            }

            MemoryStream ms = new MemoryStream(buffer);

            try {

                BinaryFormatter formatter = new BinaryFormatter();

                return formatter.Deserialize(ms);

            } finally {

                ms.Close();

            }

        }

    }

}

2.序列化为XML

using System;

using System.Text;

using System.IO;

namespace Common.Serialization.Xml {

    public class XmlSerialization {

        /// <summary>

        /// 对象转换为XML字符串

        /// </summary>

        /// <param name="obj">要序列化的对象</param>

        /// <returns>对象序列化后的XML字符串</returns>

        public static string Serialize(object obj) {

            if (obj == null) {

                return null;

            }

            MemoryStream ms = new MemoryStream();

            try {

                System.Xml.Serialization.XmlSerializer formatter = new System.Xml.Serialization.XmlSerializer(obj.GetType());

                formatter.Serialize(ms, obj);

                return Encoding.Default.GetString(ms.ToArray());

            } finally {

                ms.Close();

            }

        }

        /// <summary>

        /// XML字符串转换为对象

        /// </summary>

        /// <param name="xml">XML字符串</param>

        /// <param name="targetType">要反序列化为的对象类型</param>

        /// <returns>反序列化后的对象</returns>

        public static object Deserialize(string xml, Type targetType) {

            if ((xml == null) || (xml.Length == 0)) {

                return null;

            }

            MemoryStream ms = new MemoryStream(Encoding.Default.GetBytes(xml));

            try {

                System.Xml.Serialization.XmlSerializer formatter = new System.Xml.Serialization.XmlSerializer(targetType);

                return formatter.Deserialize(ms);

            } finally {

                ms.Close();

            }

        }

    }

}

3.序列化为JSON

using System;

using System.Text;

using System.IO;

using System.Runtime.Serialization.Json;

namespace Common.Serialization.Json {

    public class JsonSerializer {

        /// <summary>

        /// 对象转换为JSON字符串

        /// </summary>

        /// <param name="obj">要序列化的对象</param>

        /// <returns>对象序列化后的JSON字符串</returns>

        public static string Serialize(object obj) {

            if (obj == null) {return null;}

            MemoryStream ms = new MemoryStream();

            try {

                DataContractJsonSerializer formatter = new DataContractJsonSerializer(obj.GetType());

                formatter.WriteObject(ms, obj);

                return Encoding.UTF8.GetString(ms.ToArray());

            } finally {

                ms.Close();

            }

        }

        /// <summary>

        /// JSON字符串转换为对象

        /// </summary>

        /// <param name="json">JSON字符串</param>

        /// <param name="targetType">要反序列化为的对象类型</param>

        /// <returns>反序列化后的对象</returns>

        public static object Deserialize(string json, Type targetType) {

            if ((json == null) || (json.Length == 0)) {return null;}

            MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(json));

            try {

                DataContractJsonSerializer formatter = new DataContractJsonSerializer(targetType);

                return formatter.ReadObject(ms);

            } finally {

                ms.Close();

            }

        }

    }

}
