C#序列化字符串，对象，xml，json,集合数组，字典
public class Person { public Person() { } public Person(string name, int age) { Name = name; Age = age; } public string Name { get; set; } public int Age { get; set; } public DateTime LastLoginTime { get; set; } public List<Course> Courses = new List<Course>(); }
public class Course { public Course() { } public Course(string name, string description) { Name = name; Description = description; } public string Name { get; set; } public string Description { get; set; } }??对象和xml序列化和反序列化方法
/// <summary> /// 序列化 /// </summary> /// <param name="filePath"></param> public static void Serialiaze(String filePath) { Person c = new Person("James Chen",35); c.Courses.Add(new Course("高等数学", "思维工具")); c.Courses.Add(new Course("大学英语", "交流工具")); c.Courses.Add(new Course("离散数学", "计算机理论")); XmlSerializer xs = new XmlSerializer(typeof(Person)); Stream stream = new FileStream(filePath, FileMode.Create, FileAccess.Write, FileShare.ReadWrite); xs.Serialize(stream, c); stream.Close(); } /// <summary> /// 反序列化 /// </summary> /// <param name="filePath"></param> public static void Deserialize(String filePath) { XmlSerializer xs = new XmlSerializer(typeof(Person)); Stream stream = new FileStream(filePath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite); Person p = (Person)xs.Deserialize(stream); stream.Close(); }?调用方法
string path = Server.MapPath("upload/test.xml");Serializer.Serialiaze(path);Serializer.Deserialize(path);?
2.字符串和对象的序列化和反序列化
/// <summary> /// 序列化 对象到字符串 /// </summary> /// <param name="obj">泛型对象</param> /// <returns>序列化后的字符串</returns> public static string Serialize<T>(T obj) { try { IFormatter formatter = new BinaryFormatter(); MemoryStream stream = new MemoryStream(); formatter.Serialize(stream, obj); stream.Position = 0; byte[] buffer = new byte[stream.Length]; stream.Read(buffer, 0, buffer.Length); stream.Flush(); stream.Close(); return Convert.ToBase64String(buffer); } catch (Exception ex) { throw new Exception("序列化失败,原因:" + ex.Message); } } /// <summary> /// 反序列化 字符串到对象 /// </summary> /// <param name="obj">泛型对象</param> /// <param name="str">要转换为对象的字符串</param> /// <returns>反序列化出来的对象</returns> public static T Desrialize<T>(T obj, string str) { try { obj = default(T); IFormatter formatter = new BinaryFormatter(); byte[] buffer = Convert.FromBase64String(str); MemoryStream stream = new MemoryStream(buffer); obj = (T)formatter.Deserialize(stream); stream.Flush(); stream.Close(); } catch (Exception ex) { throw new Exception("反序列化失败,原因:" + ex.Message); } return obj; }?调用方法
//序列化 DataTable dt = new DataTable(); dt.Columns.Add("ID"); dt.Columns.Add("Name"); dt.Rows.Add(new object[] { 1, "first" }); dt.Rows.Add(new object[] { 2, "second" }); string result = SerializeUtilities.Serialize(dt); Response.Write(result); //反序列化 string mystr = result; DataTable _resDT = new DataTable(); _resDT = (DataTable)SerializeUtilities.Desrialize(_resDT, mystr); Response.Write("<br>反序列化结果<br>" + _resDT.Rows[0][0].ToString() + ":" + _resDT.Rows[0][1].ToString() + "<br>"); Response.Write(_resDT.Rows[1][0].ToString() + ":" + _resDT.Rows[1][1].ToString() + "<br>");?
3.JSON序列化和反序列化的处理
/// <summary> /// JSON序列化 /// </summary> public static string JsonSerializer<T>(T t) { DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T)); MemoryStream ms = new MemoryStream(); ser.WriteObject(ms, t); string jsonString = Encoding.UTF8.GetString(ms.ToArray()); ms.Close(); return jsonString; } /// <summary> /// JSON反序列化 /// </summary> public static T JsonDeserialize<T>(string jsonString) { DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T)); MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString)); T obj = (T)ser.ReadObject(ms); return obj; } /// <summary> /// JSON序列化 /// </summary> public static string JsonSerializerM<T>(T t) { DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T)); MemoryStream ms = new MemoryStream(); ser.WriteObject(ms, t); string jsonString = Encoding.UTF8.GetString(ms.ToArray()); ms.Close(); //替换Json的Date字符串 string p = @"\\/Date\((\d+)\+\d+\)\\/"; MatchEvaluator matchEvaluator = new MatchEvaluator(ConvertJsonDateToDateString); Regex reg = new Regex(p); jsonString = reg.Replace(jsonString, matchEvaluator); return jsonString; } /// <summary> /// JSON反序列化 /// </summary> public static T JsonDeserializeM<T>(string jsonString) { //将"yyyy-MM-dd HH:mm:ss"格式的字符串转为"\/Date(1294499956278+0800)\/"格式 string p = @"\d{4}-\d{2}-\d{2}\s\d{2}:\d{2}:\d{2}"; MatchEvaluator matchEvaluator = new MatchEvaluator(ConvertDateStringToJsonDate); Regex reg = new Regex(p); jsonString = reg.Replace(jsonString, matchEvaluator); DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T)); MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString)); T obj = (T)ser.ReadObject(ms); return obj; } /// <summary> /// 将Json序列化的时间由/Date(1294499956278+0800)转为字符串 /// </summary> private static string ConvertJsonDateToDateString(Match m) { string result = string.Empty; DateTime dt = new DateTime(1970, 1, 1); return result; } /// <summary> /// 将时间字符串转为Json时间 /// </summary> private static string ConvertDateStringToJsonDate(Match m) { string result = string.Empty; DateTime dt = DateTime.Parse(m.Groups[0].Value); dt = dt.ToUniversalTime(); TimeSpan ts = dt - DateTime.Parse("1970-01-01"); result = string.Format("\\/Date({0}+0800)\\/", ts.TotalMilliseconds); return result; }?调用代码
Person p = new Person(); p.Name = "张三"; p.LastLoginTime = DateTime.Now; p.Age = 28; string jsonString = JsonSerializeHelper.JsonSerializer<Person>(p); Response.Write(jsonString); Person pe = JsonSerializeHelper.JsonDeserialize<Person>(jsonString); ///JSON序列化和反序列化日期时间的处理 Person p2 = new Person(); p2.Name = "张三"; p2.Age = 28; p2.LastLoginTime = DateTime.Now; string jsonString2 = JsonSerializeHelper.JsonSerializerM<Person>(p); Person pe2 = JsonSerializeHelper.JsonDeserializeM<Person>(jsonString); ///JSON序列化和反序列化集合、字典、数组的处理 List<Person> list = new List<Person>() { new Person(){ Name="张三", Age=28,LastLoginTime = DateTime.Now}, new Person(){ Name="李四", Age=25,LastLoginTime = DateTime.Now} }; string jsonString3 = JsonSerializeHelper.JsonSerializer<List<Person>>(list); Dictionary<string, string> dic = new Dictionary<string, string>(); dic.Add("Name", "张三"); dic.Add("Age", "28"); string jsonString4 = JsonSerializeHelper.JsonSerializer<Dictionary<string, string>>(dic);?
