序列化之对象,字符串,byte数组,XML之间的转换（一）

工作一年多了，越来越感到自己不能这样一直下去，在最好的青春里面却已经死了。被时间消磨了意志，被工作杀死了精神。我想，我只要活着，我就要去不断的要求自己，不断的去追求更高的山峰。 放眼四周，有趣的灵魂越来越少。独立的人格也越来越稀薄。我们真的不能为了工作而去工作，那样我们活着就和死了一样。生活充满了重复性，我们不断的重复着自己所做一切，上班下班，周末休息。那样活着其实已经死了。我在这一年里面厌恶这种生活。我决定开始新的生活，制定一个计划，每天朝这个方向努力，哪怕用一年两年甚至半辈子，我也是无怨无悔。 using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Runtime.Serialization; using System.Runtime.Serialization.Formatters.Binary; using System.Text; using System.Threading.Tasks; using Newtonsoft.Json; using System.Xml.Serialization; namespace Test_Control { class Program { static void Main(string[] args) { Object student = new Student() { StudentID = "99", StudentName = "zhang" }; string result = ObjectToString(student); Console.WriteLine(result + "\r\n"); Student newResult = StringToObject(result); Console.WriteLine("ID:{0}, Name:{1}" + "\r\n", newResult.StudentID, newResult.StudentName); //使用UTF8编码将字符串转成byte数组 var byt = SerializeHelper.ConvertToByte("12zhang3"); // Console.WriteLine(BitConverter.ToString(byt)); //使用UTF8编码将byte数组转成字符串 string str = SerializeHelper.ConvertToString(byt); Console.WriteLine(str); //使用指定字符编码将byte数组转成字符串 string strr = SerializeHelper.ConvertToString(byt, Encoding.Unicode); Console.WriteLine(strr); //将对象序列化为二进制数据 var obj = new Student() { StudentID = "9", StudentName = "zhang" }; var arr = SerializeHelper.SerializeToBinary(obj); Console.WriteLine(BitConverter.ToString(arr)); //将对象序列化为XML数据 并且打印 var xml = SerializeHelper.SerializeToXml(obj); Console.WriteLine(BitConverter.ToString(xml)); //将二进制数据反序列化 并且打印 var Bt = new byte[] { 12, 12, 24 }; Student obje = SerializeHelper.DeserializeWithBinary(arr); Console.WriteLine(obje.StudentName); Console.ReadKey(); } /// /// 对象转字符串（序列化后转Base64编码字符串） /// /// 对象 /// 字符串 public static string ObjectToString(T obj) { using (MemoryStream stream = new MemoryStream()) { IFormatter formatter = new BinaryFormatter(); formatter.Serialize(stream, obj); stream.Position = 0; byte[] buffer = new byte[stream.Length]; stream.Read(buffer, 0, buffer.Length); return Convert.ToBase64String(buffer); } } /// /// 字符串转对象（Base64编码字符串反序列化为对象） /// /// 字符串 /// 对象 public static T StringToObject(string str) { using (MemoryStream stream = new MemoryStream()) { byte[] bytes = Convert.FromBase64String(str); stream.Write(bytes, 0, bytes.Length); stream.Position = 0; IFormatter formatter = new BinaryFormatter(); return (T)formatter.Deserialize(stream); } } } /// /// 可序列化的类,用Serializable标示此类可序列化 /// [Serializable] public class Student { public string StudentID { get; set; } public string StudentName { get; set; } } public static class SerializeHelper { /// /// 使用UTF8编码将byte数组转成字符串 /// /// /// public static string ConvertToString(byte[] data) { return Encoding.UTF8.GetString(data, 0, data.Length); } /// /// 使用指定字符编码将byte数组转成字符串 /// /// /// /// public static string ConvertToString(byte[] data, Encoding encoding) { return encoding.GetString(data, 0, data.Length); } /// /// 使用UTF8编码将字符串转成byte数组 /// /// /// public static byte[] ConvertToByte(string str) { return Encoding.UTF8.GetBytes(str); } /// /// 使用指定字符编码将字符串转成byte数组 /// /// /// /// public static byte[] ConvertToByte(string str, Encoding encoding) { return encoding.GetBytes(str); } /// /// 将对象序列化为二进制数据 /// /// /// public static byte[] SerializeToBinary(object obj) { MemoryStream stream = new MemoryStream(); BinaryFormatter bf = new BinaryFormatter(); bf.Serialize(stream, obj); byte[] data = stream.ToArray(); stream.Close(); return data; } /// /// 将对象序列化为XML数据 /// /// /// public static byte[] SerializeToXml(object obj) { MemoryStream stream = new MemoryStream(); XmlSerializer xs = new XmlSerializer(obj.GetType()); xs.Serialize(stream, obj); byte[] data = stream.ToArray(); stream.Close(); return data; } /// /// 将二进制数据反序列化 /// /// /// public static object DeserializeWithBinary(byte[] data) { //注意，在反序列化的时候，将byte[]写入流以后，需要将游标移到首位，即将Position置零，否则反序列化将报错。 MemoryStream stream = new MemoryStream(); stream.Write(data, 0, data.Length); stream.Position = 0; BinaryFormatter bf = new BinaryFormatter(); object obj = bf.Deserialize(stream); stream.Close(); return obj; } /// /// 将二进制数据反序列化为指定类型对象 /// /// /// /// public static T DeserializeWithBinary(byte[] data) { return (T)DeserializeWithBinary(data); } /// /// 将XML数据反序列化为指定类型对象 /// /// /// /// public static T DeserializeWithXml(byte[] data) { MemoryStream stream = new MemoryStream(); stream.Write(data, 0, data.Length); stream.Position = 0; XmlSerializer xs = new XmlSerializer(typeof(T)); object obj = xs.Deserialize(stream); stream.Close(); return (T)obj; } } }
