问题

最近写 socket程序遇到几个问题一直没有解决  记下  日后继续解决

问题背景：两个程序socket通讯 序列化

 /// <summary>
        /// 从对象转化为xml字符串
        /// </summary>
        /// <param name="obj"></param>
        /// <returns></returns>
        public static byte[] SerializeXml(object obj)
        {
            string xml = string.Empty;
            XmlSerializer xs = new XmlSerializer(obj.GetType());
            XmlWriterSettings settings = new XmlWriterSettings()
            {
                Encoding = Encoding.UTF8
            };
            MemoryStream stream = new MemoryStream();//如果用StringBuilder，转化出来的xml 编码是UTF16，XmlWriterSettings不起作用，. 只能对Stream进行编码更改。
            using (XmlWriter writer = XmlWriter.Create(stream, settings))
            {
                xs.Serialize(writer, obj);
            }
            return Encoding.UTF8.GetBytes(Encoding.UTF8.GetString(stream.ToArray(), 0,stream.ToArray().Length).Trim());//此处转化为xml字符串后，会有一个编码是65279的小空格，大约只占1个像素.
        }


        public static byte[] Serialize(object obj)
        {
            DataContractSerializer serializer = new DataContractSerializer(obj.GetType());

            MemoryStream ms = new MemoryStream();

            serializer.WriteObject(ms, obj);

            ms.Seek(0, 0);
            return ms.ToArray();
        }

        public static T Deserialize<T>(byte[] data)
        {
            string _serializeString = Encoding.UTF8.GetString(data, 0, data.Length);
            DataContractSerializer serializer = new DataContractSerializer(typeof(T));

            MemoryStream ms = new MemoryStream(data);
            ms.Seek(0, 0);
            return (T)(serializer.ReadObject(ms));
        }

        public static string SerializeToString(object obj)
        {
            DataContractSerializer serializer = new DataContractSerializer(obj.GetType());

            MemoryStream ms = new MemoryStream();

            serializer.WriteObject(ms, obj);

            return Encoding.UTF8.GetString(ms.ToArray(), 0, (int)ms.Length);
        }

        public static T DeserializeFromString<T>(string data)
        {
            byte[] buffer = Encoding.UTF8.GetBytes(data);

            DataContractSerializer serializer = new DataContractSerializer(typeof(T));

            MemoryStream ms = new MemoryStream(buffer);
            ms.Seek(0, 0);
            return (T)(serializer.ReadObject(ms));
        }

的obejet to byte的时候和byte to obeject的时候再一个程序里面不报错 

可是移至两个工程的时候   调试截取的数据都一样一到最后一步转换的时候就报 ” 根节点错误在第一行第一列“网上搜了很多办法都没解决 

换了很多方法也没完成 

最后没办法无奈了 

只能先转换成json string  然后再在socket中传送 string   类型 

最后在把jsonstring转换成对象  

也算是不完美的完美

代码：

//序列化   注意此方法 需要引入第三方类库  newtonsoft
JsonConvert.SerializeObject( new Class1() { t = "1" })
//反序列化  引入命名空间 如果是net3.5以下 需要下载web扩展dll
//否则直接引入这个空间就ok  using System.Web.Script.Serialization;
JavaScriptSerializer jss = new JavaScriptSerializer();
                Class1 t = jss.Deserialize<Class1>(receivedContent);
                receivedContent = t.t;
