序列化与反序列化之间的转换-创新互联

这里介绍了几种方式之间的序列化与反序列化之间的转换

首先介绍的如何序列化，将object对象序列化常见的两种方式即string和xml对象;

第一种将object转换为string对象，这种比较简单没有什么可谈的；

 public string ScriptSerialize(T t)
        {
            JavaScriptSerializer serializer= new JavaScriptSerializer();
return serializer.Serialize(t);
        }

第二种将object转换为xml对象：

 public string ScriptSerializeToXML(T t)
        {
            XmlSerializer serializer= new XmlSerializer(typeof(T));
            MemoryStream mem= new MemoryStream();
            XmlTextWriter writer= new XmlTextWriter(mem,Encoding.UTF8);
            XmlSerializerNamespaces ns= new XmlSerializerNamespaces();
            ns.Add("","");
            serializer.Serialize(writer,t,ns);
            writer.Close();
return Encoding.UTF8.GetString(mem.ToArray());
        }

下面我主要讲string对象反序列化为对应的对象；

一、将string对象反序列化为object对象

 public T ScriptDeserialize(string strJson)
        {
            JavaScriptSerializer serializer= new JavaScriptSerializer();
return serializer.Deserialize(strJson);
        }

二、将string对象反序列化为list对象

 public List JSONStringToList(string strJson)
        {
            JavaScriptSerializer serializer= new JavaScriptSerializer();
            List objList = serializer.Deserialize>(strJson);
return objList;
        }

三、将string对象反序列化为datatable对象

public DataTable JSONStringToDataTable(string strJson)
        {
            DataTable dt= new DataTable();
if (strJson.IndexOf("[") > -1)//如果大于则strJson存放了多个model对象            {
                strJson= strJson.Remove(strJson.Length - 1, 1).Remove(0, 1).Replace("},{", "};{");
            }
            JavaScriptSerializer serializer= new JavaScriptSerializer();
string[] items = strJson.Split(';');

foreach (PropertyInfo property in typeof(T).GetProperties())//通过反射获得T类型的所有属性            {
                DataColumn col= new DataColumn(property.Name,property.PropertyType);
                dt.Columns.Add(col);
            }
//循环 一个一个的反序列化 for (int i = 0; i < items.Length; i++)
            {
                DataRow dr= dt.NewRow();
//反序列化为一个T类型对象                T temp = serializer.Deserialize(items[i]);
foreach (PropertyInfo property in typeof(T).GetProperties())
                {
                    dr[property.Name]= property.GetValue(temp,null);
                }
                dt.Rows.Add(dr);
            }
return dt;
        }

四、将xml对象反序列化为object对象

 public T JSONXMLToObject(string strJson)
        {
            XmlDocument xdoc= new XmlDocument();
try
            {
                xdoc.LoadXml(strJson);
                XmlNodeReader reader= new XmlNodeReader(xdoc.DocumentElement);
                XmlSerializer ser= new XmlSerializer(typeof(T));
object obj = ser.Deserialize(reader);
return (T)obj;
            }
catch
            {
return default(T);
            }
        }

现在用具体的实例来如何调用他们呢?特别要注意的是将xml对象反序列化objcet对象

 public class LoginObject
    {
public string Account { get; set;}
public string Password { get; set;}
     }

 1  LoginObject loginObject = new LoginObject { Account = account, Password = password };
 2             ExTools.Manage.Class.CScriptSerialize Serialize = new Class.CScriptSerialize();
 3  //将object对象转换为string 4   string strJson=Serialize.ScriptSerialize(loginObject);
 5           
 6  //将object对象转换为xml对象 7  string strJson = Serialize.ScriptSerializeToXML(loginObject);
 8            
 9 
10  //转换为list对象11              List list = Serialize.JSONStringToList(strJson);
12  //将一个xml对象转换为object对象13            strJson = strJson.Substring(1, strJson.Length - 1);
14             loginObject = Serialize.JSONXMLToObject(strJson);
15  //将字符串转换为dataTable16             DataTable dt = Serialize.JSONStringToDataTable(strJson);
17  //将字符串转换为object对象18             loginObject = Serialize.ScriptDeserialize(strJson);
