asp.net JavaScriptSerializer實現序列化和反序列化

通過JavaScriptSerializer來實現。它的名字空間為：System.Web.Script.Serialization

如果要使用它，還須新增

System.Web.Extensions庫檔案引用

參考實體類：Customer

 

public class Customer
{
    public int Unid { get; set; }
    public string CustomerName { get; set; }
}

 

 

類JavaScriptSerializer描述：為啟用 AFAX 的應用程式提供序列化和反序列化功能。

（一） 序列化

方法：public string Serialize(Object obj)，用於將物件轉換為 JSON 字串

public string ScriptSerialize(Customer customer)
{
     JavaScriptSerializer js = new JavaScriptSerializer();

    return js.Serialize(customer);
}

 

測試

Customer cc = new Customer { Unid = 1, CustomerName = "John" };
string strJson = ScriptSerialize(cc);

Console.WriteLine(strJson);

 

（二）反序列化

public Customer ScriptDeserialize(string strJson)
{
     JavaScriptSerializer js = new JavaScriptSerializer();
    return js.Deserialize<Customer>(strJson);

}

 

通過Deserialize<T>方法來實現。

測試：

 

Customer c1 = ScriptDeserialize(strJson);
Console.WriteLine(c1.Unid + " " + c1.CustomerName);

 

 

（三）方法泛型

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

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

 

測試：

Customer cc = new Customer { Unid = 1, CustomerName = "John" };
string strJson = ScriptSerialize<Customer>(cc);
Console.WriteLine(strJson); 

Customer c1 = ScriptDeserialize<Customer>(strJson);
Console.WriteLine(c1.Unid + " " + c1.CustomerName);
