JSON 序列化和反序列化——JavaScriptSerializer实现

通过JavaScriptSerializer来实现。它的名字空间为：System.Web.Script.Serialization

如果要使用它，还须添加

System.Web.Extensions库文件引用 

参考实体类：Customer

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

类JavaScriptSerializer描述：为启用 AFAX 的应用程序提供序列化和反序列化功能。

（一） 序列化

方法：public string Serialize(Object obj)，用于将对象转换为 JSON 字符串

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

    return js.Serialize(customer);
}

测试

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);

}

通过Deserialize<T>方法来实现。

测试：

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);
}

测试：

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);
