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);
