实体类转json 泛型集合list转json

用json.net的方式。参考网址：http://www.cnblogs.com/hxling/archive/2010/10/31/1865575.html

主要的代码：

public static string ToJson(object obj)

{

   StringBuilder sb = new StringBuilder();

   StringWriter sw = new StringWriter(sb);



   JsonSerializer json = new JsonSerializer();

   json.Serialize(new JsonTextWriter(sw),obj);



   return sb.ToString();

 }

泛型集合List转json

 string result = string.Empty;

 List<ApplicationDomainCategory> list= new ApplicationDomainCategoryManager().GetAll();

 result=JsonConvert.SerializeObject(list);

 return result;

 

微软自带的方式：

引用命名空间 using System.Web.Script.Serialization;

JavaScriptSerializer jss = new JavaScriptSerializer();

result = jss.Serialize(data);//data为实体类
