使用JSON.net 生成实体类的JSON串是很简单的,比如:
//实体类


public class SysNavModel
{
public SysNavModel()
{ }
// / <summary>
// / 构造函数 sys_nav
// / </summary>
// / <param name="navid">navid</param>
// / <param name="title">title</param>
// / <param name="url">url</param>
// / <param name="iconcls">iconcls</param>
// / <param name="parentid">parentid</param>
// / <param name="visible">visible</param>
// / <param name="orderid">orderid</param>
public SysNavModel( int ? navid, string title, string url, string iconcls, int ? parentid, bool ? visible, int ? orderid)
{
this .navid = navid;
this .title = title;
this .url = url;
this .iconcls = iconcls;
this .parentid = parentid;
this .visible = visible;
this .orderid = orderid;
}
#region 实体属性

//主要代码
public override string ToString()
{
StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
new JsonSerializer().Serialize( new JsonTextWriter(sw), this );
return sb.ToString();
}
public override string ToString()
{
StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
new JsonSerializer().Serialize( new JsonTextWriter(sw), this );
return sb.ToString();
}
}
重写了实体类的ToString()方法
在调时 直接调用实体类的ToString() 方法就可以生JSON字符串了。
简单吧
我们可以封装一个方法以便以后使用
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();
}
{
StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
JsonSerializer json = new JsonSerializer();
json.Serialize( new JsonTextWriter(sw),obj);
return sb.ToString();
}
