使用JSON.net 生成实体类的JSON串是很简单的，比如：
//实体类
代码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
private int? _navid;
private string _title;
private string _url;
private string _iconcls;
private int? _parentid;
private bool? _visible;
private int? _orderid;
private string _ptag;
/// <summary>
/// navid
/// </summary>
public int? navid
{
set { _navid = value; }
get { return _navid; }
}
/// <summary>
/// 页面标记
/// </summary>
public string ptag
{
get { return _ptag; }
set { _ptag = value; }
}
/// <summary>
/// 导航菜单名称
/// </summary>
public string title
{
set { _title = value; }
get { return _title; }
}
/// <summary>
/// 链接地址
/// </summary>
public string url
{
set { _url = value; }
get { return _url; }
}
/// <summary>
/// ICON 样式类名
/// </summary>
public string iconcls
{
set { _iconcls = value; }
get { return _iconcls; }
}
/// <summary>
/// 上级ID
/// </summary>
public int? parentid
{
set { _parentid = value; }
get { return _parentid; }
}
/// <summary>
/// 是否显示
/// </summary>
public bool? visible
{
set { _visible = value; }
get { return _visible; }
}
/// <summary>
/// 排序ID
/// </summary>
public int? orderid
{
set { _orderid = value; }
get { return _orderid; }
}
/// <summary>
/// 权限数组
/// </summary>
public ArrayList Permissions
{
get
{
return NavPermissionDal.Current.GetPermissionArray(this.navid.Value);
}
}

//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();
}}
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();
}
