Asp.net中将对象转化为JSON格式的字符串

[csharp]
/// <summary> 
/// Converts an object to its JSON representation. 
/// </summary> 
/// <param name="obj"></param> 
/// <returns></returns> 
public static string ConvertToJson(object obj) 
{ 
    return new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(obj); 
}
