常用代码片段

1.封装为一个方法，将对象序列化为json格式

public static HttpResponseMessage toJson(Object obj)
{
     String str;
     if (obj is String ||obj is Char)
     {
         str = obj.ToString();
     }
     else
     {
         JavaScriptSerializer serializer = new JavaScriptSerializer();
         str = serializer.Serialize(obj);
     }
     HttpResponseMessage result = new HttpResponseMessage { Content = new StringContent(str, Encoding.GetEncoding("UTF-8"), "application/json") };
     return result;
}
