问题描述
我已经用Json创建了一个项目...来自Web服务的所有内容都转换为json，但是当我从菜单中选择某些项目时，响应时间很慢.
有人知道如何减少时间吗?
问候.
Default.aspx页的代码:
Hi I had create a project with Json ... Everything that cames from webservice is converted to json but the time of response is very slow when i select some item from the menu.

推荐答案
JSON数据最好在Javascript中使用，而不是在C#代码中使用.根据您的代码，您正在执行非常大的字符串处理操作，这不可避免地会降低性能.尝试在javascript中使用JSON字符串，看看有什么区别.
JSON data is best used in Javascript, not in C# code. As per your code you are doing a really big string crunching operation, and that''s unavoidably reducing the performance. Try to use the JSON string in javascript and see the difference.
