C#_Winform_聊天机器人

最近研究微信公众平台，搭建了一个微信聊天机器人，调用小黄鸡的公众接口，实现在线和小黄鸡聊天的功能。

接口调用不是很麻烦，不过是php版本，所以研究了一下C#的功能模块，

Winfrom版

       {
            if (e.KeyValue == 13)

            //设定光标所在位置 
            this.richTextBox1.SelectionStart = richTextBox1.TextLength-1;
            //滚动到当前光标处 
            this.richTextBox1.ScrollToCaret();
        } 

    }
}

应用的类代码：应用接口用小黄鸡那边传回来的是一个json形式的内容，所以应用到json的解析问题，我应用的是网上通用的方法Newtonsoft.Json，可以从网上下载对应的DLL
