豆瓣API查询和显示图书的信息

第一步：GetDataSource.cs类，用来通过HTTP协议从网络获取json文件，并通过文件流操作将json转化为string类型返回

第二步：通过c#语言在visual studio上画图形界面

第三步：引用”using Newtonsoft.Json.Linq;”，使用JObject来解析返回的string类型的json文件，获取符合关键字”q”的所有图书
遍历文件获取图书信息，将内容添加带List集合上，并绑定到datagridview.显示在窗体上；

第四步：通过传参数（图书的API），获取每本图书的信息，并显示在WinForm窗体上。

第五步：修改程序，使用多线程和委托技术，防止在获取大量数据时候界面卡死情况。

            catch (Exception)
            {
                MessageBox.Show("发生异常，请检查！");
            }
        }

        /// 

        ///     返回按钮，隐藏显示的信息
        /// 
        /// sender
        /// e
        private void btnCan
cle_Click(object sender, EventArgs e)
        {
            panel1.Visible = false;
            dgvBookInfo.Visible = true;
