.NET调用百度天气api经验

首先申请api 获取AK码

然后获取JSON数据

然后解析JSON数据

最后呈现出读取的数据

个人修改 只呈现天气预报部分

注：其中使用的类库直接使用转载博文中类库

只是修改了其中的program.CS文件中的部分

修改部分如下

    using System.Collections.Generic;
    using System.Text;
    using System.Net;
    using Newtonsoft.Json;
    using System.Xml.Serialization;

                    }
                    //Console.WriteLine("");
    
                    /*

                XmlSerializer xs = new XmlSerializer(typeof(T));
                using (StringReader strReader = new StringReader(xmlContent))
                {
                    XmlReader xmlReader = XmlReader.Create(strReader);
                    return (T)xs.Deserialize(xmlReader);
                }
            }
        }
    }

1 WebClient类的DownloadString方法 使用

即把网页的数据返回以String形式返回

var json=WebClient.DownloadString(url)//返回JSON形式的数据

2 JSON数据的解析

本文学习转载的博文 使用的是

JsonConvert.DeserializeObject<BaiduTQ>(json);方法

要使用这个必须调用Newton.json 类库 以及Newton.json.dll文件

3 JSON格式解析的其他学习
