[C #] Using the console to get the weather forecast

This example uses the JSON API provided by the Central Meteorological Administration Website (http://www.nmc.gov.cn) to implement the following ideas:

1, access to the province (including municipalities, autonomous regions, etc., hereinafter referred to as the province) of the website (http://www.nmc.gov.cn/f/rest/province), return the corresponding province name (name), code, etc., as shown in:

2, according to the code returned above, the code is stitched at the back of the URL (http://www.nmc.gov.cn/f/rest/province), such as the Returned code is AGD (Guangdong province), the post-splicing URL is http// Www.nmc.gov.cn/f/rest/province/AGD to obtain the corresponding city name, code, as shown in:

3, according to the code returned above, the code is spliced at the back of the URL (http://www.nmc.gov.cn/f/rest/real/), such as the return code is 59287 (Guangzhou), the post-splicing URL is http://www.nmc.gov.cn/f/ rest/real/59287 to obtain the corresponding weather information as shown in:

4, this example uses the technology for the HttpWebRequest class, the HttpWebResponse class and the Newtonsoft.Json.JsonConvert class the use, oneself has not understood, please carry on the Baidu by oneself;
