一、 讓文本變成聲音
//
Add System.Speech reference first
using System.Speech.Synthesis;
var reader = new SpeechSynthesizer();
reader.SpeakAsync( " I'm a programer. Hello, world! ");
using System.Speech.Synthesis;
var reader = new SpeechSynthesizer();
reader.SpeakAsync( " I'm a programer. Hello, world! ");
Hello, world! 你聽到了……這里我用了SpeakAsync方法,也就是異步執行,不會阻塞主線程。你也可以直接調用Speak()方法,也就是在一個線程里面——突然想到可以利用Speak()方法來調試程序,把斷點或者Log換成Speak(): 當別人辛苦的翻閱數百行的日志--而你的電腦用悠揚的語音告訴你:“This user's entity is null, here is a bug!”,高端大氣上檔次呀!
二、 獲取本地實時天氣
園子里面有很多獲取天氣的API文章,這里就不介紹了,給一個CSDN鏈接,還算比較全:天氣預報API接口大全
我這里用的都是新浪的API,最簡單快捷。獲取本地的實時天氣,分為兩步:一、根據電腦公網IP 獲取當前城市;二、根據城市獲取天氣信息。
var webClient =
new WebClient() { Encoding = Encoding.UTF8 };
// Get location city
var location = webClient.DownloadString( " http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json ");
var json = new JavaScriptSerializer().Deserialize<dynamic>(location);
// Read city from utf-8 format
var city = HttpUtility.UrlDecode(json[ " city "]);
// Get location city
var location = webClient.DownloadString( " http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json ");
var json = new JavaScriptSerializer().Deserialize<dynamic>(location);
// Read city from utf-8 format
var city = HttpUtility.UrlDecode(json[ " city "]);
獲取到的地理信息是json格式,反序列成dynamic動態類型,不需要再去創建個類去和json數據對應,C#獲取json數據就和javascript中的操作差不多了,用了當然這樣也就肯定沒有VS的智能感知。取到的省市信息都是UTF-8編碼的,所以要取出來的話,進行Decode。
//
Get weather data(xml format)
string weather = webClient.DownloadString( string.Format(
" http://php.weather.sina.com.cn/xml.php?city={0}&password=DJOYnieT8234jlsK&day=0 ",
HttpUtility.UrlEncode(json[ " city "], Encoding.GetEncoding( " GB2312 "))));
// Console.WriteLine(weather);
var xml = new XmlDocument();
xml.LoadXml(weather);
string weather = webClient.DownloadString( string.Format(
" http://php.weather.sina.com.cn/xml.php?city={0}&password=DJOYnieT8234jlsK&day=0 ",
HttpUtility.UrlEncode(json[ " city "], Encoding.GetEncoding( " GB2312 "))));
// Console.WriteLine(weather);
var xml = new XmlDocument();
xml.LoadXml(weather);
這次取到的天氣信息就是XML格式的了,也很方便。但需要注意的是此,構建URL的時候要把城市采用GB2312格式編碼,WebClient需要指定UTF-8格式。天氣信息取到了,下面就是編字符串,讓它說話了,這里附上全部的代碼,總共23行:
