一、 让文本变成声音
.Net里面自带了一个语音类库:System.Speech,调用系统的语音功能,就能实现string到语音的转换,很简单(记得先把电脑音量调大一下):
//Add System.Speech reference first
using System.Speech.Synthesis;
var reader =
new SpeechSynthesizer();
reader.SpeakAsync(
"I'm a programer. Hello, world! ");
Hello, world! 你听到了……这里我用了SpeakAsync方法,也就是异步执行,不会阻塞主线程。你也可以直接调用Speak()方法,也就是在一个线程里面——突然想到可以利用Speak()方法来调试程序,把断点或者Log换成Speak(): 当别人辛苦的翻阅数百行的日志--而你的电脑用悠扬的语音告诉你:“This user's entity is null, here is a bug!”,高端大气上档次呀!
二、 获取本地实时天气
园子里面有很多获取天气的API文章,这里就不介绍了,给一个CSDN链接,还算比较全:天气预报API接口大全
我这里用的都是新浪的API,最简单快捷。获取本地的实时天气,分为两步:一、根据电脑公网IP 获取当前城市;二、根据城市获取天气信息。
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"]);
获取到的地理信息是json格式,反序列成dynamic动态类型,不需要再去创建个类去和json数据对应,C#获取json数据就和javascript中的操作差不多了,用了当然这样也就肯定没有VS的智能感知。取到的省市信息都是UTF-8编码的,所以要取出来的话,进行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);
这次取到的天气信息就是XML格式的了,也很方便。但需要注意的是此,构建URL的时候要把城市采用GB2312格式编码,WebClient需要指定UTF-8格式。天气信息取到了,下面就是编字符串,让它说话了,这里附上全部的代码,总共23行:
class="code_img_closed" id="code_img_closed_47186264-37bc-4f6f-a1e1-d8db8333f78f" alt="" />
logs_code_hide('47186264-37bc-4f6f-a1e1-d8db8333f78f',event)" style="display:none">
1 //Initialize Speaker
2 var reader =
new SpeechSynthesizer();
3 reader.Speak(
"I'm a programer,Hello, World! ");
4 5 var webClient =
new WebClient() { Encoding = Encoding.UTF8 };
6 //Get location city
7 var location = webClient.DownloadString(
"http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json");
8 var json =
new JavaScriptSerializer().Deserialize<dynamic>(location);
9 //Read city from utf-8 format
10 var city = HttpUtility.UrlDecode(json[
"city"]);
11 //Get weather data(xml format)
12 string weather = webClient.DownloadString(
string.Format(
13 "http://php.weather.sina.com.cn/xml.php?city={0}&password=DJOYnieT8234jlsK&day=0",
14 HttpUtility.UrlEncode(json[
"city"], Encoding.GetEncoding(
"GB2312"))));
15 //Console.WriteLine(weather);
16 var xml =
new XmlDocument();
17 xml.LoadXml(weather);
18 //Get weather detail
19 var root = xml.SelectSingleNode(
"/Profiles/Weather");
20 var detail = root[
"status1"].InnerText +
"," + root[
"direction1"].InnerText
21 + root[
"power1"].InnerText.Replace(
"-",
"到") +
"级,"22 + root[
"gm_s"].InnerText + root[
"yd_s"].InnerText;
23 reader.SpeakAsync(
"今天是" + DateTime.Now.ToShortDateString() +
"," + city +
" " + detail);
