我试图在使用c#和JSON的网站上加载JSON文件。净
然而，当它运行时，我遇到了一个问题，因为所有的JSON都在[]内。
JSON:
[{"embed_count":"16","name":"live_user_catreina","stream_count":"133","category":"gaming","format":"live","channel_count":272,"title":"SWTOR - Sith Marauder - L42 - Belsavis - The Fatman","featured":true,"site_count":"117","abuse_reported":false,"channel":{"image_url_large":"http://static-cdn.jtvnw.net/jtv_user_pictures/catreina-profile_image-2c63d1c5b60987da-300x300.jpeg","channel_url":"http://www.justin.tv/catreina","category_title":"Gaming","screen_cap_url_large":"http://static-cdn.jtvnw.net/previews/live_user_catreina-320x240.jpg","mature":null,"subcategory":null,"category":"gaming","image_url_medium":"http://static-cdn.jtvnw.net/jtv_user_pictures/catreina-profile_image-2c63d1c5b60987da-150x150.jpeg","subcategory_title":null,"status":"SWTOR - Sith Marauder - L42 - Belsavis - The Fatman","screen_cap_url_medium":"http://static-cdn.jtvnw.net/previews/live_user_catreina-150x113.jpg","image_url_small":"http://static-cdn.jtvnw.net/jtv_user_pictures/catreina-profile_image-2c63d1c5b60987da-70x70.jpeg","timezone":"US/Eastern","screen_cap_url_small":"http://static-cdn.jtvnw.net/previews/live_user_catreina-70x53.jpg","id":5895485,"views_count":"6142420","embed_enabled":true,"embed_code":" <object type="application/x-shockwave-flash" height="295" width="353" id="live_embed_player_flash" data="http://www.justin.tv/widgets/live_embed_player.swf?channel=catreina" bgcolor="#000000"><param name="allowFullScreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="movie" value="http://www.justin.tv/widgets/live_embed_player.swf" /><param name="flashvars" value="start_volume=25&channel=catreina&auto_play=false" /></object>n","producer":true,"image_url_tiny":"http://static-cdn.jtvnw.net/jtv_user_pictures/catreina-profile_image-2c63d1c5b60987da-50x50.jpeg","image_url_huge":"http://static-cdn.jtvnw.net/jtv_user_pictures/catreina-profile_image-2c63d1c5b60987da-600x600.jpeg","language":"en","tags":"games gaming lord lotro mmo mmorpg of online pc rings rpg sc2 scii starcraft starcraft2 the vindictus warcraft wow","login":"catreina","screen_cap_url_huge":"http://static-cdn.jtvnw.net/previews/live_user_catreina-630x473.jpg","title":"Gaming With Catreina"},"video_height":720,"language":"en","video_bitrate":1987.1328125,"id":"2309110144","meta_game":"Star Wars: The Old Republic","broadcaster":"fme","broadcast_part":4,"audio_codec":"uncompressed","up_time":"Mon Dec 26 00:06:03 2011","video_width":1280,"geo":"US","channel_view_count":6133751,"channel_subscription":false,"embed_enabled":true,"stream_type":"live","video_codec":"AVC"}]
我试着用下面的代码加载它:
class Program
{
static void Main(string[] args)
{
WebClient webclient = new WebClient();
var data = webclient.DownloadString("http://api.justin.tv/api/stream/list.json?channel=catreina");
JObject jo = JObject.Parse(data);
Console.WriteLine("Embed Count: " + jo["embed_count"]);
Console.ReadLine();
}
}
但是它显然给了我这个错误
Unhandled Exception: System。异常:从JsonReader读取jobobject时出错。当前JsonReader项不是对象:StartArray
我如何加载JSON与[]，然后解析值?
当[]在JSON中使用时，这意味着数组。
用JArray代替JObject。
WebClient webclient = new WebClient();
var data = webclient.DownloadString("http://api.justin.tv/api/stream/list.json?channel=catreina");
JArray ja = JArray.Parse(data);
Console.WriteLine("Embed Count: " + ja[0]["embed_count"]);
Console.ReadLine();
