我正在反序列化JSON

{ ＆＃34; topalbums＆＃34;：{ ＆＃34;专辑＆＃34;：[ { ＆＃34;姓名＆＃34;：＆＃34;贫民窟的百万富翁＆＃34;，＆＃34; playcount＆＃34;：1442872，＆＃34; URL＆＃34;：＆＃34; https://www.last.fm/music/A.R.+Rahman/Slumdog+Millionaire＆＃34 ;, ＆＃34;艺术家＆＃34;：{ ＆＃34;名称＆＃34;：＆＃34; A.R。拉赫曼＆＃34 ;, ＆＃34; MBID＆＃34;：＆＃34; e0bba708-bdd3-478d-84ea-c706413bedab＆＃34 ;, ＆＃34; URL＆＃34;：＆＃34; https://www.last.fm/music/A.R.+Rahman＆＃34; }，＆＃34;图像＆＃34;：[ { ＆＃34;＃文本＆＃34;：＆＃34; https://lastfm-img2.akamaized.net/i/u/34s/14c3f3bc7834415db7765563177e4bf6.png＆＃34 ;, ＆＃34;大小＆＃34;：＆＃34;小＆＃34; }， { ＆＃34;＃文本＆＃34;：＆＃34; https://lastfm-img2.akamaized.net/i/u/64s/14c3f3bc7834415db7765563177e4bf6.png＆＃34 ;, ＆＃34;大小＆＃34;：＆＃34;介质＆＃34; }， { ＆＃34;＃文本＆＃34;：＆＃34; https://lastfm-img2.akamaized.net/i/u/174s/14c3f3bc7834415db7765563177e4bf6.png＆＃34 ;, ＆＃34;大小＆＃34;：＆＃34;大＆＃34; }， { ＆＃34;＃文本＆＃34;：＆＃34; https://lastfm-img2.akamaized.net/i/u/300x300/14c3f3bc7834415db7765563177e4bf6.png＆＃34 ;, ＆＃34;大小＆＃34;：＆＃34;海＆＃34; } ] } ] } }

string artist = txtMusic.Text;
var requestUrl = "http://ws.audioscrobbler.com/2.0/?method=artist.gettopalbums&artist=" + artist + "&api_key=&format=json";

var client = new WebClient();
client.Headers.Add("user-agent", "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome / 58.0.3029.110 Safari / 537.36");

var response = client.DownloadString(requestUrl);

Response.Write(response);
dynamic stuff = JObject.Parse(response);
string name = stuff.album.name;
lblInfo.InnerText = name;

我无法弄清楚如何正确阅读它们。

Answer 1

albums的节点是一个数组，因此您必须访问一个位置，0才能获得第一张专辑。在你的例子中，无论如何只有一张专辑......

string name = stuff.topalbums.album[0].name.ToString();

阅读Json内容并显示它
