asp.net 讀取 豆瓣信息

1.讀取方法

public static string SetUrlToXMLToFile(string url) {

var strXml = "";

var m_uri = new Uri(url);

HttpWebRequest rqst = (HttpWebRequest)WebRequest.Create(m_uri);

rqst.AllowAutoRedirect = true; rqst.ContentType = "xml";

rqst.MaximumAutomaticRedirections = 3;

rqst.UserAgent = "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)";

rqst.KeepAlive = true; rqst.Timeout = 100000;

rqst.Method = "GET";

HttpWebResponse rsps = (HttpWebResponse)rqst.GetResponse();

Stream sm = rsps.GetResponseStream();

Encoding cding = System.Text.Encoding.Default;

if (sm.CanRead) { strXml = new StreamReader(sm, cding).ReadToEnd(); }

return strXml; }

2.返回dataset

public static DataSet CXmlToDataSet(string strXml) {

if (!string.IsNullOrEmpty(strXml))

{ try { DataSet ds = new DataSet();

ds.ReadXml(strXml); return ds; }

catch (Exception e) { throw e; }

finally { //释放资源 } } else { return null; } }

3.綁定數據

System.Data.DataSet oauthentry = HelpOauth.CXmlToDataSet(strXml);

4.代碼調用 string strXml = "http://api.douban.com/movie/subject/1985677";

strXml = HelpOauth.SetUrlToXMLToFile(strXml);

System.Data.DataSet oauthentry = HelpOauth.CXmlToDataSet(strXml); this.GridView1.DataSource = ds.Tables[0]; this.GridView1.DataBind();
