. Net to parse the real video download addresses of Major video websites nationwide

This is a software developed a year ago. It is mainly used to analyze the real videos of Major video websites. Of course, it is not implemented by me. I called shuomu for implementation.

Video Information Analysis class:

Using system; using system. collections. generic; using system. LINQ; using system. text; using system. windows. forms; using system. net;/** video analysis * call the data on the official website of shuomu for analysis and processing */namespace websitevideo {public class videoanalysis {public videoanalysis () {// instantiate the video information object videoinfo = new videoinfo ();} private Void analysis (string URL) {// record start time dt1 = datetime. now; try {WebClient mywebclient = new WebClient (); mywebclient. Credentials = credentialcache. defaultcredentials; // gets or sets the network credenbybyte [] pagedata = mywebclient. downloaddata ("http://www.flvcd.com/parse.php? Format = & kW = "+ URL); // download data from the specified website string pagehtml = encoding. default. getstring (pagedata); // If gb2312 is used to retrieve the website page, use this sentence // determine whether the resolution is successful if (pagehtml. indexof ("the expected result is not found")> 0 | pagehtml. indexof ("flvcd does not support resolution of this address currently")> 0) {state = false; return;} // If (pagehtml. indexof ("<input type = \" Hidden \ "name = \" INF \ "value = \" ") <0) {state = false; return ;} // extract data int star = pagehtml. indexof ("<input type = \" Hidd En \ "name = \" INF \ "value = \""); int c = "<input type = \" Hidden \ "name = \" INF \ "value = \"". length; int end = pagehtml. indexof ("\"/> ", star + C); string data = pagehtml. substring (Star + C, end-(Star + C); // data segmentation string [] TMP = data. split ('\ n'); videoinfo. files. addrange (TMP); // Title extraction try {string T1 = "<input type = \" Hidden \ "name = \" FILENAME \ "value = \""; string t2 = "\"/> "; star = pagehtml. indexof (T1) + t1.length; end = pagehtml. indexof (t2, Star); String title = pagehtml. substring (Star, end-star); videoinfo. title = title;} catch {videoinfo. title = "unknown";} // empty data list <string> List = new list <string> (); foreach (string s in videoinfo. files) {If (s! = String. empty) list. add (s);} videoinfo. files = List; // mark as successful state = true; dt2 = datetime. now;} catch (exception e) {dt2 = datetime. now; throw new exception (E. message) ;}} public void go (string URL) {analysis (URL) ;}// status public bool state {set; get ;}public int progress {set; get ;} public videoinfo {set; get;} // record the resolution time // start time, end time datetime dt1, dt2; public String subdatetime {get {// obtain the time difference timespan ts1 = new timespan (dt1.ticks); timespan ts2 = new timespan (dt2.ticks); timespan Ts = ts1.subtract (ts2 ). duration (); Return ts. milliseconds. tostring ();}}}}

Video Information:

Using system; using system. collections. generic; using system. LINQ; using system. text;/** video file information */namespace websitevideo {public class videoinfo {public videoinfo () {files = new list <string> ();} /// <summary> /// title /// </Summary> Public String title {set; get ;} /// <summary> /// format /// </Summary> Public string type {get {// analysis Format String [] TMP = title. split ('.
