Trying to compare tags in mongodb string array, with textbox input c# -

okay have mongodb has collection called videos , in videos have field called tags. want compare textbox input tags on videos in collection , return them gridview if tag matches input textbox. when create new video tags field string array possible store more 1 tag. trying in c#. hope of can thanks!

code creating new video document.

        #region database connection         var client = new mongoclient();         var server = client.getserver();         var db = server.getdatabase("database");         #endregion          var videos = db.getcollection<video>("videos");         var name = txtvideoname.text;         var location = txtvideolocation.text;         var description = txtvideodescription.text;         var user = txtvideousername.text;         string[] lst = txtvideotags.text.split(new char[] { ',' });          var index = videos.count();         var id = 0;          if (id <= index)         {             id += (int)index;         }          videos.createindex(indexkeys.ascending("tags"), indexoptions.setunique(false));          var newvideo = new video(id, name, location, description, lst, user);          videos.insert(newvideo); 

okay here how search method looks have made syntax little diffrent grant winney ansewred.

 var videos = db.getcollection<video>("videos");         string[] txtinput = txtsearchtags.text.split(new char[] { ',' });          var query = (from x in videos.asqueryable<video>()                      x.tags.containsany(txtinput)                      select x); 

this finds videos tags contain tag specified in textbox, assuming mongodb driver can translate valid query.

var videos = db.getcollection<video>("videos")                .asqueryable()                .where(v => v.tags.split(',')                             .containsany(txtvideotags.text.split(',')))                .tolist(); 

make sure you've got using mongodb.driver.linq; @ top.
