c# - Switching images in picturebox -


in windows forms application have display few (or more) images in 1 picturebox - need change every 10 seconds (or similar).
first retrieve images database , display them in specific picturebox.
every image has unique id , 1 image works fine.

i have sql database (sql server 2014) , use linq.

public void displayadds(imagead img, int imgid)     {           using (var dbcontext = new linqclassesdatacontext())         {              var table = t in dbcontext.imageads                         t.id == imgid                         select t;              img.image = table.single().image;              picturebox1.image = bytearraytoimage(img.image.toarray());         }     }

in end 'displaying' has in foreach loop, because have list of ints (list), display images selected ids.

i tried using threads, or refreshing, , simple loop didn't work:

for(int i=0; i<5; i++)  {     displayadds(img, i);    }

here other methods tried , didn't work. 

public void displayad(imagead img)     {         int = 1;          using (var dbcontext = new linqclassesdatacontext())         {             while (true)             {                 var table = t in dbcontext.imageads                             t.id ==                             select t;                  img.image = table.single().image;                  picturebox1.image = bytearraytoimage(img.image.toarray());                  thread.sleep(1000);                 i++;                  if (i >= 15)                     = 1;             }          }     }       public void displaylist(imagead img)     {         using (var dbcontext = new linqclassesdatacontext())         {             (int = 0; < 5; i++)             {                 var table = t in dbcontext.imageads                             t.id ==                             select t;                  img.image = table.single().image;                 // picturebox1.image = bytearraytoimage(img.image.toarray());                  picturebox pb = new picturebox();                 //254,15                 pb.location = new point(254, 15);                 pb.size = new size(310, 367);                // pb.borderstyle = borderstyle.fixed3d;                 pb.image = bytearraytoimage(img.image.toarray());                 pb.cursor = system.windows.forms.cursors.hand;                 this.controls.add(pb);                 pb.bringtofront();                  thread.sleep(1000);              }         }     }

i found way far works fine. turned out on stackoverflow , unfortunately hadn't found earlier: changing image in picture box rapidly

and used this:

     var table = t in dbcontext.imageads t.id == select t;                     img.image = table.single().image;                      picturebox1.image = bytearraytoimage(img.image.toarray());                     picturebox1.refresh();                     await task.delay(1000);
