I am writing a theater mode section in music player. The requirements is to loop through a folder containing images of any type(png, jpeg, gif) and show in a picture box with 5 seconds delay for images of type (png,jpeg) and delay time for gif should be the actual gif time duration. Also there should be fade transition between images when switch from one image to another in a single picture box. All need to be done when software is idle lets say for 60 seconds
Problem
Currently the playing song directory has 'img' folder containing 3 png images and 3 gif. The first attempt to read Helper.theaterImagesInfo.ToList() works pretty well
foreach (var img in Helper.theaterImagesInfo.ToList())
It starts to display 3 png images with 5 seconds delay and gif images with the actual gif duration delay. but if i click picturebox to close theaterform as soon as the form is opened again after 60 seconds of idle state of software and loop continue to iterate again. The default image is shown with starting 2 png images from 'img' folder the 3rd png is skipped and then 4th gif starts to play for few seconds not the actual gif duration and continued in wrong order as well as incorrect delay, Seems like while loop is always running in background. therfore it becomes choppy.
Desired Solution Whenever i play song theaterform should be displayed and start to show images from folder ( in the same sequence and delay) even if the theaterform is opened again after 60 seconds if the song is still playing. Also if there is a way to show fade when changing image in a single picturebox

CodePudding user response：
Most likely you just need to break out of that foreach loop:
foreach (var img in Helper.theaterImagesInfo.ToList())
{
if (img.IsAnimated)
{
try
{
this.PictureBox1.Image = img.ImageHere;
await Task.Delay(img.durationInMilliseconds);
}
catch { }
}
else
{
try
{
await Task.Delay(img.durationInMilliseconds);
if (this.x == 1) {
this.PictureBox1.Image = img.ImageHere;
}
}
catch { }
}
if (this.x == 0) {
break; // exit the for loop early
}
}
