loading screen in c#-CodePudding

I'm trying to use a loading gif image for a loading screen in windows form I want the loading screen to show up for 5 seconds I am trying to implement that with thread.sleep() function but the problem was everything stops in the current winForm includes the gif image itself. I want to delay the 5 seconds of loading time with the animated gif image working

CodePudding user response：

You do not want to use Thread.Sleep due to the problems you are describing. Thread.Sleep is almost never the correct answer in a UI program.

What you want to use is a timer that raises an event after 5s and then stops itself, or use await Task.Delay that wraps a timer internally.

You also need to be careful to ensure that your loading window does not become the main window of your application.

Thread.Sleep() blocks the current thread (ie. the UI thread). You can use this wait method which uses a timer.

public void wait(int milliseconds)
{
    var timer1 = new System.Windows.Forms.Timer();
    if (milliseconds == 0 || milliseconds < 0) return;

    timer1.Interval = milliseconds;
    timer1.Enabled = true;
    timer1.Start();

    timer1.Tick  = (s, e) =>
    {
        timer1.Enabled = false;
        timer1.Stop();
    };

    while (timer1.Enabled)
    {
        Application.DoEvents();
    }
}
