Under what conditions?

Maybe something like?

            if (this.WindowState == FormWindowState.Minimized)
            {
                this.WindowState = FormWindowState.Normal;
            }

There is one property, ShowInTaskBar.....
If you want to show your UI in taskbar, you can make it true else false.

I try


        if (this.WindowState == FormWindowState.Minimized)
            {
                this.WindowState = FormWindowState.Normal;
            }

But didnt work.

Because when have a problem if the application is minimized i need to restore to the user see the problem.

If the application is not the foreground window then you also need to use the SetforegroundWindow() API to bring it to the front.

So

        if (this.WindowState == FormWindowState.Minimized)
            {
                this.WindowState = FormWindowState.Normal;
                SetforegroundWindow();
            }

?

You have to import it:

        [System.Runtime.InteropServices.DllImport("user32.dll")]
        private static extern int SetForegroundWindow (IntPtr hwnd);

        ...
            if (this.WindowState == FormWindowState.Minimized)
            {
                this.WindowState = FormWindowState.Normal;
                SetForegroundWindow(this.Handle);
            }

Does the taskbar by chance blink?

If not, give us more details about the setup and the conditions under which you need the app to restore.

Why not you use this(Form1_Resize) event:

private void Form1_Resize(System.Object sender, System.EventArgs e)
{
	if (this.WindowState == FormWindowState.Minimized)
        {
		this.WindowState = FormWindowState.Normal;
	}
}

Open in new window


So whenever the window will be minimized it will be restore.
