.NET / Windows Forms: remember windows size and location

Question

I have a Windows Forms application with a normal window. Now when I close the application and restart it, I want that the main window appears at the same location on my screen with the same size of the moment when it was closed.

Is there an easy way in Windows Forms to remember the screen location and window size (and if possible the window state) or does everything have to be done by hand?

If you add this code to your FormClosing event handler:

if (WindowState == FormWindowState.Maximized) {     Properties.Settings.Default.Location = RestoreBounds.Location;     Properties.Settings.Default.Size = RestoreBounds.Size;     Properties.Settings.Default.Maximised = true;     Properties.Settings.Default.Minimised = false; } else if (WindowState == FormWindowState.Normal) {     Properties.Settings.Default.Location = Location;     Properties.Settings.Default.Size = Size;     Properties.Settings.Default.Maximised = false;     Properties.Settings.Default.Minimised = false; } else {     Properties.Settings.Default.Location = RestoreBounds.Location;     Properties.Settings.Default.Size = RestoreBounds.Size;     Properties.Settings.Default.Maximised = false;     Properties.Settings.Default.Minimised = true; } Properties.Settings.Default.Save(); 

It will save the current state.

Then add this code to your form's OnLoad handler:

if (Properties.Settings.Default.Maximised) {     Location = Properties.Settings.Default.Location;     WindowState = FormWindowState.Maximized;     Size = Properties.Settings.Default.Size; } else if (Properties.Settings.Default.Minimised) {     Location = Properties.Settings.Default.Location;     WindowState = FormWindowState.Minimized;     Size = Properties.Settings.Default.Size; } else {     Location = Properties.Settings.Default.Location;     Size = Properties.Settings.Default.Size; } 

It will restore the last state.

It even remembers which monitor in a multi monitor set up the application was maximised to.
