C# WinForm - loading screen

C# WinForm - loading screen

To create a loading screen in a WinForms application using C#, you can create a new form that will act as the loading screen and display it while your main form loads.

Here are the steps to create a loading screen:

  • Create a new form in your project called LoadingScreenForm.

  • Add controls to the form to display a loading message or animation, such as a progress bar or an animated GIF.

  • In your main form's constructor, create a new instance of the LoadingScreenForm and display it using the Show() method:

public MainForm() { InitializeComponent(); // Show the loading screen form LoadingScreenForm loadingScreen = new LoadingScreenForm(); loadingScreen.Show(); // Load the main form's data or perform other time-consuming tasks LoadData(); // Close the loading screen form loadingScreen.Close(); }

In this example, we create a new instance of the LoadingScreenForm and show it using the Show() method. We then perform any time-consuming tasks, such as loading data, in the LoadData() method. Finally, we close the loading screen form using the Close() method.

  • Build and run your application to see the loading screen in action.

By following these steps, you can create a loading screen in your WinForms application to provide feedback to the user while your main form loads or performs other time-consuming tasks. You can customize the appearance of the loading screen and add additional controls as needed.
