🎯 How to center a WPF app on screen? 🖥️

Having your WPF (Windows Presentation Foundation) app perfectly centered on the screen creates a visually pleasing experience for your users. But, figuring out the values to set for myWindow.Left and myWindow.Top can be a bit tricky. Don't worry, we've got you covered! In this article, we'll guide you through the process and provide easy solutions to this common problem. Let's get started! 💪

🗺️ Getting the screen resolution in WPF

The first thing our reader mentioned was finding the screen resolution. In WPF, we don't have a direct equivalent to System.Windows.Forms.Screen.PrimaryScreen. So how do we get the screen resolution?

To accomplish this, we can utilize the System.Windows.SystemParameters class. Specifically, we'll use the PrimaryScreenWidth and PrimaryScreenHeight properties to obtain the necessary screen dimensions. Let's take a look at the code snippet below:

double screenWidth = SystemParameters.PrimaryScreenWidth;
double screenHeight = SystemParameters.PrimaryScreenHeight;

With these two lines of code, we have obtained the screen width and height, respectively.

💡 Centering your WPF app on the screen

Now that we have the screen resolution, let's proceed with centering our WPF app.

To center your WPF window on the screen, you'll need to set the myWindow.Left and myWindow.Top properties to half the difference between the screen dimensions and your window's dimensions. This process involves some simple calculations.

Here's an example snippet that demonstrates this concept:

double windowWidth = myWindow.Width;
double windowHeight = myWindow.Height;
double left = (screenWidth - windowWidth) / 2;
double top = (screenHeight - windowHeight) / 2;

myWindow.Left = left;
myWindow.Top = top;

By setting the myWindow.Left and myWindow.Top properties according to the calculated values, your WPF app will be perfectly centered on the screen when it starts up! 🎉
