Lesson 11 - Finishing the Clock in C# .NET Windows Forms

In the previous lesson, Analog and Digital Clock in C# .NET Windows Forms, we started an application that draws analog and digital clocks. In today's C# .NET tutorial we're going to continue and finish the application.

Digital Clock

Let's move on to drawing the digital clock. We'll draw it just below the center of the clock face and align the text to center. The parameters of the method will be, in addition to the canvas, a time24 parameter, which determines whether we want to display the time in the 24-hour format.

private void DrawDigital(Graphics g, bool time24)
    string time;
    if (time24)
        time = DateTime.Now.ToLongTimeString();
        time = DateTime.Now.ToString("hh:mm:ss");
    SizeF textSize = g.MeasureString(time, font);
    Point textPosition = new Point();
    textPosition.X = center.X - textSize.ToSize().Width / 2;
    textPosition.Y = center.Y + 20;
    g.DrawString(time, font, Brushes.Black, textPosition);

Based on the time24 parameter, we get
