Answer to Question #44003 in C# for Shihab Shahriar Hazari

Question #44003
Hi, I want to draw more than one line in wpf in c#. I want to use array to draw the lines. How can i do it?

I used the following code. I called a method named lets_draw

private void lets_draw()
int i,z;
z = 40;
Line[] line = new Line[20];

line[i].Visibility = System.Windows.Visibility.Visible;
line[i].Stroke = System.Windows.Media.Brushes.Black;
line[i].X1 = z;
line[i].X2 = z;
line[i].Y1 = 40;
line[i].Y2 = 130;
z += 10;
But it showed the following message

"An unhandled exception of type 'System.NullReferenceException' occurred in SkeletalTracking.exe
Additional information: Object reference not set to an instance of an object."
