When you ask a question, make sure you include as much detail as possible. Such as code, the issue you are facing, what you expect the result to be, what .NET version you are using and what platform/environment (if any) are relevant to your question. Upload code here https://paste.mod.gg/ (see $code for more information on how to paste your code)

i understand i wrote most of it but facing a problem which i dont know how to countiue can i screen shot?

Buddy•8mo ago

a problem which is ..? Please avoid screenshotting unless it contains the error

TajabaOP•8mo ago

i wrote a program which drawing shape in the console and it it drawing an endless loop of shapes when i starting it i want to know why

Angius•8mo ago

Just send the code, then

ok wait public static class ScreenSaver { // Start the screen saver public static void Start() { // Loop until any key is pressed while (!Console.KeyAvailable) { // Create a random shape Shape shape = GenerateRandomShape(); // Initialize shape with random values shape.InitWithRandomValues(); // Draw the shape shape.Draw(); // Wait for half a second Thread.Sleep(500); // Show details of the shape shape.ShowDetails(); // Wait for another half a second Thread.Sleep(500); // Clear the console Console.Clear(); } } // Generate a random shape private static Shape GenerateRandomShape() { Random rand = new Random(); int shapeType = rand.Next(1, 6); // Random number between 1 and 5 switch (shapeType) { case 1: return new Square(0, 0, Shape.ConsoleColor.white, 0,0); case 2: return new Circle(0, 0, Shape.ConsoleColor.white, 0); case 3: return new Rectangle(0, 0, Shape.ConsoleColor.white, 0, 0); case 4: return new VerticalLine(0, 0, 0, Shape.ConsoleColor.white, 0); case 5: return new HorizontalLine(0, 0, 0, Shape.ConsoleColor.white, 0); default: return new Square(0, 0, Shape.ConsoleColor.white, 0,0); } } } }

Angius•8mo ago

And the issue is that the loop never stops running, right?

TajabaOP•8mo ago

i dont know its just spamming ** all over the console

maxmahem•8mo ago

does it stop if you hit a key?

TajabaOP•8mo ago

Angius•8mo ago

I assume * is the character you use to draw the shapes

TajabaOP•8mo ago

i think theres a problem with one of the shapes

Angius•8mo ago

Well, I'd say use the debugger to see how it goes

TajabaOP•8mo ago

correct

Angius•8mo ago

Go ahead, then

TajabaOP•8mo ago

i dont know how to use it):

Angius•8mo ago

$debug

TajabaOP•8mo ago

thats whats it doing

Angius•8mo ago

Did you place a breakpoint anywhere?

TajabaOP•8mo ago

i think the problem is in one of the shape classes i have wrote yes

Angius•8mo ago

And did it break the code execution? If so, then step through and see what prints this mass of asterisks

TajabaOP•8mo ago

still coudlnt found it

Angius•8mo ago

Do a test Instead of printing a random shape, try printing them individually' Outside of the loop, even Comment it out See which shape causes issues

TajabaOP•8mo ago

tried to do circle it and thats what it showed de

maxmahem•8mo ago

oh your in VS? Just pause while it's drawing. You should go straight to where the loop is (probably)

Angius•8mo ago

        private int Radius
         {
            get { return Radius; }
            set { if (Radius<12.5) Radius = value; }
        }

        private int Radius
         {
            get { return Radius; }
            set { if (Radius<12.5) Radius = value; }
        }

I needed just the property So, what it does is: when you get a value from Radius, it gets a value from Radius

TajabaOP•8mo ago

oh my english is not that good so forgive me

Angius•8mo ago

To do that, it needs to get a value from Radius, which gets a value from Radius, which gets a value from Radius, which gets a value from Radius, which gets a value from Radius, which gets a value from Radius, which gets a value from Radius, which gets a value from Radius, which gets a value from Radius, which gets a value from Radius, which gets a value from Radius, which gets a value from Radius, which gets a value from Radius, which gets a value from Radius, which gets a value from Radius, which gets a value from Radius, which gets a value from Radius Error: stack overflow If you want to have a property like that, you need a backing field You cannot reference the property in itself, you will get an infinite loop And this will overflow the stack

TajabaOP•8mo ago

got it so how i fix it

Angius•8mo ago

By using a backing field $getsetdevolve

can be shortened to

{
    private int _bar;
    public int Bar {
        get { return _bar; }
        set { _bar = value; }
    }
}

can be shortened to

class Foo

    public int Bar {
        get => _bar;
        set => _bar = value;
    }

{
    private int _bar;
    public int Bar {

See the examples that use _underscored fields Second to last example, in particular That is a property with a backing field

TajabaOP•8mo ago

ok but in my program i get a random value for the radius

Angius•8mo ago

So? The value you give to the property can be whatever Using a backing field does not dictate what value can you give the property We're only fixing this The usage will remain the exact same

TajabaOP•8mo ago

the backing field shot be in the same class?

Angius•8mo ago

How is it in the examples posted above?

TajabaOP•8mo ago

bro i got confused fr

Angius•8mo ago

What's confusing about it?

TajabaOP•8mo ago

i didnt understand what to change in the code and where

Angius•8mo ago

Instead of referencing the property, which references the property, which references the property, which references the property, which references the property, which references the property, which references the property Make a field And reference the field from the property

TajabaOP•8mo ago

ok how to do it

Angius•8mo ago

BAD

class Foo
{
    public int Bar {
        get => Bar;
        set => Bar = value;
    }
}

class Foo
{
    public int Bar {
        get => Bar;
        set => Bar = value;
    }
}

GOOD

class Foo
{
    private int _bar;
    public int Bar {
        get => _bar;
        set => _bar = value;
    }
}

class Foo
{
    private int _bar;
    public int Bar {
        get => _bar;
        set => _bar = value;
    }
}

TajabaOP•8mo ago

oh wait ill do it

 private int radius;
 public int Radius
 {
     get => radius;
     set => radius = value;
 }

 private int radius;
 public int Radius
 {
     get => radius;
     set => radius = value;
 }

like that?

Angius•8mo ago

Yes

TajabaOP•8mo ago

Angius•8mo ago

Except your code has some logic in the serrer

set { if (Radius<12.5) Radius = value; }

set { if (Radius<12.5) Radius = value; }

So you might want to add the same logic here
