ممنون

Console.WriteLine("---------------------------");
for (int i = 0; i <= 5; i++)
{
for (int j = 0; j < i; j++)
{
Console.Write("*");
}
Console.WriteLine();
}

for (int i = 5; i >= 1; i--)
{
for (int j = 0; j < i; j++)
{
Console.Write("*");
}
Console.WriteLine();
}
Console.WriteLine("---------------------------");

int n = 23;

{
Console.Write("*");
}
else
{
Console.Write(" ");

} Console.WriteLine();
}
Console.ReadLine();
این یکی رو خودت امتحان کن تا شکلشو ببینی

private void Form1_Paint(object sender, PaintEventArgs e)
{
int xc = 200, yc = 200, rad = 100, i, j, n = 10;
double[] x = new double[20];
double[] y = new double[20];
Graphics g1 = this.CreateGraphics();
Color c1 = Color.Black;
Pen p1 = new Pen(c1, 2);
for (i = 0; i < n; i++)
{
x[i] = xc + rad * System.Math.Cos(360 / n * i * Math.PI / 180);
y[i] = yc + rad * System.Math.Sin(360 / n * i * Math.PI / 180);
}
for (i = 0; i < 10; i++)
for (j = 0; j < 10; j++)
g1.DrawLine(p1, (int)x[i], (int)y[i], (int)x[j], (int)y[j]);
}
