Pattern 2 is wrong as per the visual representation desired. I had tried it on the VS2013 compiler.
The code very close to the visual representation is:
            for (int i = 10; i > 0; i--)
    {
        for (int j = i; j >= i/2; j--)
        {
            Console.Write(" ");
        }
        for (int k = 0; k <= 10 - i; k++)
        {
            Console.Write("*");
        }
        Console.Write("\n");
    }
    Console.ReadLine();
