请用C#语句写出代码，谢谢

for (int i = 1; i <= 6; i++)
                {
                    for (int k = 5; k >= i; k--)
                    {
                        Console.Write(" ");
                    }
                    for (int x = 1; x < 2 * i; x++)
                    {
                        Console.Write("*");
                    }
                    Console.WriteLine();
                }

for (int i = 1; i <= 4; i++)
            {
                for (int j = 0; j < 4 - i; j++)
                {
                    Console.Write(" ");
                }
                for (int k = 0; k < 2 * i - 1; k++)
                {
                    Console.Write("*");
                }
                Console.WriteLine();
            }

for (int i = 0; i < 4; i++)
            {
                for(int j=0;j<4+i;j++)
                {
                    if (j < 3 - i)
                        Console.Write(" ");
                    else
                        Console.Write("*");
                }
                Console.WriteLine();
