直接用循环输出即可。

using System;
 
namespace ConsoleDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            for (int i = 9; i > 0; i -= 2)
            {
                for (int j = 9; j > i; j -= 2)
                    Console.Write(" ");
                for (int j = 0; j < i; j ++)
                    Console.Write("*");
                Console.Write("\n");
            }
            Console.ReadKey();
        }
    }
}

namespace xx{
class xx{
static void Main(){
Console.WriteLine("本程序用于倒金字塔的输出");
Console.WriteLine("请输入倒金字塔的塔高：");
int hang=Convert.ToInt32(Console.ReadLine());
int k=hang,i=1;
while(i<=hang){
int j=1;
while(j<=k-1){
Console.Write("\0");
j++;
}
int x=1;
while(x<=2*i-1){
Console.Write("*");
x++;
}
Console.Write("\n");
i++;
k--;
}
}
相信我绝对没问题

给你个菱形 自己看看
把 system.out.print(); 改成 Console.Write();就好了

for (int j = 1; j <= 10; j++)
{

for (int z = 1; z <= 10 - j; z++)
{
System.out.print(" ");

}
for (int i = 1; i <= 2 * j - 1; i++)
{
System.out.print("*");
} System.out.println();
}

for (int j = 1; j <= 10; j++)
{
for (int z = 1; z <= j; z++)
{
System.out.print(" ");
}
for (int i = 19 - j * 2; i >= 1; i--)
{
System.out.print("*");
} System.out.println();
}
}
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace sanjiao
{
class Program
{
static void Main(string[] args)
{
for (int i = 1; i <= 6; i++)
{
for (int j = i; j <=6; j++)
{
Console.Write("*");
}
Console.WriteLine(" ");

补充回答：

以下各种都有了，是控制能程序

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace sanjiao
{
class Program
{
static void Main(string[] args)
{
for (int i = 1; i <= 6; i++)
{
for (int j = i; j <=6; j++)
{
Console.Write("*");
}
Console.WriteLine(" ");
}

Console.WriteLine();

for (int i = 1; i <= 6; i++)
{
for (int j = 1; j <= i; j++)
{
Console.Write("*");
}
Console.WriteLine(" ");
}

for (int i = 1; i <= 6; i++)
{
for (int j = i; j <= 6; j++)
{
Console.Write(" ");
}
for (int j = 1; j <= i; j++)
{
Console.Write("*");
}
Console.WriteLine(" ");
}

for (int i = 1; i <= 6; i++)
{
for (int j = 1; j <= i; j++)
{
Console.Write(" ");
}
for (int j = i; j <= 6; j++)
{
Console.Write("*");
}
Console.WriteLine(" ");
}

for (int i = 1; i <= 6; i++)
{
for (int j = 1; j <= i; j++)
{
Console.Write(" ");
}

for (int j = i; j <= 6; j++)
{
Console.Write(" *");
}
Console.WriteLine(" ");
}

Console.ReadKey();
}

}
}
