C#实现一张塔松叶

前段时间,Insus.NET有实现一组字符串在输出时,靠左或靠右对齐。《输出的字符靠右对齐http://www.cnblogs.com/insus/p/7953304.html

现在Insus.NET参考此方法,实一张塔松叶,实现之前,先练习一下,输出半张:

 

 public void WriteTriangle()
        {
            char symbol = '*';
            int star = 13;
            for (var i = 1; i <= star; i++)
            {
                string s = new string(symbol, i);
                s = s.PadLeft(star, ' ');
                Console.WriteLine(s);
            }
        }      
Source Code

 

运行代码,看看输了啥样子?

 

 

目标实现50%。接下来,完成另外一边,Insus.NET创建另外一个方法:

 public void WritePineTree()
        {
            char symbol = '*';
            int star = 13;

            Console.WriteLine(symbol.ToString().PadLeft(star + 1, ' '));
            for (var i = 1; i <= star; i++)
            {
                string s = new string(symbol, i);
                string left = s.PadLeft(star, ' ');
                string right = s.PadRight(star, ' ');
                Console.WriteLine(left + symbol.ToString() + right);
            }
        }
Source Code

 

在控制台,执行代码:
