Question

我正在尝试从星星创建矩形并放入文本中，但我无法弄明白。谁能帮我？

string s = Console.ReadLine();
string[] n = s.Split(' ');
int longest = 0;
for (int i = 0; i < n.Length; i++)
{
    if(n[i].Length > longest)
    {
        longest = n[i].Length;
    }
}
for (int i = 1; i <= n.Length + 2; i++)
{
   for (int j = 1; j <= longest + 2; j++)
   {
       if (i == 1 || i == n.Length + 2 || j == 1 || j == longest + 2)
       {
            Console.Write("*");                      
       }
       if (i == 2 && j == 1)
       {
            Console.Write(n[0]);
       }
       else 
            Console.Write("");
    }
    Console.WriteLine();
}
Console.ReadLine();

我可以放一个单词而且很好但是，如果我要更改数组索引的数量，它就无法正常工作。

感谢您的帮助！

多字版

  // please, think about variables' names: what is "n", "s"? 
  // longest is NOT the longest word, but maxLength  
  string text = Console.ReadLine();
  // be nice: allow double spaces, take tabulation into account
  string[] words = text.Split(new char[] { ' ', '\t' },
    StringSplitOptions.RemoveEmptyEntries);

  // Linq is often terse and readable
  int maxLength = words.Max(word => word.Length);

  // try keep it simple (try avoiding complex coding)
  // In fact, we have to create (and debug) top
  string top = new string('*', maxLength + 2);

  // ... and body:
  // for each word in words we should
  //   - ensure it has length of maxLength - word.PadRight(maxLength)
  //   - add *s at both ends: "*" + ... + "*"    
  string body = string.Join(Environment.NewLine, words
    .Select(word => "*" + word.PadRight(maxLength) + "*"));

  // and, finally, join top, body and top 
  string result = string.Join(Environment.NewLine, top, body, top);

  // final output
  Console.Write(result);

对于Hello My World!输入，输出为

 ********
 *Hello *
 *My    *
 *World!*
 ********
