            string z = "Zulu";
            Console.WriteLine(z);
            break;
    }   
    Console.ReadLine();
}

这是我的代码，但问题是它只输出一个我要输入名称的单词，如“Matt”和输出（Mike Alfa Tango Tango）。

Answer 1

Dictionary

的完美用例

Dictionary<char, string> dDict = new Dictionary<char, string>() {{'a', "Alfa"}, {'b', "Bravo"}, {'c', "Charlie"}, {'d', "Delta"}, {'e', "Echo"}, {'f', "Foxtrot"}, {'g', "Golf"}, {'h', "Hotel"}, {'i', "India"}, {'j', "Juliet"}, {'k', "Kilo"}, {'l', "Lima"}, {'m', "Mike"}, {'n', "November"}, {'o', "Oscar"}, {'p', "Papa"}, {'q', "Quebec"}, {'r', "Romeo"}, {'s', "Sierra"}, {'t', "Tango"}, {'u', "Uniform"}, {'v', "Victor"}, {'w', "Whiskey"}, {'x', "X-Ray"}, {'y', "Yankee"}, {'z', "Zulu"}};
string result = string.Join(" ", "Matt".Select(x => dDict[char.ToLower(x)]));

Answer 2

提取模型，在您的情况下，字母及其名称对应：

private static Dictionary<char, string> s_Alphabet = new Dictionary<char, string>() {
  { 'a', "Alpha"},
   ...
  { 'z', "Zulu"},
};

你可以像

一样轻松

private static string ToAlphabet(string value) {
  return string.Join(Environment.NewLine, value
    .Select(c => s_Alphabet.TryGetValue(c, out var v) 
       ? v               // we know the letter, e.g. 'a', 'e'
       : c.ToString())); // we don't know the letter, e.g. space, full stop
}

如果您希望对A，D，Z等大写字母进行编码，只需添加

char.ToLower()，即：

private static string ToAlphabet(string value) {
   return string.Join(Environment.NewLine, value
     .Select(c => s_Alphabet.TryGetValue(char.ToLower(c), out var v) 
        ? v               // we know the letter, e.g. 'a', 'e'
        : c.ToString())); // we don't know the letter, e.g. space, full stop
 }

Answer 3

我想我看到了你的问题。您需要使用loop来构建字符串。

  Console.WriteLine("Type");
  StringBuilder sb = new StringBuilder();     
  string spell = Convert.ToString(Console.ReadLine());
  foreach (var c in spell.ToUpperInvariant().ToCharArray())
  { //make it uppercase to eliminate case sensitivity
     switch (c) 
     {
        case('A'):  //case now evaluates uppercase chars, so single quotes               
            sb.Append("Alfa "); //no need for the local var but add a space
            break;
        //your other cases omitted for brevity
     }   

  }
  Console.WriteLine(sb.ToString());
  Console.ReadLine();

修改为首先接受整个单词。请注意，在通过开关和开关

运行之前，您需要将字符转换为Upper
