摩尔斯电码（又译为摩斯密码，Morse code）是一种时通时断的信号代码，通过不同的排列顺序来表达不同的英文字母、数字和标点符号。它由美国人艾尔菲德·维尔于1837年发明。 摩尔斯电码是一种早期的数字化通信形式，但是它不同于现代只使用零和一两种状态的二进制代码，它的代码包括五种： 点、划、点和划之间的停顿、每个字符间短的停顿（在点和划之间）、每个词之间中等的停顿以及句子之间长的停顿。

注意只可以使用英文/数字等ASCII编码127界限符中的内容并

不支持Unicode不过你可以自己修改一部分用于支持Unicode

示例代码：

public static class MorseCode // 摩尔斯电码(星际穿越)     {            private static volatile string[,] CodeTable =          {             {"A",".-"},             {"B","-..."},             {"C","-.-."},             {"D","-.."},             {"E","."},             {"E","..-.."},             {"F","..-."},             {"G","--."},             {"H","...."},             {"I",".."},             {"J",".---"},             {"K","-.-"},             {"L",".-.."},             {"M","--"},             {"N","-."},             {"O","---"},             {"P",".--."},             {"Q","--.-"},             {"R",".-."},             {"S","..."},             {"T","-"},             {"U","..-"},             {"V","...-"},             {"W",".--"},             {"X","-..-"},             {"Y","-.--"},             {"Z","--.."},             {"0","-----"},             {"1",".----"},             {"2","..---"},             {"3","...--"},             {"4","....-"},             {"5","....."},             {"6","-...."},             {"7","--..."},             {"8","---.."},             {"9","----."},             {".",".-.-.-"},             {",","--..--"},             {":","---..."},             {"?","..--.."},             {"\&#39;",".----."},             {"-","-....-"},             {"/","-..-."},             {"(","-.--."},             {")","-.--.-"},             {"\"",".-..-."},             {"=","-...-"},             {"+",".-.-."},             {"*","-..-"},             {"@",".--.-."},             {"{UNDERSTOOD}","...-."},             {"{ERROR}","........"},             {"{INVITATION TO TRANSMIT}","-.-"},             {"{WAIT}",".-..."},             {"{END OF WORK}","...-.-"},             {"{STARTING SIGNAL}","-.-.-"},             {" ","\u2423"}         };                  public static string Enc(string str)         {             int i;             string ret = string.empty;             if (str != null && (str = str.ToUpper()).Length > 0)                 foreach (char asc in str)                     if ((i = Find(asc.ToString(), 0)) > -1)                         ret += " " + CodeTable[i, 1];             return ret;         }                  public static string Dec(string str)         {             int i;             string[] splits;             string ret = string.Empty;             if (str != null && (splits = str.Split(&#39; &#39;)).Length > 0)             {                 foreach (string split in splits)                     if ((i = Find(split, 1)) > -1)                         ret += CodeTable[i, 0];                 return ret;             }             return "{#}";         }                  private static int Find(string str, int cols)         {             int i = 0, len = CodeTable.Length / 2; // len / rank             while (i < len)             {                 if (CodeTable[i, cols] == str)                     return i;                 i++;             };             return -1;         }     }

使用代码:

string encry = MorseCode.Enc("China"); // 把China换成摩尔斯电码  string decry = MorseCode.Dec(encry); //把encry换成明文形式
