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","----."},

{".",".-.-.-"},

{",","--..--"},

{":","---..."},

{"?","..--.."},

{"\'",".----."},

{"-","-....-"},

{"/","-..-."},

{"(","-.--."},

{")","-.--.-"},

{"\"",".-..-."},

{"=","-...-"},

{"+",".-.-."},

{"*","-..-"},

{"@",".--.-."},

{"{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(' ')).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
