Morse code (also translated as Morse code, Morse code) is a signal code that is on and off, expressing different English letters, numbers and punctuation marks through different arrangements. It was invented by American Alfred Ware in 1837. Morse code is an early form of digital communication, but it is different from modern binary codes that only use two states: zero and one. Its codes include five types: Dots, dashes, pauses between dots and dashes, short pauses between each character (between dots and dashes), medium pauses between each word, and long pauses between sentences.

Morse code C# implementation

Note that only the content in ASCII encoding 127 delimiters such as English/numbers can be used and

Unicode is not supported, but you can modify part of it yourself to support Unicode

Sample code:

public static class MorseCode // 摩尔斯电码(星际穿越)  
   
{  
   
   
    private static volatile string[,] CodeTable =

Use code:

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
