//02. Replace메소드 parameter 활용

* @을 활용한 문자열 리터럴

string normalStr = "This is apple. \nThis is banana.";

string verbatimStr = @"This is apple.
This is banana";

 

* replace 메소드 활용

//parameter 1 : input
//parameter 2 : pattern
//parameter 3: replacement

string answer = str.Replace(my_string, @"a|e|i|o|u", "");
