Description
Replaces an old character or string with a new given character or string.
var
MyString: String;
begin
MyString := 'This is a string.';
Writeln(MyString.Replace('a', 'one'));
Writeln(MyString.Replace('a', '1'));
end.
Output:
This is one string. This is 1 string.
There are four Replace overloaded methods. The first two of them replace only characters while the third and fourth ones replace strings. The ReplaceFlags
parameter is introduced in order for you to use flags such as rfIgnoreCase
or rfReplaceAll
.
