I use Readline() to read a string from a serial port.

But the problem is the string is always appended with "\r" at the end.

I have tried

text.Replace("\r","");

But it is not working.

Any other alternatives ?

Replace doesn’t work in-place. you have to assign the result to a variable.

text = text.Replace("\r","");

or simply

text = text.Trim();
