C＃替换字符串中的特殊字符

Question

This used to be easy in VB but I'm completely stumped in c# VS2010.

I am receiving data form a serial port. At the end of each line there is a special character which indicates EndOfText. If you look at it in the terminal window it looks like a little L-shaped bracket. That character is the ASCII "03"

I need to replace that character with a crlf ("\\r\\n").

I have tried the following and it's throwing "Invalid Argument" errors:

 RxString = RxString.Replace((char) 03, "\r\n");

I can trim the end character and then perform and append of the CRLF "\\r\\n" but would rather do it properly in one pass.

Answer 1

There's no overload of string.Replace taking a char then a string . This should work though:

RxString = RxString.Replace("\u0003", "\r\n");
