Did you try Replace? str1.Replace("\\r\\n", "");

What? ReadLine will remove the line ending, so I don't know why you are asking.

If you only want to remove the \r\n, try Replace:

C#

str1 = sr.ReadLine().Replace("\r\n", String.Empty);
str2 = sr.ReadLine().Replace("\r\n", String.Empty);

If you want to remove all trailing whitespace (if there is any) including \r\n, you can use TrimEnd:

C#

str1 = sr.ReadLine().TrimEnd();
str2 = sr.ReadLine().TrimEnd();

Sure, a 5.
(But it's always better to write string.Empty instead of ""...)

Thanks! I also updated my answer to use String.Empty.

using "" is creating an instance of string each time, but String.empty is not.
