Removing line breaks using C#

Question

I am getting a string from database field named \'Description\' and it has line breaks. It looks like this:

The primary reason is that you are using a verbatim string literal (prefaced with @) and ending it with a literal \. The result is that Replace will end up looking to replace the sequence of characters \, r, \, n,\ rather than a new-line.

This should fix it:

string result = comments.Replace("\r\n", ""); // Not idiomatic

But more idiomatic (and portable) would be:

string result = comments.Replace(Environment.NewLine, "");

(EDIT: This of course assumes that the systems that write to the DB use the same new-line conventions as the systems that read from it or that the translations happen transparently. If this is not the case, you would of course be better off using the actual character sequence you wish to use to represent a new-line.)

By the way, it appears you are trying to get rid of all white-space characters.

In which case you could do :

// Split() is a psuedo-overload that treats all whitespace
// characters as separators.
string result = string.Concat(comments.Split());
