Is there any way of stopping string.Trim()
from removing an FF character?
I am parsing a file wanrt to be able to tell the difference between an empty line with just an FF char, a line of spaces with an FF char, and a line of "data" with an FF char.
However, if I test string.Trim() == string.Empty
then it returns true for all of:
"\f"
" "
" \f"
e.g. It is also trimming the \f
out of the string?
Note: I can test for the \f
using Regex, but interested in why the trim removes the \f as well?
From the MSDN:
string.trim
White-space characters are defined by the Unicode standard. The Trim() method removes any leading and trailing characters that produce a return value of true when they are passed to the Char.IsWhiteSpace method.

From Char.IsWhiteSpace
White space characters are the following Unicode characters: The characters CHARACTER TABULATION (U+0009), LINE FEED (U+000A), LINE TABULATION (U+000B), FORM FEED (U+000C), CARRIAGE RETURN (U+000D), NEXT LINE (U+0085), and NO-BREAK SPACE (U+00A0).

That's why it's getting stripped out.
Hope this helps
