C# String.Split with TrimEntries option returbs zero length entries

Question

The following code reads in the file OK. It splits the text into several lines without end-of-line terminators OK. But even though the Split has the TrimEntries option, it still returns several lines of zero length. Why? How to remove zero-length entries with Split? Is this another MS bug?

                    char[] charSeparators = new char[] { '\x0A', '\x0C', '\x0D' };
                    using (StreamReader sr = new StreamReader(fileNm))
                    {
                        content = sr.ReadToEnd();
                        linesIn = content.Split(charSeparators, 
                            StringSplitOptions.RemoveEmptyEntries
                            & StringSplitOptions.TrimEntries);
                        sr.Close();
                    }

Just a guess but did you mean to bitwise OR these instead of AND?

StringSplitOptions.RemoveEmptyEntries & StringSplitOptions.TrimEntries
