Two things:
1) use the respective split option to not place the empty parts into the list
2) allow the split function to take char.IsWhitespace(c) as separator
See remarks on null parameter in String.Split Method (Char[], StringSplitOptions)[^].

C#

char[] takeWhiteSpaceSeparators = null;
int wordCount = paragraph.Split( takeWhiteSpaceSeparators
                               , StringSplitOptions.RemoveEmptyEntries
                               )
                               .Length;

You can try using this code for counting the words,

C#

// Method returns an integer and gets a string paragraph
int GetWords(string paragraph) {
// It returns the total number of words
return (
        // Splits the paragraph at every occurance of empty string
        paragraph.Split(new string[] {" "}, 
        // Spliting options let you omit the empty words, like " "
        StringSplitOptions.RemoveEmptyEntries).Length
       );
}

This would return the total number of words in the paragraph or what so ever the string is. To test this program logic, you can use this fiddle: https://dotnetfiddle.net/E1JIy2[^]. For more on this Split method signature and other details, see this MSDN document[^].

Solution 1

Use the string split method and more accurately this overloaded version is probably the best: see here[^]

You´ll need:

string [] seperator = { " " };
string [] words = Paragraph.Split(seperator, StringSplitOptions.RemoveEmptyEntries);
int nrofwords = words.Length;

hope this helps.

You are not taking tabs as separators as the OP has in his code.
I think any whitespace should be considered as with char.IsWhiteSpace(c).

You can add the tab in the seperator array as well as newlines and other whitespace characters ;-)

Why reinventing the wheel?
See MSDN documentation on whitespace characters:
Char.IsWhiteSpace Method:
[...]White space characters are the following Unicode characters:

- Members of the SpaceSeparator category, which includes the characters SPACE (U+0020), OGHAM SPACE MARK (U+1680), EN QUAD (U+2000), EM QUAD (U+2001), EN SPACE (U+2002), EM SPACE (U+2003), THREE-PER-EM SPACE (U+2004), FOUR-PER-EM SPACE (U+2005), SIX-PER-EM SPACE (U+2006), FIGURE SPACE (U+2007), PUNCTUATION SPACE (U+2008), THIN SPACE (U+2009), HAIR SPACE (U+200A), NARROW NO-BREAK SPACE (U+202F), MEDIUM MATHEMATICAL SPACE (U+205F), and IDEOGRAPHIC SPACE (U+3000).

- Members of the LineSeparator category, which consists solely of the LINE SEPARATOR character (U+2028).

- Members of the ParagraphSeparator category, which consists solely of the PARAGRAPH SEPARATOR character (U+2029).

- 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).
