Consider your Post as a paragraph then what do you want to separate from that paragraph?

RegularExpression.

I see ten words, but do you think a program can see that?

Asad_Iqbal 31-Mar-15 14:22pm

on basis of space i can see 9 words.

Nine SPACEs; ten words.

Do hyphenated words, e.g. "world-wide", count as two words? Or as one?

Asad_Iqbal 31-Mar-15 14:45pm

it is counted as one word.

Here's a Regular Expression solution. It still doesn't handle abbreviations (a dot at the end of a "word" that doesn't end a "sentence"), but it does support decimal points within numbers and it doesn't do all that nasssty string splitting X| .

C#

System.Text.RegularExpressions.Regex reg =
  new System.Text.RegularExpressions.Regex
  ( @"(?:^|\G|[.?!])\s*(?'Sentence'(?:\S+\s+){0,4}\S+[.?!])" ) ;

System.Text.RegularExpressions.MatchCollection mat = reg.Matches ( args [ 0 ] ) ;

for ( int i = 0 ; i < mat.Count ; i++ )
{
  System.Console.WriteLine ( mat [ i ].Groups [ "Sentence" ].Value ) ;
}

you need to identify the conditions of how to identify lines in the paragraph and how to separate and count the words in each line. for example;
(note that you need to update the split characters for your requirements)

C#

string input = "aa bb cc dd ee. aa bb. aa bb cc dd. aa bb cc dd ee.";
var lines = input.Split(new[] { '.'}, StringSplitOptions.RemoveEmptyEntries) // get lines
   .Select(sentence =>sentence.Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries)) // get words
   .Where(words=>words.Count()==5)  // filter lines with given word count
   .Select(w=>string.Join(" ", w));  // build line form words

foreach(var line in lines)
   Console.WriteLine(line);

will print

aa bb cc dd ee
aa bb cc dd ee

C#

string text = "a. a. b b. b b. c c c. c c c. d d d d. d d d d. e e e e e. e e e e e.";

string[] sentences = text.Split(new char[] { '.' }, StringSplitOptions.RemoveEmptyEntries);

foreach (string sentence in sentences)
{
    if (sentence.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries).Length == 5)
    {
        System.Diagnostics.Debug.WriteLine(sentence);
    }
}
