C#

int numberOfWords = 50;
string regexMatch = string.Format(@"^(\w+\b.*?){{" + numberOfWords + "}}");
string firstWords = Regex.Match(result, regexMatch).Value;

This code displays the first 50 words in a string. Now I want to display next 50 words (51st word to 100th word). How do I do it?

There is no way in straight regexes to do that: it is a text processing system, not a record based system (albeit with single words as a record).
The best solution I can come up with is to do the match as above, then use Regex.Replace to remove them and do it again.

Nasty: but it's not what regexes were designed for!

If your requirement is to find each set of 50 words, then I think the Matches method of Regex class can be used as shown below:

C#

string result = "one two three four five six seven eight nine";
int numberOfWords = 2;
string regexMatch = @"(\w+\s*){" + numberOfWords + @"}";
MatchCollection foundWords= Regex.Matches(result, regexMatch);
foreach (Match  match in foundWords)
    Console.WriteLine (match.Value);

//Output

//one two
//three four
//five six
//seven eight
//nine

In the above example I have taken numberOfWords = 2 to illustrate the point. It can be replaced with 50.
