Hi,
Try like this

private void button1_Click(object sender, EventArgs e)
{
string data = "wwwwwwwwwwww red wwwwwwwwwred ....sabdkjab red jhhkshhkhk red hkhkhhgiuyvvu red...";
string searchItem = "red";
int count = new Regex(searchItem).Matches(data).Count;
MessageBox.Show(count.ToString());
}

Regards,
Iftikar

u can use LINQ expression to count occurrence word in string :
see below code:

string text = @"wwwwwwwtredwwwww red wwwwwwwwwred ....sabdkjab red jhhkshhkhk red hkhkhhgiuyvvu red...";
string searchWord = "red";
string[] source = text.Split(new char[] {'.', '?', '!', ' ', ';', ':', ','},
StringSplitOptions.RemoveEmptyEntries);

var matchQuery = from word in source
where word.ToLowerInvariant() == searchWord.ToLowerInvariant()
select word;

int wordCount = matchQuery.Count();

If you want to count words which include the letters 'red' as well as the word 'red' itself, then just leave the code as Iftikar and Sanjeeb had it originally:

int count = new Regex(searchItem).Matches(test).Count;

If you only want to count the occurrences of the word 'red' and exclude words which include it such as 'tired' and 'bred' then you need to add word boundaries to the regular expression:

int count = new Regex(@"\b" + searchItem + @"\b").Matches(test).Count;

try this sample:

using System;
using System.Text.RegularExpressions;
class Program
{
static void Main(string[] args)
{
string test = "wwwwwwwwwwww red wwwwwwwwwred ....sabdkjab red jhhkshhkhk red hkhkhhgiuyvvu red...";
string searchItem = "red";
int count = new Regex(searchItem).Matches(test).Count;
Console.WriteLine("No of occurence:" + count);
Console.ReadLine();
}
}

output: No of occurence: 5
