Sample Text:

"health-care providers are in the midst of a burgeoning health-care paradigm shift. As the population over age 65 increases and the number of patients in long-term care climbs, the management of chronic disease is now a reality that few debate. Emphasis on disease management is shifting to coordination of care for chronic disease; this is an optimistic observation. The demographic realities of an increasing older population are expected to eclipse 90 million in 2060. This will be nearly 22% of the total population (U.S. Census, 2013)."

I need the "health-care" count value of this text in the above paragraph(ie.How many times the word is present)

C#

public int CountStringOccurrences(string text, string matchword)
    {
	// Loop through all instances of the string 'text'.
	int count = 0;
	int i = 0;
	while ((i = text.IndexOf(matchword, i)) != -1)
	{
	    i += matchword.Length;
	    count++;
	}
	return count;
    }

where string Text is a paragraph and string matchword is the word you want to search

The variable 'pattern is never defined; I think you meant to use 'matchword instead of 'pattern.

There are a lot of ways to do this (most of the ways described here: Counting Lines in a String[^] can be adapted to do it).
But, the simplest to read is probably:

C#

int count = Regex.Matches(inputString, "health-care").Count;

And if you aren't using large amounts of data, or doing it often, that's probably the one I'd go for.

In the general case:
If it is important to exclude similar "words" that include the test word as a subset (e.g., if the test word was "read" and "readers" must be excluded), add the word boundary elements:
int count = Regex.Matches(inputString, @"\bhealth-care\b").Count;
or
int count = Regex.Matches(inputString, string.Concat(@"\b", testWordStringVariable, @"\b")).Count;
