Question

I have a string which contains, lets say word “key” 5 times. Each time I see the word “key” in that string I want to print some text. How can I parse that string, find all “key” words and print the texts accordingly? 5 words “key” – 5 printed texts. This needs to be done in C#.

Thanks in advance.

How about using Regex.Matches:

string input = ...
string toPrint = ...

foreach (Match m in Regex.Matches(input, "key"))
    Console.WriteLine(toPrint);

EDIT: If by “word”, you mean ‘whole words’, you need a different regex, such as:

@"\bkey\b"
