Regex validateWordRegex = new Regex("^\\b(?:\\w|-)+\\b$");
Console.WriteLine(validateWordRegex.IsMatch("word")); // prints True
// Extract words from a string
Regex extractWordsRegex = new Regex("\\b(?:\\w|-)+\\b");
string [] extracted = extractWordsRegex.Matches("Hello, world!")
.Cast<Match>()
.Select(m => m.Value)
.ToArray();
Console.WriteLine(String.Join(",", extracted)); // prints Hello,world
