How can I check my text if it contains any of the array content as words not "texting"?
string text = "some text here";
string[] array1 = { "text", "here" };
string[] array2 = { "some", "other" };
I've found this code on SO how can I adapt it?
string regexPattern = string.Format(@"\b{0}\b", Regex.Escape(yourWord));
if (Regex.IsMatch(yourString, regexPattern)) {
// word found
}
Also is regex the best approach for this work? Or should I use a foreach loop?

I avoid regex until there is no other clean, efficient and readable approach, but that's a matter of taste i think.
Is any of the words in the arrays in the words of a string? You can use Linq:
string[] words = text.Split();
bool arraysContains = array1.Concat(array2).Any(w => words.Contains(w));
foreach with the first array and then a foreach with the second array. So if one word in the first is contained in the string it won't check the second array at all. I thought that you wanted to check both arrays.If you are going to check whether text contains any string in an array like array1 you may try this:
text.Split(' ').Intersect(array1).Any()
Try this code:
string text = "some text here";
string[] array1 = { "text", "here" };
string[] array2 = { "some", "other" };
bool array1Contains = array1.Any(text.Contains);
bool array2Contains = array2.Any(text.Contains);
If your words may be adjacent to quotes, commas etc. rather than just spaces, you can be a bit more clever than just using Split():
var words = Regex.Split(text, @"\W+");
bool anyFound = words
.Intersect(array1.Union(array2), StringComparer.CurrentCultureIgnoreCase)
.Any();
