So here is my example
string test = "Hello World, I am testing this string.";
string[] myWords = {"testing", "string"};
How do I check if the string test contains any of the following words? If it does contain how do I make it so that it can replace those words with a number of asterisks equal to the length of that?
You can use a regex:
public string AstrixSomeWords(string test)
{
Regex regex = new Regex(@"\b\w+\b");
return regex.Replace(test, AsterixWord);
}
private string AsterixWord(Match match)
{
string word = match.Groups[0].Value;
if (myWords.Contains(word))
return new String('*', word.Length);
else
return word;
}
I have checked the code and it seems to work as expected.
If the number of words in myWords is large you might consider using HashSet for better performance.
"test", which is probably not intended.bool cont = false;
string test = "Hello World, I am testing this string.";
string[] myWords = { "testing", "string" };
foreach (string a in myWords)
{
if( test.Contains(a))
{
int no = a.Length;
test = test.Replace(a, new string('*', no));
}
}
var containsAny = myWords.Any(x => test.Contains(x));
Something like this
foreach (var word in mywords){
if(test.Contains(word )){
string astr = new string("*", word.Length);
test.Replace(word, astr);
}
}
EDIT: Refined
new string('*', word.Length) instead.
