Search String No Case Sensitive

Hi, i'm tring to do a simple word search in a string, to do so i use: Sentence.IndexOf(WordToSearch);

But if the sentence is "Hello World!", and Word = "hello", it returns -1...

Anyone knows a way to do a no case sensitive search??'

Thanks,
Diego

If you dont need to return the word or sentence with the original formatting hen you could just do Sentence..ToLower().IndexOf(WordToSearch.ToLower()); to make the entire sentence and word lowercase before the search.

But is the IndexOf really case sensitive? Msdn doesen't say.

Yeap!... it's case sensitive, but the problem is that i have to search and make a conditional remove, it's the only one way creating a copy of the Sentence and making all to lower, save the IndexOf position (if the Word was found), and delete it on the original Sentence???

Thanks,

you could make a custom function to do it yourself;

i.e loop through char by char, when you find a match on the first char, check the next, etc.

Yes, it says so:

This method performs a word (case-sensitive and culture-sensitive) search using the current culture.

That's much more easier than creating a custom search function... ;)
