Compare strings with non-English characters?

Question

I need to compare strings for a search mechanism on a web site. I use C#. I tried two ways:

consultants.Where(x => 
    x.Description.ToLower().Contains(v         


        

Answer 1

Thanks to all who offered suggestions, but unfortunately they seem to be irrelevant. As it turns out Contains() has no problem with non-English characters at all. The problem was that the database field in question had html encoded text, so I needed to use HtmlDecode to compare the strings in the controller:

        if (vm.Description != "")
        {
            //HttpUtility.HtmlDecode needed because text in Description field is HtmlEncoded!
            consultants = consultants.Where(x => HttpUtility.HtmlDecode(x.Description).ContainsCaseInsensitive(vm.Description)).ToList();
        }

I discovered this because the Contains() code worked fine when searching another field with non-English characters.
