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

Use

String.Equals(c, vm, StringComparison.OrdinalIgnoreCase)

or

c.IndexOf(vm, StringComparison.OrdinalIgnoreCase)

Ordinal means Unicode, byte-per-byte, culture-independent comparison.
