Question

I am using linq to search through a list (user enters query in a textbox).

I want this to be case-insensitive and tried to use IgnoreCase, but I have no idea where to put it…. I know I could use upper or lower, but I would like to hear if anybody has any alternative methods? What would be considered best practise?
Regex did not seem to work either?

        string searchQuery = tbSearchQuery.Text;
        var something= from x in y 
                       where x.Subject.Contains(searchQuery)
                       select x;

Answer 1

Use string.Compare:

    var something= from x in y 
                   where string.Compare(x.Subject, searchQuery, true) >= 0
                   select x;

This can also handle situations where either strings are null.
