Entity Framework - case insensitive Contains?

Question

I want a solution to this problem that does not involve ToUpper or ToLower, as I use in the code below;

var upper = term.ToUpper();
using (var db = this.Data         


        

Answer 1

Just add .ToLower() from upper

 using (var db = this.DataContext)
            {
                return db.Counties
                       .Where(x => x
                       .CountyName.ToLower()
                       .Contains(upper.ToLower())).ToList();
            }
