How to filter a list for multiple startswith criteria?

If I filter a list for multiple criteria I can do this like this:

string[] criteria = { "a1", "b1" };
var res = reslist.Where(x => criteria.Contains(x.book)).ToList();

Now I would like to do sth like this:

string[] criteria = { "a", "b" };
var res = reslist.Where(x => criteria.ContainsStartsWith(x.book)).ToList();

Obviously this doesnt exists. How can I check through a criteria list with startswith values?

Use below 

var res = reslist.Where(x => criteria.Any(s=>s.StartsWith(x.book) || criteria.Contains(x.book)).ToList();

You could use Any extension method .

var res = reslist.Where(x => criteria.Any(s=>s.StartsWith(x.book)).ToList();
