Max value from list that is smaller than X

Question

How to retrieve int value from List that is biggest number on it but still smaller than X value to which i am comparing.

Value = 10

Example one: List = {1,4,6,8};  => number 8 biggest on list and smaller than 10
Example two: List = {1,15,17,20}; => number 1 biggest on list and smaller than 10

I was trying using Linq but no success so far.

You can just restrict the values you use to get the "Max" by using a Where clause:

return myList.Where(x => x < 10).Max();
