Check whether an array is a subset of another

Question

Any idea on how to check whether that list is a subset of another?

Specifically, I have

List t1 = new List { 1, 3, 5 };
L

If you are unit-testing you can also utilize the CollectionAssert.IsSubsetOf method :

CollectionAssert.IsSubsetOf(subset, superset);

In the above case this would mean:

CollectionAssert.IsSubsetOf(t2, t1);
