C# Casting List<ushort> to List<short>

Question

I want to do this

List<ushort> uList = new List<ushort>() { 1, 2, 3 };
List<short> sList = uList.Cast<short>().ToList();

but I get InvalidCastException "Specified cast is not valid."

How can I cast fast and efficient the above collection?

Thank you.

Answer 1

你可以使用ConvertAll：

List<short> sList = uList.ConvertAll(x => (short)x);

Answer 2

List<short> sList = uList.Select(i => (short)i).ToList();
