List of Tuple trouble

edit: solved, sorry about this, was due to a typo.

This code.

List<Tuple<Int16, Int16>> a = new List<Tuple<Int16, Int16>>();
Tuple<UInt16, UInt16> b = Tuple.Create<UInt16, UInt16>(4, 2);
a.Add(b);

Produces the following error for a.Add(b)

The best overloaded method match for
'System.Collections.Generic.List<System.Tuple<short,short>>
.Add(System.Tuple<short,short>)'
has some invalid arguments.

In short

List<Tuple<short,short>>.Add(Tuple<short,short>)
has invalid arguments

I can't see how this is.

Tuple<Int16, Int16> and Tuple<UInt16, UInt16> are two different type of tuple.

You are trying to add an UInt16 pair to a list of Int16 pairs. That doesn't work.

You can add an Int16 pair to a list of Int16 pairs:

List<Tuple<Int16, Int16>> a = new List<Tuple<Int16, Int16>>();
Tuple<Int16, Int16> b = Tuple.Create<Int16, Int16>(4, 2);
a.Add(b);

UInt is not an Int

It's telling you exactly the problem and the solution. Try the short instead of unsigned short
