Convert a ushort[] array to a single ushort in C#

Question

Having a ushort array, ushort[] how can I convert the ushort array [44,55] to a single joined ushort 4455 ? The array always has two elements.

ushort[] test = new ushort[2];
test[0] = 44;
test[1] = 55;
// Here I want to convert the ushort[] to a unique ushort value 4455
usortValue = ?
return usortValue;

I was expecting a .join function as String does, but it's not possible with ushort .

Thanks in advance

Answer 1

You can Aggregate, with the predicate being "convert to string, concatenate, and parse back to a ushort", but sooner or later ( sooner! ) you're going to overflow.

ushort[] test = new ushort[2];
test[0] = 44;
test[1] = 55;
var result = test.Aggregate((p,c)  => ushort.Parse((p.ToString() + c.ToString())));

Answer 2

How about converting numbers to string and joining them?

var result =string.Join("",test.Select(x=>x.ToString()));       
Convert.ToUInt16(result);

Demo

Answer 3

ushortValue = Convert.ToUInt16(test[0].ToString() + test[1].ToString());
