A list of multiple data types?

Question

I have two classes as such:

public class MachineLine
{
    public double X1;
    public double Y1;
    public double X2;
    public double Y2;
    public dou         


        

Answer 1

Now, with C# 7.0 is as easy as using a Tuple:

public List<(MachineLine line, MachineCircle circle)> machineList { get; set; }

To add data (Note the (( and )), one parenthesis for params and another one to indicate tuple):

MachineLine theLine = ...;
MachineCircle theCircle = ...;

machineList.Add((theLine, theCircle));

To get data:

MachineLine ml = emailSender.ElementAt(3).line;
MachineCircle mc = emailSender.ElementAt(3).circle;

As easy as one, two, three!
