Adding multiple variables to a list

Question

I wonder if there is any way to write the following code a lot shorter...

public PictureBox pb1; 
public PictureBox pb2; 
public PictureBox pb3;
..... 
public PictureBox pb50;

And then, is there any way to add all those variables to a list, without having to perform the same ugly code again.

listPB.add(pb1); listPB.add(pb2);...... ListPB.add(pb50);

The method I use is really dumb and I hoped that there were some other way to do it. Thanks for the help!

Answer 1

You can make an ad-hoc collection like this:

PictureBox[] pictureBoxen = {pb1, pb2, pb3, ..., pb50};

and then you can use AddRange on the list to add them

listPB.AddRange(pictureBoxen);

Or if listPB is created on that place, and only contains those variables, you could do:

List<PictureBox> listPB = new List<PictureBox>{pb1, pb2, ..., pb50};

Note that this kind of syntax was only introduced in C#3, in 2008, so it is safe to assume that you are using that or higher.

For C#2 and below, looping is the best I could come up with.
