I have created a 100 buttons on Windows Forms using Toolbox and I have given them a specific name for each row and column for example the first row is called A and first column is called 1 , the last row ends with the letter J and the last column ends with the number 10 . So it appears as a 10x10 array. What I am trying to do is add those buttons into a list either with a loop . On properties under design I have given them their equivalent name to make it easier. What would be the best way to add them into a list ?

They're already in a "list" in that to appear on the Form they must be a member of some existing Control's .Controls collection, and you can query it. Suppose they're just straight on the Form, not in a Panel etc:

this.Controls.OfType<Button>()

If you truly want a List<Button>, add .ToList() onto the end

If you have other buttons on the Form that you don't want being returned, then pick on something common about those buttons you do want, like "they all have a two-character name":

this.Controls.OfType<Button>().Where(b => b.Name.Length == 2)

Of course, if you've also stuck a Button called OK, then this is defeated - but the "something common about them that no other button has" is something you can influence - rename your OK button if it's being picked up accidentally

If they're in their own Panel, it could be a good way of segregating them from other Buttons:

thePanelName.Controls.OfType<Button>()
