Using Name or ID for Controllers?!

Hello everyone.
i writing some codes and need to make some Buttons in Code-Behind.
for loop would do that, but i can not set any Name or ID for Buttons,
and because of that, i cant define any property for each of Buttons separately.
this is my code:

for (int i=1 ;i<=10; i++)
{

            Button but_Icon = new Button
            {
                HeightRequest = 80,
                Text = "",
                VerticalOptions = LayoutOptions.Start,
                HorizontalOptions = LayoutOptions.Center
                Name = "but_Icon" + i.toString();     //this works on C# but not works here!
            }

            Label lab_Icon = new Label
            {
                Text = "Application NO." + i.ToString(),
                VerticalOptions = LayoutOptions.Start,
                Font = Font.SystemFontOfSize(NamedSize.Medium,FontAttributes.Italic),
                HorizontalOptions = LayoutOptions.Center

            };

            if (i % 2 == 0)
            {
                grid.Children.Add(but_Icon, 1, i - 2);
                grid.Children.Add(lab_Icon, 1, i - 1);
            }
            else
            {
                grid.Children.Add(but_Icon, 0, i - 1);
                grid.Children.Add(lab_Icon, 0, i);
            }

}

i know can use x:Name in XAML, but not works for something like this code.
any suggestion i appreciate.
