Adding the value (integer) of a variable to a control name (PictureBox) in Windows Forms?

Two ways to do this:

One way is to create an array and index into that instead

var controls = new Control[] { soldOutPB1, soldOutPB2, soldOutPB3 };

controls[index].Visible = true;

Another way is to use the controls collection and specify the control name as a string:

var control = this.Controls[$"soldOutPB1{index}"].Visible = true;
