Question

I have about 20 checkboxes on the form. How can I name them to use them later in a for loop for example? A thing such an array checkBox[i].

Answer 1

I am assuming that the controls are being created as part of InitializeComponent(), i.e. it’s done by designer code.

The straightforward approach would be to do this after InitializeComponent is called:

var checkboxes = new[]
{
    checkBox1, // these are the names you have given
    checkBox2, // to the checkboxes in the designer
    checkBox3,
};

A better way would be to use LINQ to put all checkboxes in an array:

var checkboxes = this.Controls.OfType<CheckBox>().ToArray();

However, this will not work recursively and you may have to filter some checkboxes out of the collection if you don’t want all of them to be in the array.
