Question

I have several labels on a form that I would like to be able to reset to “0”.
I have it worked out by referencing each label. I have also used an array and for loop, this seems a little more efficient. Is there a way to reference each label name by using the for variable and constructing a string the evaluates to the label name without an array?

Like this:

            for (int x = 0; x < 6; x++)
            lbls[x].Text = "0";

Here is my code:

        // Clear form labels
    private void btnClear_Click(object sender, EventArgs e)
    {
        Label[] lbls = new Label[]
        {
            lbl1, lbl2,lbl3,lbl4,lbl5,lbl6
        };

        for (int x = 0; x < 6; x++)
            lbls[x].Text = "0";

        //lbl1.Text = "0";
        //lbl2.Text = "0";
        //lbl3.Text = "0";
        //lbl4.Text = "0";
        //lbl5.Text = "0";
        //lbl6.Text = "0";
    }

If you don’t have other labels:

this.Controls.OfType<Label>()

will give you an IEnumerable of all the labels on your form, and then you can use Simons code:

this.Controls.OfType<Label>().ToList<Label>().ForEach(l => l.Text = "0");
