Question

I have a simple for loop as follows:

for (int i = 0; i > 20; i++)
{

}

Now I have 20 labels (label1, label2, label3 and so on..)

I would like to do something like:

for (int i = 0; i > 20; i++)
{
    label[i].Text = String.Empty;
}

What is the easiest way to accomplish this?

Answer 1

If your labels are placed on one container, say Form, you may do the following:

foreach(Label l in this.Controls.OfType<Label>())
{
    l.Text = string.Empty;
}

Same for any other container, say, Panel or GroupBox, just replace this with the name of the container (panel1.Controls, etc.)
