Enabling many textBoxes at the same time

I have 10 textBoxes in one form and I have a checkBox.

I would like this checkBox to control if the textBoxes are enabled or not. I know I can do it textBox1.Enabled = true; textBox2.Enabled = true; etc but is there any way to do it in one line or shorter?

More code golf (it's technically one line): Assumes the TextBoxes are directly contained by the Form

    public Form1()
    {
        InitializeComponent();
        checkBox1.Checked = true;
        checkBox1.CheckedChanged += (sender, e) => { foreach (TextBox tb in this.Controls.OfType<TextBox>()) { tb.Enabled = ((CheckBox)sender).Checked; } };
    }

var cntrlCollections = GetAll(this,typeof(TextBox));

foreach (Control ctrl in cntrlCollections)
{
  ctrl.Enabled = checkBox.Checked;
}

The cleanest way is to create an array of TextBox's first, and then iterate over it. 

var textBoxes = new TextBox[] { ... };

...

foreach(var tb in textBoxes)
{
    tb.Enabled = true;
}

But you asked for a solution "in one line or shorter". To do it in one line, you'd have to do this:

new [] { textBox1 ... }.ToList().ForEach(tb => tb.Enabled = true);

or

new [] { textBox1 ... }.AsParallel().ForAll(tb => tb.Enabled = true);

You can do this in one line of Code as follows,

You place all the text boxes inside a group box or a panel. 

Pnl.Enabled = Chk.Checked

private void ToggleAllTextBoxControls()
{
    foreach (Control c in this.Controls)
        if (c Is TextBox)
             c.Enabled = chkEnable.Checked;
}

This will iterate through all controls on the form and enable it if it's a TextBox and the checkbox is checked.
