Any way to clear all fields in a form at once?

i just started learning C# and i was wondering if it's possible to clear the content of all the textboxes for example in my form.

I know how to clear one by one but it's not practical for me.

thanks!

edit: I found my answer thank you all very much

my code is old school with panels and controls placed in the panels. This is how I went about it WebUtil.ResetControls(PanelMD.Controls);

If you need to clear just what you want you can use "Tag" for that. Just mark your controls with tag "clear":

            foreach (Control c in Controls)
        {
            if (c.Tag == "clear")

            {
                c.Text = string.Empty;
            }
        }

Try this:

Form.Controls.OfType<Textbox>().ToList().ForEach(t => t.Text = "");

You can use the following loop to clear all the textbox objects in your active form:

foreach (Control c in this.Controls) 
{
    if (c.GetType() == typeof(TextBox))
    {
        c.Clear();
    }
}

You can also use the loop inside a function and give it a Boolean return value to test if it was successfuly executed.

I bet you are looking for a solution similar to this one : Foreach Control in form, how can I do something to all the TextBoxes in my Form?

What you want to do is loop through all the controls in the Form, if the control is a TextBox you want to clear it

If you only want to clear TextBoxes you can do it easily like this:

foreach(TextBox tb in this.Controls.OfType<TextBox>())
    tb.Text = string.Empty;

But that will only clear all the TextBoxes that are directly on the Form and not inside a GroupBox or Panel or any other container.

If you have TextBoxes inside other containers you need to recurse:

private void ClearTextBoxes(ControlCollection controls)
{
    foreach(TextBox tb in controls.OfType<TextBox>())
        tb.Text = string.Empty;
    foreach(Control c in controls)
        ClearTextBoxes(c.Controls);
}

Call this like ClearTextBoxes(this.Controls);
