C# check MaskedTestBox empty

Question

How can I check if a masked text box in C# is empty, i.e. the user has not entered anything?

My text box only allows 4 numbers to be input.

Thanks

You can check if Text property of the MaskedTextBox is null or String.Empty

if (String.IsNullOrEmpty(maskedTextBox1.Text))
{
    //no input
}
