C# Get text out of input textbox Selenium

[Daryl Bennett]

Hi, 
I'm using Firefox and C# to develop my Selenium script. I have a basic question about getting text out of an input field;

I have a textbox named address that looks like this:

 <td><input id='address' class='contact' placeholder= 'Please Enter Address' required type='text' name='address'
         value='123 University Ln'/></td>

And here is the c# code that i use to try to retrieve the text value. (Which is '123 University Ln' Which was inputted by a user)

            address = driver.FindElement(By.Id("address"));

             Console.WriteLine("DEBUG address: " +address.Text);

address.Text returns empty... How do I get the text from the text inputbox?

Thanks, Daryl

address = driver.FindElement(By.Id("address")).GetAttribute("value");
