First of all you must create a DateTime from the text box text. This can be done with DateTime.Parse() or better DateTime.TryParse().

string text  = "06/25/2016";
DateTime date = DateTime.Parse(text);
TimeSpan duration = DateTime.Now - date;
int years = (int)(duration.TotalDays / 365.25);

For an exact result also look at Noda Time like here: Format A TimeSpan with years

var birthDateInput = yourTextBox.Text;
DateTime birthDate;

TimeSpan age;

if(DateTime.TryParse(out birthDate))
{
    age = DateTime.Now - birthDate;
}

When this is done, if the input string is a valid date then age will contain a TimeSpan representing the elapsed time. You'd probably want a little more validation. If the user enters a date in the future then the age will be negative.
