calculation of age from date of birth

[Julian]

Hi

In VB .Net how do you calculate someones age from their date of birth. I
have the dob in dd/mm/yyyy format and was using date difference, but this
just gives the years with out taking into account whether the person has had
their birth day that year. Ideally I wanted to caclulate it in both years
and in years plus months.

Many thanks

Julian

Look at the method for DateTime.

The Timespan class is what you're looking for

		public string Age
		{
			get 
			{
				if (!dob.HasValue)
					return string.Empty;

				int tmpResult = DateTime.Now.Year - dob.Value.Year;

				if ((DateTime.Now.Month >= dob.Value.Month) 
					&& (DateTime.Now.Day >= dob.Value.Day))
				{
					tmpResult += 1;
				}

				return tmpResult.ToString();
			}
		}
