Calculate Age in Years using C# or VB.NET

I was recently checking out some scripts to calculate the Age of a person in years and came across a simple piece of code shared by NeilPric. Here’s the code for your reference:

C#

static void Main(string[] args)
{
    DateTime dob = DateTime.Parse("04/24/1979");

    int ageInYrs = DateTime.Now.Year - dob.Year;
    if (DateTime.Now.Month < dob.Month
         (DateTime.Now.Month == dob.Month &&
          DateTime.Now.Day < dob.Day))
        ageInYrs--;
    Console.WriteLine(ageInYrs);
    Console.ReadLine();
}

VB.NET

Sub Main(ByVal args() As String)
   Dim dob As Date = Date.Parse("04/24/1979")

   Dim ageInYrs As Integer = Date.Now.Year - dob.Year
   If Date.Now.Month < dob.Month _
    OrElse (Date.Now.Month = dob.Month AndAlso Date.Now.Day < dob.Day) Then
            ageInYrs -= 1
   End If
   Console.WriteLine(ageInYrs)
   Console.ReadLine()
End Sub

OUTPUT
