Calculate number of months between two dates in VB.Net

Hi.

I want to calculate number of months between two dates.

I have used the below code but it's showing Month=0.

Dim d1 As DateTime = New DateTime(2017, 1, 3) Dim d2 As DateTime = New DateTime(2017, 31, 3) Dim M As Integer = Math.Abs((d1.Year - d2.Year)) Dim months As Integer = ((M * 12)  + Math.Abs((d1.Month - d2.Month)))

Please suggest any othe code.

Thank you.
