Calculate Month difference between two Dates using C# and VB.net in ASP.Net

Hi Mehram,

Use below code.

C#

string startDate = "01/11/2020";
string endDate = "31/01/2021";
DateTime d1a = DateTime.Parse(startDate, new System.Globalization.CultureInfo("pt-BR"));
DateTime d2a = DateTime.Parse(endDate, new System.Globalization.CultureInfo("pt-BR"));
int months = Math.Abs(d2a.Subtract(d1a).Days / (365 / 12));

VB.Net

Dim startDate As String = "01/11/2020"
Dim endDate As String = "31/01/2021"
Dim d1a As DateTime = DateTime.Parse(startDate, New System.Globalization.CultureInfo("pt-BR"))
Dim d2a As DateTime = DateTime.Parse(endDate, New System.Globalization.CultureInfo("pt-BR"))
Dim months As Integer = Math.Abs(d2a.Subtract(d1a).Days / (365 / 12))
