Convert From Hijri to Georgian date in ASP & C#?

Question

I have two text boxes, One in Hijri Date which I am inserting date in this text box using the calender extender. What I want is that upon selection of date (Hijri Date), the Georgian text box will filled with converted Georgian date using C#.

Does anyone has code for changing the hijri date to georgian date?

You can simply convert between Hijri and Gregorian using the built in CultureInfo class

Imports System.Globalization

Private Sub Convert_From_Hijri_To_Gregorian(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

    Dim arCI As CultureInfo = New CultureInfo("ar-SA")
    Dim hijri As String = Me.TextBox1.Text   '//check if string is valid date first

    Dim tempDate As DateTime = DateTime.ParseExact(hijri, "dd/MM/yyyy", arCI.DateTimeFormat, DateTimeStyles.AllowInnerWhite)
    Me.TextBox2.Text = tempDate.ToString("dd/MM/yyyy")

End Sub

I am not a C# guy but here is my the conversion of the above code to C#

using System.Globalization;

private void Convert_From_Hijri_To_Gregorian(System.Object sender, System.EventArgs e)
{
    CultureInfo arCI = new CultureInfo("ar-SA");
    string hijri = TextBox1.Text;

    DateTime tempDate = DateTime.ParseExact(hijri, "dd/MM/yyyy", arCI.DateTimeFormat, DateTimeStyles.AllowInnerWhite);
    TextBox2.Text = tempDate.ToString("dd/MM/yyyy");


}

I have written this code after reading this article
