Datetime from date and time

Question

Hi

I have a DatetTime EventDate that only contains date value and another DateTime EventStartTime that only contains time value. How can I merge the two into another DateTime EventStart to contain both date and time values?

Thanks

Regards

If you look at the constructors of the DateTime Structure there are a few that will create a new Date with the specified year, month, day, hour, minute, and second.   You could create a New Date and specify the year, month, and day from one of your dates and the hour, minute, and second from the other date.

 As an example, place 2 DateTimePicker controls on a form and set the Format property of DateTimePicker2 to Time and try this code.

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim dDate As Date = DateTimePicker1.Value
        Dim dTime As Date = DateTimePicker2.Value

        Dim d As New Date(dDate.Year, dDate.Month, dDate.Day, dTime.Hour, dTime.Minute, dTime.Second, DateTimeKind.Local)
        MessageBox.Show(d.ToString)
    End Sub
End Class

If you say it can`t be done then i`ll try it

If DateTimePicker1 has the date and DateTimePicker2 has the time then an alternative to IronRazer's approach.

        'combined DateTime
        Dim d As DateTime = New DateTime(DateTimePicker1.Value.Date.Ticks) 'get the date
        d = d.Add(DateTimePicker2.Value.TimeOfDay) 'add the time
