Comparar Datetime para saber si es el mismo dia solo en c#

[seba123neo]

Hola, algo asi?

Código vb:

Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim i As DateTime = "10/12/2008 10:10:10"
        Dim a As DateTime = "10/12/2008 10:10:10"
 
        If i.Day = a.Day Then MsgBox("Iguales")
    End Sub
End Class
 

saludos.
