试试这个

 在C＃

 private void button1_Click(object sender, EventArgs e)
        {
            if (dateTimePicker1.Value >= DateTime.Now.AddDays(14))
                MessageBox.Show("valid one");
            else
                MessageBox.Show("In Valid one");
        }

 

  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If DateTimePicker1.Value >= Today.AddDays(14) Then
            MsgBox("valid one")
        Else
            MsgBox("In Valid one")
        End If
    End Sub
