要从DateTimePicker值获取小时，请使用以下代码:

To get Hour from the DateTimePicker Value use the following code :

Dim _hour As Int32 = DateTimePicker1.Value.Hour

使用以下代码:

Use the following code :

Dim d1 As Int32 = Me.DateTimePicker1.Value.Hour
Dim d2 As Int32 = Me.DateTimePicker2.Value.Hour
If d2 <= d1 Then
    TextBox12.Text = " ON-TIME"
ElseIf d2 > d1 Then
    TextBox12.Text = " DELAY" & (d2 - d1) & "Hours"
End If
