<span style="font-size:14px;">vb.net中使用DateTimePicker控件，直接生成指定格式的日期内容，</span>

@H_301_3@而且使用控件，还可以省去对其内容的日期check

@H_301_3@

@H_301_3@但是，要设定该控件默认值为空，需要利用程序设定一下：

@H_301_3@

<span style="font-size:14px;">Public Class Form1

Private Sub <span style="color:#ff0000;">Form1_Load</span>(ByVal sender As System.Object,ByVal e As System.EventArgs) Handles MyBase.Load
      DateTimePicker1.Format = DateTimePickerFormat.Custom

      '注意：双引号之间有一个空格
      DateTimePicker1.CustomFormat = </span><span style="font-size:14px;"><span style="color:#ff0000;">" "
</span>
End Sub

Private Sub <span style="color:#ff0000;">DateTimePicker1_CloseUp</span>(ByVal sender As Object,ByVal e As System.EventArgs) Handles DateTimePicker1.CloseUp

       '指定Format"yyyy/MM/dd"，可以避免软件运行系统不同，而显示不同的Format
       DateTimePicker1.Format = </span><span style="font-size:14px;"><span style="color:#ff0000;">"yyyy/MM/dd"
</span>
End Sub

End Class
</span>
