NumericUpDown控件ValueChanged事件获取的数值是上一次数据的问题解决

Winform 上添加 NumericUpDown 控件  事件代码如下：

Private Sub NumericUpDown_Line_ValueChanged(sender As System.Object, e As EventArgs) Handles NumericUpDown_Line.ValueChanged

For Each serie As Series In Chart_View.Series
int num = NumericUpDown_Line.Text
Next

End Sub

这么写代码的话，架设当前控件值是3，点击增加后，正常应该获取到4的，可是通过.Text属性还是获取到3.
正确写法如下：

Private Sub NumericUpDown_Line_ValueChanged(sender As System.Object, e As EventArgs) Handles NumericUpDown_Line.ValueChanged

For Each serie As Series In Chart_View.Series
int num = NumericUpDown_Line.Value
Next

End Sub
将.Text 缓冲.Value
自己Mark下。
