public:
 property System::Windows::Forms::LeftRightAlignment UpDownAlign { System::Windows::Forms::LeftRightAlignment get(); void set(System::Windows::Forms::LeftRightAlignment value); };
public System.Windows.Forms.LeftRightAlignment UpDownAlign { get; set; }
member this.UpDownAlign : System.Windows.Forms.LeftRightAlignment with get, set

範例

下列程式碼範例會使用衍生類別 NumericUpDown ,並設定其衍生自的部分屬性 UpDownBaseThe following code example uses the derived class NumericUpDown and sets some of its properties derived from UpDownBase. 此程式碼會要求您有一個名為和的控制項, NumericUpDown numericUpDown1 ComboBox comboBox1 以及一個名為和的三個控制項,並 comboBox2 CheckBox checkBox1 checkBox2 checkBox2 在表單上建立三個控制項。This code requires that you have a NumericUpDown control named numericUpDown1, two ComboBox controls named comboBox1 and comboBox2, and three CheckBox controls named checkBox1, checkBox2, and checkBox2 created on a form. 將下列專案加入至 comboBox1NoneFixed3DFixedSingleAdd the following items to comboBox1: None, Fixed3D, and FixedSingle. 將下列專案加入至 comboBox2LeftRightCenterAdd the following items to comboBox2: Left, Right, and Center.

程式碼可讓您在執行時間變更屬性值,並查看每個屬性值如何影響微調方塊的外觀和行為。The code allows you to change the property values at run time and see how each affects the appearance and behavior of the spin box.
