Examples

下列程式碼範例會建立並初始化 NumericUpDown 控制項、設定其中一些通用屬性,並允許使用者在執行時間變更其中一些屬性。The following code example creates and initializes a NumericUpDown control, sets some of its common properties, and allows the user to change some of these properties at run time. 這段程式碼假設已將三個 CheckBox 控制項放在表單上,而且已具現化其 Click 事件的處理常式。This code assumes three CheckBox controls have been placed on a form and handlers for their Click events have been instantiated. DecimalPlacesThousandsSeparatorHexadecimal 屬性是在每個核取方塊的 Click 事件上設定。The DecimalPlaces, ThousandsSeparator, and Hexadecimal properties are set on the Click event of each check box.

Remarks

NumericUpDown 控制項包含單一數值,可以藉由按一下控制項的 [向上] 或 [向下] 按鈕來遞增或遞減。A NumericUpDown control contains a single numeric value that can be incremented or decremented by clicking the up or down buttons of the control. 使用者也可以在值中輸入,除非 ReadOnly 屬性設定為 [true]。The user can also enter in a value, unless the ReadOnly property is set to true.

藉由設定 [DecimalPlaces]、[Hexadecimal] 或 [ThousandsSeparator] 屬性,即可格式化數值顯示。The numeric display can be formatted by setting the DecimalPlaces, Hexadecimal, or ThousandsSeparator properties. 若要在控制項中顯示十六進位值,請將 [Hexadecimal] 屬性設定為 [true]。To display hexadecimal values in the control, set the Hexadecimal property to true. 若要在適當的情況下顯示十進位數中的千位分隔符號,請將 ThousandsSeparator 屬性設為 trueTo display a thousands separator in decimal numbers when appropriate, set the ThousandsSeparator property to true. 若要指定小數點符號後顯示的位數,請將 DecimalPlaces 屬性設定為要顯示的小數位數。To specify the number of digits displayed after the decimal symbol, set the DecimalPlaces property to the number of decimal places to display.

若要指定控制項的允許值範圍,請設定 MinimumMaximum 屬性。To specify the allowable range of values for the control, set the Minimum and Maximum properties. 設定 Increment 值,以指定當使用者按一下向上或向下箭號按鈕時,要遞增或遞減至 Value 屬性的值。Set the Increment value to specify the value to be incremented or decremented to the Value property when the user clicks the up or down arrow buttons. 當使用者透過設定 [Accelerations] 屬性,持續按下向上或向下箭號時,您可以增加控制項在數位之間移動的速度。You can increase the speed that the control moves through numbers when the user continuously presses the up or down arrow by setting the Accelerations property.

呼叫 UpButtonDownButton 方法時,不論是在程式碼中,或是按一下向上或向下按鈕,都會驗證新的值,並以適當的格式將控制項更新為新的值。When the UpButton or DownButton methods are called, either in code or by the click of the up or down buttons, the new value is validated and the control is updated with the new value in the appropriate format. 具體而言,如果 UserEdit 屬性設為 true,則會在驗證或更新值之前呼叫 ParseEditText 方法。Specifically, if the UserEdit property is set to true, the ParseEditText method is called prior to validating or updating the value. 然後,此值會在 MinimumMaximum 值之間進行驗證,並呼叫 UpdateEditText 方法。The value is then verified to be between the Minimum and Maximum values, and the UpdateEditText method is called.

從 .NET Framework 4.6 開始,當 app.config 檔案包含下列專案時,會根據系統 DPI 設定來調整 NumericUpDown 控制項的大小:Starting with the .NET Framework 4.6, the NumericUpDown control will be resized based on the system DPI setting when the app.config file contains the following entry:

<appSettings>  
  <add key="EnableWindowsFormsHighDpiAutoResizing" value="true" />  
</appSettings>
