注解

NumericUpDown 控件包含单个数值,通过单击控件的向上或向下按钮可以增加或减少该值。A NumericUpDown control contains a single numeric value that can be incremented or decremented by clicking the up or down buttons of the control. 用户还可以输入值,除非 ReadOnly 属性设置为 trueThe user can also enter in a value, unless the ReadOnly property is set to true.

可以通过设置 "DecimalPlaces"、"Hexadecimal" 或 "ThousandsSeparator" 属性来设置数值显示的格式。The numeric display can be formatted by setting the DecimalPlaces, Hexadecimal, or ThousandsSeparator properties. 若要在控件中显示十六进制值,请将 Hexadecimal 属性设置为 trueTo display hexadecimal values in the control, set the Hexadecimal property to true. 若要在适当的时候显示十进制数字中的千位分隔符,请将 ThousandsSeparator 属性设置为 trueTo display a thousands separator in decimal numbers when appropriate, set the ThousandsSeparator property to true. 若要指定在小数点符号后显示的位数,请将 DecimalPlaces 属性设置为要显示的小数位数。To specify the number of digits displayed after the decimal symbol, set the DecimalPlaces property to the number of decimal places to display.

若要为控件指定允许的值范围,请设置 "Minimum" 和 "Maximum" 属性。To specify the allowable range of values for the control, set the Minimum and Maximum properties. 设置 Increment 值,以指定当用户单击向上或向下箭头按钮时要递增或递减到 Value 属性的值。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. 当用户通过设置 "Accelerations" 属性连续按向上或向下箭头时,可以提高控件在数字间移动的速度。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.

当调用 UpButtonDownButton 方法(在代码中或通过单击向上或向下按钮)时,将验证新值并使用适当格式的新值更新控件。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. 具体而言,如果 UserEdit 属性设置为 true,则在验证或更新值之前调用 ParseEditText 方法。Specifically, if the UserEdit property is set to true, the ParseEditText method is called prior to validating or updating the value. 然后,将值验证为介于 MinimumMaximum 值之间,并调用 UpdateEditText 方法。The value is then verified to be between the Minimum and Maximum values, and the UpdateEditText method is called.

从 .NET Framework 4.6 开始,当 app.config 文件包含以下项时,将根据系统 DPI 设置调整 NumericUpDown 控件的大小: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>
