RangeValidator Currency value can't contain more than 2 digits after decimal?
提问by user1118064
Framework 4.0 Asp.net application
框架 4.0 Asp.net 应用程序
When I run the code I got a error "The value '999.9999' of the MaximumValue property of 'RangeValidator' cannot be converted to type 'Currency'.
当我运行代码时，出现错误“'RangeValidator'的MaximumValue属性的值'999.9999'无法转换为'Currency'类型。
Below is my code:
下面是我的代码：
<asp:RangeValidator Runat='server' ControlToValidate='textEdit'
MinimumValue='0.0001'
MaximumValue='999.9999' Type='Currency'
ErrorMessage='Should be between 0.0001 and 999.9999' id="idValidtor"
display='None' />
Please explain me is currency value can't contain more than 2 digits after decimal? Unless how can I resolve this issue?
请解释我是货币价值不能包含超过 2 位小数点后？除非我怎样才能解决这个问题？

The RangeValidatoruses the NumberFormatInfo.CurrencyDecimalDigitsproperty to determine if the string can be converted to a currency, otherwise it will throw your exception. From MSDN:
在RangeValidator使用NumberFormatInfo.CurrencyDecimalDigits属性来确定该字符串是否可以转换为货币，否则会抛出你的异常。从MSDN：
when a RangeValidator control's Type property is set to "Currency", the MinimumValue and MaximumValue properties must be provided in a format such as that described in NumberFormatInfo.CurrencyDecimalDigits, otherwise an exception is thrown.
当 RangeValidator 控件的 Type 属性设置为“Currency”时，必须以 NumberFormatInfo.CurrencyDecimalDigits 中描述的格式提供 MinimumValue 和 MaximumValue 属性，否则将引发异常。
The default for most cultures (incl. InvariantCulture) is 2 (arabic countries have 3 but none 4).
大多数文化（包括InvariantCulture）的默认值是 2（阿拉伯国家有 3 但没有 4）。
So what culture are you using? If it is important to store more decimal places than two in a currency, then you could use a custom NumberFormatInfoin this page:
那么你使用的是什么文化？如果在货币中存储多于两位的小数位很重要，那么您可以NumberFormatInfo在此页面中使用自定义：
protected void Page_PreInit(object sender, EventArgs e)
{
var customCulture = (CultureInfo)CultureInfo.CurrentCulture.Clone();
var nfi = (NumberFormatInfo)customCulture.NumberFormat.Clone();
nfi.CurrencyDecimalDigits = 4;
customCulture.NumberFormat = nfi;
System.Threading.Thread.CurrentThread.CurrentCulture = customCulture;
}
(note that you need to add using System.Globalization;at the top)
（注意需要using System.Globalization;在顶部添加）
