This class defines how numbers are displayed according to culture and language. Formats for currency and its symbols and types of numeric formats, such as scientific and hexadecimal notations and their separators, are described by the properties of this class. As with DateTimeFormatInfo , a set of standard numeric formats is predefined and specified by format characters . The default property values apply to the invariant culture settings. The culture-specific NumberFormatInfo instance is retrieved by CurrentInfo , which is determined by the CultureInfo of the current thread or environment. public sealed class NumberFormatInfo : ICloneable, IFormatProvider { // Public Constructors public NumberFormatInfo ( ); // Public Static Properties public static NumberFormatInfo CurrentInfo {get; } public static NumberFormatInfo InvariantInfo {get; } // Public Instance Properties public int CurrencyDecimalDigits {set; get; } public string CurrencyDecimalSeparator {set; get; } public string CurrencyGroupSeparator {set; get; } public int[ ] CurrencyGroupSizes {set; get; } public int CurrencyNegativePattern {set; get; } public int CurrencyPositivePattern {set; get; } public string CurrencySymbol {set; get; } public bool IsReadOnly {get; } public string NaNSymbol {set; get; } public string NegativeInfinitySymbol {set; get; } public string NegativeSign {set; get; } public int NumberDecimalDigits {set; get; } public string NumberDecimalSeparator {set; get; } public string NumberGroupSeparator {set; get; } public int[ ] NumberGroupSizes {set; get; } public int NumberNegativePattern {set; get; } public int PercentDecimalDigits {set; get; } public string PercentDecimalSeparator {set; get; } public string PercentGroupSeparator {set; get; } public int[ ] PercentGroupSizes {set; get; } public int PercentNegativePattern {set; get; } public int PercentPositivePattern {set; get; } public string PercentSymbol {set; get; } public string PerMilleSymbol {set; get; } public string PositiveInfinitySymbol {set; get; } public string PositiveSign {set; get; } // Public Static Methods public static NumberFormatInfo GetInstance (IFormatProvider formatProvider ); public static NumberFormatInfo ReadOnly (NumberFormatInfo nfi ); // Public Instance Methods public object Clone ( ); // implements ICloneable public object GetFormat (Type formatType ); // implements IFormatProvider } Returned ByCultureInfo.NumberFormat Passed ToCultureInfo.NumberFormat |
