NumberFormatInfo.InvariantInfo Property

Gets a read-only NumberFormatInfo object that is culture-independent (invariant).

Namespace:  System.Globalization
Assemblies:   mscorlib (in mscorlib.dll)
  System.Globalization (in System.Globalization.dll)

public static NumberFormatInfo InvariantInfo { get; }

Property Value

Type: System.Globalization.NumberFormatInfo
A read-only object that is culture-independent (invariant).

This NumberFormatInfo object returned by this property does not change, regardless of the current culture. It represents the formatting conventions of the invariant culture, which is a culture associated with the English language but not with any country/region. The invariant culture is used in formatting operations that are culture-independent or that produce result strings suitable for display across multiple cultures.

The following example displays the default property values of the InvariantInfo.

using System;
using System.Globalization;
using System.Text;

class SamplesNumberFormatInfo  {

   public static void Main()  {

      // Gets the InvariantInfo.
      NumberFormatInfo myInv = NumberFormatInfo.InvariantInfo;

      // Gets a UnicodeEncoding to display the Unicode value of symbols.
      UnicodeEncoding myUE = new UnicodeEncoding( true, false );
      byte[] myCodes;

      // Displays the default values for each of the properties.
      Console.WriteLine( "InvariantInfo:\nNote: Symbols might not display correctly on the console,\ntherefore, Unicode values are included." );
      Console.WriteLine( "\tCurrencyDecimalDigits\t\t{0}", myInv.CurrencyDecimalDigits );
      Console.WriteLine( "\tCurrencyDecimalSeparator\t{0}", myInv.CurrencyDecimalSeparator );
      Console.WriteLine( "\tCurrencyGroupSeparator\t\t{0}", myInv.CurrencyGroupSeparator );
      Console.WriteLine( "\tCurrencyGroupSizes\t\t{0}", myInv.CurrencyGroupSizes[0] );
      Console.WriteLine( "\tCurrencyNegativePattern\t\t{0}", myInv.CurrencyNegativePattern );
      Console.WriteLine( "\tCurrencyPositivePattern\t\t{0}", myInv.CurrencyPositivePattern );
      myCodes = myUE.GetBytes( myInv.CurrencySymbol );
      Console.WriteLine( "\tCurrencySymbol\t\t\t{0}\t(U+{1:x2}{2:x2})", myInv.CurrencySymbol, myCodes[0], myCodes[1] );
      Console.WriteLine( "\tNaNSymbol\t\t\t{0}", myInv.NaNSymbol );
      Console.WriteLine( "\tNegativeInfinitySymbol\t\t{0}", myInv.NegativeInfinitySymbol );
      Console.WriteLine( "\tNegativeSign\t\t\t{0}", myInv.NegativeSign );
      Console.WriteLine( "\tNumberDecimalDigits\t\t{0}", myInv.NumberDecimalDigits );
      Console.WriteLine( "\tNumberDecimalSeparator\t\t{0}", myInv.NumberDecimalSeparator );
      Console.WriteLine( "\tNumberGroupSeparator\t\t{0}", myInv.NumberGroupSeparator );
      Console.WriteLine( "\tNumberGroupSizes\t\t{0}", myInv.NumberGroupSizes[0] );
      Console.WriteLine( "\tNumberNegativePattern\t\t{0}", myInv.NumberNegativePattern );
      Console.WriteLine( "\tPercentDecimalDigits\t\t{0}", myInv.PercentDecimalDigits );
      Console.WriteLine( "\tPercentDecimalSeparator\t\t{0}", myInv.PercentDecimalSeparator );
      Console.WriteLine( "\tPercentGroupSeparator\t\t{0}", myInv.PercentGroupSeparator );
      Console.WriteLine( "\tPercentGroupSizes\t\t{0}", myInv.PercentGroupSizes[0] );
      Console.WriteLine( "\tPercentNegativePattern\t\t{0}", myInv.PercentNegativePattern );
      Console.WriteLine( "\tPercentPositivePattern\t\t{0}", myInv.PercentPositivePattern );
      myCodes = myUE.GetBytes( myInv.PercentSymbol );
      Console.WriteLine( "\tPercentSymbol\t\t\t{0}\t(U+{1:x2}{2:x2})", myInv.PercentSymbol, myCodes[0], myCodes[1] );
      myCodes = myUE.GetBytes( myInv.PerMilleSymbol );
      Console.WriteLine( "\tPerMilleSymbol\t\t\t{0}\t(U+{1:x2}{2:x2})", myInv.PerMilleSymbol, myCodes[0], myCodes[1] );
      Console.WriteLine( "\tPositiveInfinitySymbol\t\t{0}", myInv.PositiveInfinitySymbol );
      Console.WriteLine( "\tPositiveSign\t\t\t{0}", myInv.PositiveSign );

   }
