July 28, 2014

Converts the value of the current Byte object to its equivalent string representation using the specified format and culture-specific formatting information.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public string ToString(
	string format,
	IFormatProvider provider
)

Parameters

format
Type: System.String
A standard or custom numeric format string.
provider
Type: System.IFormatProvider
An IFormatProvider object that supplies culture-specific formatting information.

Return Value

Type: System.String
The string representation of the current Byte object, formatted as specified by the format and provider parameters.

Implements

IFormattable.ToString(String, IFormatProvider)

ExceptionCondition
FormatException

format includes an unsupported specifier. Supported format specifiers are listed in the Remarks section.

The format parameter can be either a standard or a custom numeric format string. All standard numeric format strings other than "R" (or "r") are supported, as are all custom numeric format characters. If format is null or an empty string (""), the return value of this method is formatted with the general numeric format specifier ("G").

The provider parameter is an object that implements the IFormatProvider interface. Its GetFormat method returns a NumberFormatInfo object that provides culture-specific information about the format of the string that is returned by this method. The object that implements IFormatProvider can be any of the following:

  • A CultureInfo object that represents the culture whose formatting rules are to be used.

  • A NumberFormatInfo object that contains specific numeric formatting information for this value.

  • A custom object that implements IFormatProvider.

If provider is null or a NumberFormatInfo object cannot be obtained from provider, the return value is formatted using the NumberFormatInfo object for the thread current culture. For information about the thread current culture, see Thread.CurrentCulture.

The following example uses the standard "N" format string and four different CultureInfo objects to display the string representation of a byte value to the console.


byte byteValue = 250;
CultureInfo[] providers = {new CultureInfo("en-us"), 
                           new CultureInfo("fr-fr"), 
                           new CultureInfo("es-es"), 
                           new CultureInfo("de-de")};

foreach (CultureInfo provider in providers)
   outputBlock.Text += String.Format("{0} ({1})",
                     byteValue.ToString("N2", provider), provider.Name) + "\n";
// The example displays the following output:
//       250.00 (en-US)
//       250,00 (fr-FR)
//       250,00 (es-ES)
//       250,00 (de-DE)
