Int16.ToString Method (String, IFormatProvider)

Converts the numeric value of this instance 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 numeric format string.

provider
Type: System.IFormatProvider

An object that supplies culture-specific formatting information.

Return Value

Type: System.String
The string representation of the value of this instance as specified by format and provider.

Implements

IFormattable.ToString(String, IFormatProvider)

The ToString(String, IFormatProvider) method formats an Int16 value in a specified format by using the NumberFormatInfo object of a specified culture. If you want to use default format or culture settings, use the other overloads of the ToString method, as follows:

To use format

For culture

Use the overload

Default ("G") format

Default (current) culture

ToString()

Default ("G") format

A specific culture

ToString(IFormatProvider)

A specific format

Default (current) culture

ToString(String)

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 string returned by this method is formatted with the general numeric format specifier ("G").

The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics:

The provider parameter is an IFormatProvider implementation. 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 with the NumberFormatInfo for the current culture.

The following example displays an Int16 value using each of the supported standard format strings in four different cultures.

Int16 value = 14603;
string[] formats = {"C", "D6", "e1", "E2", "F1", "G", "N1", 
                    "P0", "X4", "000000.0000", "##000.0"};
CultureInfo[] providers = {new CultureInfo("en-us"), 
                           new CultureInfo("fr-fr"), 
                           new CultureInfo("de-de"), 
                           new CultureInfo("es-es")};
// Display header.
Console.WriteLine("{0,24}{1,14}{2,14}{3,14}", providers[0], providers[1], 
                  providers[2], providers[3]);
Console.WriteLine();
// Display a value using each format string. 
foreach (string format in formats)
{
   // Display the value for each provider on the same line.
   Console.Write("{0,-12}", format);
   foreach (CultureInfo provider in providers)
   {
      Console.Write("{0,12}  ", 
                    value.ToString(format, provider)); 
   }
   Console.WriteLine();
}
// The example displays the following output to the console:
