Examples

The following example formats a 16-bit signed integer value by using several format providers, including one for the invariant culture. The output from the example illustrates that the formatted string returned by the ToString(IFormatProvider) method is the same regardless of the format provider.

using System;
using System.Globalization;

{
   public static void Main()
   {
      // Define an array of CultureInfo objects.
      CultureInfo[] ci = { new CultureInfo("en-US"),

Remarks

The ToString(IFormatProvider) method formats a UInt16 value in the default ("G", or general) format by using the NumberFormatInfo object of a specified culture. If you want to specify a different format or the current culture, 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()
A specific format	Default (current) culture	ToString(String)
A specific format	A specific culture	ToString(String, IFormatProvider)

The provider parameter is an IFormatProvider implementation. Its GetFormat method returns a NumberFormatInfo object that provides culture-specific formatting information. However, none of the properties of the NumberFormatInfo are used when formatting with the general numeric format specifier ("G").

Remarks

The ToString(String) method formats a UInt16 value in a specified format by using a NumberFormatInfo object that represents the conventions of the current culture. If you want to use the default ("G", or general) format or specify a different culture, 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	A specific culture	ToString(String, IFormatProvider)

The format parameter can be any valid standard numeric format specifier, or any combination of custom numeric format specifiers. If format is equal to String.Empty or is null, the return value of the current UInt16 object is formatted with the general format specifier ("G"). If format is any other value, the method throws a FormatException.

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

For more information about numeric format specifiers, see Standard Numeric Format Strings and Custom Numeric Format Strings.
For more information about support for formatting in .NET, see Formatting Types.

The format of the returned string is determined by the NumberFormatInfo object for the current culture. Depending on the format parameter, this object controls symbols such as the group separator and the decimal point symbol in the output string. To provide formatting information for cultures other than the current culture, call the ToString(String, IFormatProvider) overload.

Remarks

The ToString(String, IFormatProvider) method formats a UInt16 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 any valid Standard Numeric Format Strings, or any combination of Custom Numeric Format Strings. If format is equal to String.Empty or is null, the return value of the current UInt16 object is formatted with the general format specifier ("G"). If format is any other value, the method throws a FormatException.

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

For more information about numeric format specifiers, see Standard Numeric Format Strings and Custom Numeric Format Strings.
For more information about formatting, see Formatting Types.

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 returned by this method. When the ToString(String, IFormatProvider) method is invoked, it calls the provider parameter's IFormatProvider.GetFormat method and passes it a Type object that represents the NumberFormatInfo type. The GetFormat method then returns the NumberFormatInfo object that provides information for formatting the current UInt16 value, such as the group separator symbol or the decimal point symbol. There are three ways to use the provider parameter to supply formatting information to the ToString(String, IFormatProvider) method:

You can pass a CultureInfo object that represents the culture that supplies formatting information. Its GetFormat method returns the NumberFormatInfo object that provides numeric formatting information for that culture.
You can pass the actual NumberFormatInfo object that provides numeric formatting information. (Its implementation of GetFormat just returns itself.)
You can pass a custom object that implements IFormatProvider. Its GetFormat method instantiates and returns the NumberFormatInfo object that provides formatting information.

If provider is null, the formatting of the returned string is based on the NumberFormatInfo object of the current culture.

Examples

The following example displays a UInt16 value by using the default ToString() method. It also displays the string representations of the UInt16 value that results from using some standard format specifiers. The examples are displayed using the formatting conventions of the en-US culture.

using System;

public class Example
{
   public static void Main()
   {
      ushort value = 16324;
      // Display value using default ToString method.
      Console.WriteLine(value.ToString());      
      Console.WriteLine();
      
      // Define an array of format specifiers.
      string[] formats = { "G", "C", "D", "F", "N", "X" };
      // Display value using the standard format specifiers.
      foreach (string format in formats)
         Console.WriteLine("{0} format specifier: {1,12}", 
                           format, value.ToString(format));         
   }
}
// The example displays the following output:
//       16324
//
//       G format specifier:        16324
//       C format specifier:   $16,324.00
//       D format specifier:        16324
//       F format specifier:     16324.00
//       N format specifier:    16,324.00
//       X format specifier:         3FC4

let value = 16324us
// Display value using default ToString method.
printfn $"{value.ToString()}\n"     

// Define an array of format specifiers.
let formats = [| "G"; "C"; "D"; "F"; "N"; "X" |]
// Display value using the standard format specifiers.
for format in formats do
    printfn $"{format} format specifier: {value.ToString format,12}" 
// The example displays the following output:
//       16324
//
//       G format specifier:        16324
//       C format specifier:   $16,324.00

Module Example
   Public Sub Main()
      Dim value As UInt16 = 16324

      Dim formats() As String = { "G", "C", "D", "F", "N", "X" }
      ' Display value using the standard format specifiers.
      For Each format As String In formats
         Console.WriteLine("{0} format specifier: {1,12}", _
                           format, value.ToString(format))

Remarks

The ToString() method formats a UInt16 value in the default ("G", or general) format by using the NumberFormatInfo object of the current culture. If you want to specify a different format or culture, use the other overloads of the ToString method, as follows:

To use format	For culture	Use the overload
Default ("G") format	A specific culture	ToString(IFormatProvider)
A specific format	Default (current) culture	ToString(String)
A specific format	A specific culture	ToString(String, IFormatProvider)
