Examples

The following example iterates an array of byte values and displays each of them to the console by calling the ToString(IFormatProvider) method with different format providers.

array<Byte>^ bytes = gcnew array<Byte> {0, 1, 14, 168, 255};
array<CultureInfo^>^ providers = {gcnew CultureInfo("en-us"), 
                                  gcnew CultureInfo("fr-fr"), 
                                  gcnew CultureInfo("de-de"), 
                                  gcnew CultureInfo("es-es")};
for each (Byte byteValue in bytes)
{
   for each (CultureInfo^ provider in providers)
      Console::Write("{0,3} ({1})      ", 
                    byteValue.ToString(provider), provider->Name);

Remarks

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

Remarks

The ToString(String, IFormatProvider) method formats a Byte value in a specified format of a specified culture. To format a number by using the default ("G") format of the current culture, call the ToString() method. To format a number by using a specified format of the current culture, call the ToString(String) method.

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

See also

ToString(String)

Converts the value of the current Byte object to its equivalent string representation using the specified format.

public:
 System::String ^ ToString(System::String ^ format);
public string ToString (string format);
override this.ToString : string -> string
Public Function ToString (format As String) As String

Parameters

format
String

A numeric format string.

The string representation of the current Byte object, formatted as specified by the format parameter.

Exceptions

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

Examples

The following example initializes a Byte value and displays it to the console using each of the supported standard format strings and a custom format string. The example is run with en-US as the current culture.

array<String^>^ formats = gcnew array<String^> {"C3", "D4", "e1", "E2", "F1", "G", "N1", 
                                                "P0", "X4", "0000.0000"};
Byte number = 240;
for each (String^ format in formats)
   Console::WriteLine("'{0}' format specifier: {1}", 
                     format, number.ToString(format));

// The example displays the following output to the console if the
// current culture is en-us:

Remarks

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 is formatted with the general numeric format specifier ("G").

The return value of this function is formatted using the NumberFormatInfo object for the thread current culture. For information about the thread current culture, see Thread.CurrentCulture. To provide formatting information for cultures other than the current culture, call the Byte.ToString(String, IFormatProvider) method.

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

See also

ToString()

Converts the value of the current Byte object to its equivalent string representation.

public:
 override System::String ^ ToString();
public override string ToString ();
override this.ToString : unit -> string
Public Overrides Function ToString () As String

Returns

The string representation of the value of this object, which consists of a sequence of digits that range from 0 to 9 with no leading zeroes.

Examples

The following example displays an array of byte values. Note that the ToString() method is not called explicitly in the example. Instead, it is called implicitly, because of the use of the composite formatting feature.

array<Byte>^ bytes = gcnew array<Byte> {0, 1, 14, 168, 255};
for each (Byte byteValue in bytes)
   Console::WriteLine(byteValue);
// The example displays the following output to the console if the current
// culture is en-US:
//       0
//       1
//       14
//       168
//       255
byte[] bytes = {0, 1, 14, 168, 255};
foreach (byte byteValue in bytes)
   Console.WriteLine(byteValue);
// The example displays the following output to the console if the current
// culture is en-US:
//       0
//       1
//       14
//       168
//       255
Dim bytes() As Byte = {0, 1, 14, 168, 255}
For Each byteValue As Byte In Bytes
   Console.WriteLine(byteValue)
Next   
' The example displays the following output to the console if the current
' culture is en-US:
'       0
'       1
'       14
'       168
'       255      

Remarks

The return value is formatted with the general numeric format specifier ("G") and the NumberFormatInfo object for the thread current culture. To define the formatting of the Byte value's string representation, call the ToString method. To define both the format specifiers and culture used to create the string representation of a Byte value, call the ToString method.
