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

public string ToString(
	string format


Type: System.String
A numeric format string.

Return Value

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


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 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:

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.

string[] formats = {"C3", "D4", "e1", "E2", "F1", "G", "N1", 
                    "P0", "X4", "0000.0000"};
byte number = 240;
foreach (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:
//       'C3' format specifier: $240.000
//       'D4' format specifier: 0240
//       'e1' format specifier: 2.4e+002
//       'E2' format specifier: 2.40E+002
//       'F1' format specifier: 240.0
//       'G' format specifier: 240
//       'N1' format specifier: 240.0
//       'P0' format specifier: 24,000 %
//       'X4' format specifier: 00F0
//       '0000.0000' format specifier: 0240.0000
