Convert.ToString Method (Byte, Int32)

Converts the value of an 8-bit unsigned integer to its equivalent string representation in a specified base.

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

'Declaration
Public Shared Function ToString ( _
	value As Byte, _
	toBase As Integer _
) As String
'Usage
Dim value As Byte 
Dim toBase As Integer 
Dim returnValue As String 

returnValue = Convert.ToString(value, _
	toBase)

Parameters

value
Type: System.Byte

The 8-bit unsigned integer to convert.

toBase
Type: System.Int32

The base of the return value, which must be 2, 8, 10, or 16.

Return Value

Type: System.String
The string representation of value in base toBase.

ExceptionCondition
ArgumentException

toBase is not 2, 8, 10, or 16.

If toBase does not equal 10, the string that is returned by the Convert.ToString(Byte, Int32) method represents value by its magnitude only. If the method is called to create a string that will later be converted back to a number, a corresponding method that assumes a magnitude-only numeric representation should be called to perform the conversion. Such methods include Convert.ToByte(String, Int32) or Byte.Parse(String, NumberStyles).

The following example converts each element in a byte array to its equivalent binary, hexadecimal, decimal, and hexadecimal string representations.

Dim bases() As Integer = { 2, 8, 10, 16}
Dim numbers() As Byte = { Byte.MinValue, 12, 103, Byte.MaxValue}

For Each base As Integer In bases
   Console.WriteLine("Base {0} conversion:", base)
   For Each number As Byte In numbers
      Console.WriteLine("   {0,-5}  -->  0x{1}", _
                        number, Convert.ToString(number, base))
