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)

Syntax

'Declaration
<SecuritySafeCriticalAttribute> _
Public Shared Function ToString ( _
    value As Byte, _
    toBase As Integer _
) As String

[SecuritySafeCriticalAttribute]
public static string ToString(
    byte value,
    int toBase
)

Parameters

  • 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.

Exceptions

Exception Condition
ArgumentException

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

Examples

The following code example converts several Byte values to String s with the ToString method in the radixes supported by the method.

Module Example

   Sub RunToStringDemo(ByVal outputBlock As System.Windows.Controls.TextBlock)

      Dim values As Byte() = { _
          Byte.MinValue, _
          13, _
          Byte.MaxValue}
      Dim radices As Integer() = {2, 8, 10, 16}

      ' Iterate through the values array.
      Dim value As Byte
      For Each value In values

         ' Iterate through the radices.
         Dim radix As Integer
         For Each radix In radices

            ' Convert a value with a radix.
            Dim valueString As String = _
                Convert.ToString(value, radix)

            outputBlock.Text &= String.Format("{0,7}  {1,3}    {2}", _
                value, radix, valueString) & vbCrLf
