BitConverter.ToString Method (Byte(), Int32)

Converts the numeric value of each element of a specified subarray of bytes to its equivalent hexadecimal string representation.

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

'Declaration
Public Shared Function ToString ( _
	value As Byte(), _
	startIndex As Integer _
) As String

Parameters

value
Type: System.Byte()
An array of bytes.
startIndex
Type: System.Int32
The starting position within value.

Return Value

Type: System.String
A String of hexadecimal pairs separated by hyphens, where each pair represents the corresponding element in a subarray of value; for example, "7F-2C-4A".

ExceptionCondition
ArgumentNullException

value is Nothing.

ArgumentOutOfRangeException

startIndex is less than zero or greater than the length of value minus 1.

The elements from array position startIndex to the end of the array are converted.

The following code example converts the part of a Byte array starting at the specified startIndex to a String with the ToString method.


Module Example
   ' Display a Byte array, using multiple lines if necessary.
   Sub WriteMultiLineByteArray(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal bytes() As Byte, ByVal name As String)

      Const rowSize As Integer = 20
      Const underLine As String = "--------------------------------"
      Dim iter As Integer

      outputBlock.Text &= name & vbCrLf
      outputBlock.Text &= underLine.Substring(0, _
                  Math.Min(name.Length, underLine.Length)) & vbCrLf

      For iter = 0 To bytes.Length - rowSize - 1 Step rowSize
         outputBlock.Text &= BitConverter.ToString(bytes, iter, rowSize)
         outputBlock.Text &= "-" & vbCrLf
      Next iter

      outputBlock.Text &= BitConverter.ToString(bytes, iter) & vbCrLf
      outputBlock.Text &= vbCrLf
   End Sub
