Description

BitConverter ToString(Byte[], Int32) converts the numeric value of each element of a specified subarray of bytes to its equivalent hexadecimal string representation.

Syntax

BitConverter.ToString(Byte[], Int32) has the following syntax.

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

Parameters

BitConverter.ToString(Byte[], Int32) has the following parameters.

• value - An array of bytes.
• startIndex - The starting position within value.

Returns

BitConverter.ToString(Byte[], Int32) method returns 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-00".

Example

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

using System;//from  ww w  .j a  v  a2s.c  o m

class BytesToStringDemo
{
    public static void Main( )
    {

        byte[ ] bytes = {
              0, 222,   0,   0,   0, 224, 111,  64,   0,   0, 
            224, 255, 255, 255, 239,  65,   0,   0, 131,   0,
