C# BitConverter ToString(Byte[], Int32, Int32)

Description

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

public static string ToString(
  byte[] value,//  ww  w.  ja  v a2 s  . c om
  int startIndex,
  int length
)

Parameters

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

• value - An array of bytes.
• startIndex - The starting position within value.
• length - The number of array elements in value to convert.

Returns

BitConverter.ToString(Byte[], Int32, 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 example uses the ToString method to convert part of a byte array, starting at the specified startIndex and with the specified length, to a string.

using System;//from  w  w  w  .j  a va 2 s  .  c  o  m

class BytesToStringDemo
{


    public static void Main( )
    {
        byte[ ] bytes = {
            170, 170, 170, 170, 170,   0,   0, 232, 137,   4, 
             35, 199, 138, 255, 232, 244, 255, 252, 205, 255, 
            255, 129 };

        Console.WriteLine(BitConverter.ToString( bytes, 2, 5 ) );
    }
}

The code above generates the following result.
