C# BitConverter.ToString(Byte[]) Method

The BitConverter.ToString() method in C# is used to convert the numeric value of each element of a specified array of bytes to its equivalent hexadecimal string representation.

Syntax

public static string ToString (byte[] val);

Above, val is the byte array.

Example

 Live Demo

using System;
public class Demo {
   public static void Main() {
      byte[] arr = {0, 10, 2, 5, 32, 45};
      int count = arr.Length;
      Console.Write("Byte Array... ");
      for (int i = 0; i < count; i++) {
         Console.Write("
"+arr[i]);
      }
      Console.WriteLine("
Byte Array (String representation) = {0} ",
      BitConverter.ToString(arr));
   }
}

Output

Byte Array...
0
10
2
5
32
45
Byte Array (String representation) = 00-0A-02-05-20-2D

Example

 Live Demo

using System;
public class Demo {
   public static void Main() {
      byte[] arr = { 0, 0, 7, 10, 18, 20, 25, 26, 32};
      int count = arr.Length;
      Console.Write("Byte Array... ");
      for (int i = 0; i < count; i++) {
         Console.Write("
"+arr[i]);
      }
      Console.WriteLine("
Byte Array (String representation) = "+BitConverter.ToString(arr));
      for (int i = 0; i < arr.Length - 1; i = i + 2) {
         short res = BitConverter.ToInt16(arr, i);
         Console.WriteLine("
Value = "+arr[i]);
         Console.WriteLine("Result = "+res);
      }
   }
}

Output

Byte Array...
0
0
7
10
18
20
25
26
32
Byte Array (String representation) = 00-00-07-0A-12-14-19-1A-20
Value = 0
Result = 0
Value = 7
Result = 2567
Value = 18
Result = 5138
Value = 25
Result = 6681
