C# program to copy a range of bytes from one array to another

CsharpProgrammingServer Side Programming

Use the Buffer.BlockCopy method to copy a range of bytes from one array to another −

Set a byte array −

byte[] b1 = new byte[] {22, 49};
byte[] b2 = new byte[5];

Copy bytes from one array to another −

Buffer.BlockCopy(b1, 0, b2, 0, 2);

The following is the complete code −

Example

 Live Demo

using System;
class Demo {
   static void Main(){
      // byte arrays
      byte[] b1 = new byte[] {22, 49};
      byte[] b2 = new byte[5];
      // copying bytes from one to another
      Buffer.BlockCopy(b1, 0, b2, 0, 2);
      /* calling the method with the byte array b2 that has the copied elements */
      bufferFunc(b2);
   }
   static void bufferFunc(byte[] a) {
      for (int j = 0; j < a.Length; j++) {
         Console.Write(a[j]);
      }
      Console.WriteLine();
   }
}
