Buffer Type in C#

To handle range of bytes, use Buffer Type in C#. Its method Buffer.BlockCopy copies the bytes from one byte array to another byte array.

Example

using System;
class Demo {
   static void Main() {
      // byte arrays
      byte[] b1 = new byte[] {39, 45, 58 };
      byte[] b2 = new byte[5];
      // copying bytes from one to another
      Buffer.BlockCopy(b1, 0, b2, 0, 3);
      /* 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();
   }
}
