它将字节从一个字节数组复制到另一字节数组。
using System; class Demo { static void Main() { //字节数组 byte[] b1 = new byte[] {55, 66, 77, 88, 99}; byte[] b2 = new byte[8]; //将字节从一个复制到另一个 Buffer.BlockCopy(b1, 0, b2, 0, 5); /* 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(); } }
