C#中的Random.NextBytes()方法用于用随机数填充指定字节数组的元素。
语法如下-
public virtual void NextBytes (byte[] buffer);
缓冲区上方是字节数组。
现在让我们看一个例子-
using System; public class Demo { public static void Main(){ Random r = new Random(); Random r2 = new Random(); Random r3 = new Random(); Byte[] arr = new Byte[5]; r3.NextBytes(arr); Console.WriteLine("Random numbers....."); for (int i = 1; i <= 5; i++) Console.WriteLine(r.Next()); Console.WriteLine("\nRandom numbers from 1 to 10....."); for (int i = 1; i <= 5; i++) Console.WriteLine(r2.Next(10)); Console.WriteLine("\nRandom numbers in the byte array..."); for (int i = 0; i < arr.GetUpperBound(0); i++) Console.WriteLine(arr[i]); } }
输出结果
这将产生以下输出-
Random numbers..... 2081486546 329484380 1639318640 1499756340 2122408387 Random numbers from 1 to 10..... 9 1 7 6 9 Random numbers in the byte array... 210 92 112 52
现在让我们来看另一个示例-
using System; public class Demo { public static void Main(){ Random r = new Random(); Byte[] arr = new Byte[2]; r.NextBytes(arr); Console.WriteLine("Random numbers in the byte array..."); for (int i = 0; i < 2; i++) Console.WriteLine(arr[i]); } }
输出结果
这将产生以下输出-
Random numbers in the byte array... 173 11
