如何在C＃中将byte []分配为指针

using System;

public class Program
{
    public static void Main()
    {
        byte[] byteArray = new byte[] { 1, 2, 3, 4, 5 };
        unsafe
        {
            fixed (byte* ptr = byteArray)
            {
                Console.WriteLine("The first element of the byte array is: " + *ptr);
            }
        }
    }
}
