C# 比较两个 byte[] 的相等性

program:

 [DllImport("msvcrt.dll", CallingConvention = CallingConvention.Cdecl)]
        static extern int memcmp(byte[] b1, byte[] b2, long count);

        /// 

        /// 比较数组
        /// 
        /// 
        /// 
        /// 
        static bool ByteArrayCompare(byte[] b1, byte[] b2)
        {
            return b1.Length == b2.Length && memcmp(b1, b2, b1.Length) == 0;
        }

        static void Main(string[] args)
        {
            
            string str = "czj";
            string str1 = "jzc";
            byte[] b1 = System.Text.Encoding.Default.GetBytes(str);
            byte[] b2 = System.Text.Encoding.Default.GetBytes(str);
            byte[] b3 = System.Text.Encoding.Default.GetBytes(str1);

            //一
            {
                Console.WriteLine(ByteArrayCompare(b1, b2));//true
                Console.WriteLine(ByteArrayCompare(b1, b3));//false
            }
            //二
            {
                Console.WriteLine(b1.SequenceEqual(b2));//true
                Console.WriteLine(b1.SequenceEqual(b3));//false
            }

            Console.ReadKey();
        }

output:
