static void Main(string[] args)
{
CRC16_Test testbench = new CRC16_Test();
Console.WriteLine("Input A Array:");
string str = Console.ReadLine();
byte[] data1 = System.Text.Encoding.ASCII.GetBytes(str);
Console.WriteLine("Your Array is:{0}", data1);
testbench.MyCRC16_test(data1);
Console.WriteLine("Output CRC:{0}", testbench.MyCRC16_test(data1));
Console.ReadLine();
}
输入7E0005603131
输出结果:Your Array is:System.Byte[]
Output CRC:System.Byte[]
一定是我的方式不对,怎样才能看到数组里头的数据。求助~~~~~~~~~~谢谢!!1 |
