将字节值的字符串数组转换为字节数组

Question

我在表单上有一个文本框，其中一个人以下面显示的格式输入字节数组。

我的问题是如何将生成的字符串数组转换为相同值的字节数组？

因此这将被输入到文本框中：

0x11, 0x01, 0x49, 0x4D, 0x41, 0x47, 0x45, 0x31, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, 0x53, 0x75, 0x6D, 0x6D, 0x61, 0x72, 0x79, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00

下面的代码然后将其拆分并将其转换为字节数组

string text = txtChecksumText.Text;
        string[] parts = text.Split(new string[] { ", " }, StringSplitOptions.None);
        byte[] bytes = new byte[parts.Length];

        for (int i = 0; i < parts.Length; i++)
        {
            bytes[i] = Convert.ToByte(parts[i], 16); // this isn't working as expected
            txtResponse.Text += Environment.NewLine + "     " + i + " = " + parts[i] + " = " + bytes[i].ToString() ;
        }

并显示它不起作用的响应

 0 = 0x11 = 17
 1 = 0x01 = 1
 2 = 0x49 = 73
 3 = 0x4D = 77
 4 = 0x41 = 65
 5 = 0x47 = 71
 6 = 0x45 = 69
 7 = 0x31 = 49
 8 = 0x00 = 0
 9 = 0x00 = 0
 10 = 0x00 = 0
 11 = 0x00 = 0
 12 = 0x00 = 0
 13 = 0x00 = 0
 14 = 0x00 = 0
 15 = 0x00 = 0
 16 = 0x00 = 0
 17 = 0x00 = 0
 18 = 0x00 = 0
 19 = 0x00 = 0
 20 = 0x00 = 0
 21 = 0x00 = 0
 22 = 0x00 = 0
 23 = 0x01 = 1
 24 = 0x53 = 83
 25 = 0x75 = 117
 26 = 0x6D = 109
 27 = 0x6D = 109
 28 = 0x61 = 97
 29 = 0x72 = 114
 30 = 0x79 = 121
 31 = 0x00 = 0
 32 = 0x00 = 0
 33 = 0x00 = 0
 34 = 0x00 = 0
 35 = 0x00 = 0
 36 = 0x00 = 0
 37 = 0x00 = 0
 38 = 0x00 = 0
 39 = 0x00 = 0
 40 = 0x00 = 0
 41 = 0x00 = 0
 42 = 0x00 = 0
 43 = 0x00 = 0
 44 = 0x00 = 0
 45 = 0x00 = 0
 46 = 0x00 = 0
 47 = 0x00 = 0
 48 = 0x00 = 0
 49 = 0x00 = 0
 50 = 0x00 = 0
 51 = 0x00 = 0
 52 = 0x00 = 0
 53 = 0x00 = 0
 54 = 0x00 = 0
 55 = 0x00 = 0

只需清楚一点，0x11应该以字节11而不是字节17的形式返回，与所有其他我不想转换为十进制的其他字符一样，我试图将文字字节的字符串转换为字节数组以进行检查-总和创造

Answer 1

您得到的字节只是字节； 它们本质上不是十进制或十六进制。

如果您想将字节传递给其他对象（用于校验和），则可以。

唯一的问题是您将它们以十进制形式写入控制台-如果您出于任何原因希望以十六进制形式写入它们，请使用ToString("x") 。

请执行以下操作：

txtHexString.Text="0x11, 0x01, 0x49, 0x4D, 0x41, 0x47, 0x45, 0x31, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, 0x53, 0x75, 0x6D, 0x6D, 0x61, 0x72, 0x79, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00";

string[] namesArray =  txtHexString.Text.Split(',');
byte[] abc= new byte [namesArray.Length];

for (int i = 0; i <= namesArray.Length - 1; i = i + 1)
        {
            abc[i] = Convert.ToByte(namesArray[i].Replace(" ", ""), 16);
        }

在这里，abc是所需的字节数组。 现在，用abc做任何您想做的事情。

您的代码正在运行。 检查一下以观察不同的转换并选择您需要的任何东西：

MessageBox.Show(11.ToString());
MessageBox.Show(11.ToString("x"));
MessageBox.Show(0x11.ToString());
MessageBox.Show(0x11.ToString("x"));
MessageBox.Show(BitConverter.ToString(new byte[] { 11, 0x11, 16 }));
