將字節值的字符串數組轉換為字節數組

Question

我在表單上有一個文本框，其中一個人以下面顯示的格式輸入字節數組。

我的問題是如何將生成的字符串數組轉換為相同值的字節數組？

因此這將被輸入到文本框中：

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

下面的代碼然后將其拆分並將其轉換為字節數組

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() ;
        }

並顯示它不起作用的響應

 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

只需清楚一點，0x11應該以字節11而不是字節17的形式返回，與所有其他我不想轉換為十進制的其他字符一樣，我試圖將文字字節的字符串轉換為字節數組以進行檢查-總和創造

Answer 1

您得到的字節只是字節； 它們本質上不是十進制或十六進制。

如果您想將字節傳遞給其他對象（用於校驗和），則可以。

唯一的問題是您將它們以十進制形式寫入控制台-如果您出於任何原因希望以十六進制形式寫入它們，請使用ToString("x") 。

Answer 2

請執行以下操作：

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);
        }

在這里，abc是所需的字節數組。 現在，用abc做任何您想做的事情。

您的代碼正在運行。 檢查一下以觀察不同的轉換並選擇您需要的任何東西：

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 }));
