读取 hex 文件，转换为字符串并加载到 listBox答案

【问题标题】：Read hex file, convert to string and load to listBox读取 hex 文件，转换为字符串并加载到 listBox
【发布时间】：2012-05-09 15:18:03
【问题描述】：

我希望 listBox 显示存储在文件中的 ID。 ID 为十六进制值。

我一直在尝试加载文件并将 HEX 转换为 ASCII，因此 listBox 可以加载它。该文件还包含更多信息，如项目名称、项目级别等......

这是一个文件示例：

忽略开头的“50 12 00 00 2F D9 01 00”，即文件版本和其他不相关的数据，我要解析到listBox的是版本之后的项目ID“01”文件。

下一个项目 ID 为“00000330h”，值为“02”。在文件末尾，您可以看到 ID 为“03”...

编辑：

好的，现在我正在加载文件并读取其中的项目部分，但我不知道如何将 ID 加载到列表框中... ID 之间的间隔为 807 个字节，因此每 807 个字节就有一个 ID。

这是我加载文件部分的方式

    int itemSectionStart = 0x00000000;
    int itemSectionEnd = 0x002e11e0;

    FileStream fstream = new FileStream("C:\\Users\\xxx\\Desktop\\xxx\\xxx\\xxx.dec", FileMode.Open);
    BinaryReader breader = new BinaryReader(fstream);
    long length = fstream.Length;

    breader.BaseStream.Position = itemSectionStart;
    byte[] itemSection = breader.ReadBytes(itemSectionEnd);

【问题讨论】：

这让我想起了 PC 保存游戏文件和拥有大量积分的 ELITE :)
哈哈，是这样的：P
不明白为什么要 hex 到 ascii 的转换？这个十六进制转储只是一些十六进制查看器中文件的视觉呈现吗？
当我按下“加载”按钮时，listBox 必须加载所有项目 ID。 ID 采用 HEX 值，我希望这些值采用可读的 ASCII 格式。当它到达项目 ID“061A85”时，它将显示“400005”而不是 HEX 值。编辑：转储取自 UltraEdit 的文件视图
如果您发布的十六进制是准确的，那么您的 ID 实际上是由 808 个字节分隔的，无论如何这更有意义。我的回答应该适用于您想要做的事情（用相关表达式填写“NeedToByteSwap”和“AddToListView”等位）。如果有什么你不明白的，我可以试着为你澄清。

【解决方案1】：

假设您知道如何在文件中找到所需的 ID，并且知道它们的宽度（例如，您知道它们是每个 4 个字节组成一个 Int32），您可以使用 C# 的 BitConverter 类，它需要一个字节数组和索引，并返回相应的数字类型。如果字节序是一个问题，您可能需要交换一些东西。

将您的文件读入字节数组，在您关心的每个偏移处使用 BitConverter，将数字转换为字符串，然后加载您的 ListView。

int startIndex = 8;
int recordStride = 128;
int numRecords = 4;

using (FileStream str = File.OpenRead("myfile.ext")) {
    for (int i = 0; i < numRecords; i++) {
        byte[] data = new byte[4];
        str.Seek(startIndex + recordStride * i, SeekOrigin.Begin);
        str.Read(data, 0, 4);
        if (NeedToByteSwap)
            Array.Reverse(data);

        int id = BitConverter.ToInt32(data, 0);
        AddToListView(id.ToString());
    }
}

根据需要填写或计算您的起始参数。

终于完成了我想要的！这是我使它工作的方法：（可能不漂亮，但它有效！）

private string hex2dec(string hexString)
{
    StringBuilder sb = new StringBuilder();
    sb.Append(long.Parse(hexString, System.Globalization.NumberStyles.HexNumber));
    return sb.ToString();
}

private void button1_Click(object sender, EventArgs e)
{
    int numRecords = 3737;
    int itemSectionStart = 0x00000008;
    int itemSectionEnd = 0x002e11ec;

    using (FileStream str = File.OpenRead("C:\\Users\\xxx\\Desktop\\xxx\\xxx\\xxx.dec"))
    {
        BinaryReader breader = new BinaryReader(str);
        breader.BaseStream.Position = itemSectionStart;
        byte[] itemSection = breader.ReadBytes(itemSectionEnd);

        int j = 0;
        int k = j++;
        for (int i = 0; i < numRecords; i++)
        {
            string id = BitConverter.ToString(itemSection, 808 * k++, 7);
            string[] strArrayID = id.Split(new char[] { '-' });
            string reversedID = strArrayID[6] + strArrayID[5] + strArrayID[4] + strArrayID[3] + strArrayID[2] + strArrayID[1] + strArrayID[0];
            listBox1.Items.Add(this.hex2dec(reversedID));
        }
    }
}

【讨论】：

我不确定我是否理解您将其视为十六进制字符串的固定。您打算在其他地方使用十六进制字符串吗？为方便起见，您的文本编辑器以十六进制显示您的数据，但底层 id 数据与十六进制或 ASCII 无关。如果您的代码可以正常工作，那就太好了，但我认为您所做的工作比您真正需要做的要多得多。
如果它没有坏，就不要修理它，它对我来说很好用。

【解决方案3】：

听起来不像是十六进制格式的数据——听起来更像是编辑器给你的表示。相反，该文件似乎更有可能是一个直接的二进制转储，其文本编码为 ASCII 字节流。

在这种情况下，您希望隔离代表字符的 byte[] 范围（是否有明确的定义来分隔记录、名称等？）。喂它 System.Text.ASCIIEncoding (http://msdn.microsoft.com/en-us/library/system.text.asciiencoding.aspx)

GetString 重载之一会将字节范围转换为 ASCII 文本。 (http://msdn.microsoft.com/en-us/library/744y86tc.aspx)

【讨论】：

ID 相距 807 个字节，中间还有关于每个项目的其他数据。这些值是十六进制的，但它们是“反转的”，因此文件将显示“32 DF 14 3C”反转的十六进制值，实际上是“3C 14 DF 32”，并将转换为十进制形式的“1008000818”。跨度>
