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......

这是该文件的示例：

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，我要解析到列表框中的是文件版本之后的项目ID“01”。

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：

OK, now I am loading the file and reading the Item's section inside of it, but I have no clue how to load the IDs into the listBox... The IDs are separated from each other by 807 bytes, so every 807 bytes there is an ID.

Here is how I am loading the file's section

    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);

Assuming you know how to locate the IDs you want in the file, and you know their width (e.g. you know they're each 4 bytes comprising an Int32), you can use C#'s BitConverter class, which takes a byte array and an index and gives you back the corresponding numeric type. You may have to swap things around if endianness is an issue.

Read your file into a byte array, use BitConverter at each offset you care about, convert the numbers to strings, and load up your 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());
    }
}

Fill in or calculate your starting parameters as needed.

Finally accomplished what I was looking for! Here is the approach I took to make it work: (Might not be pretty, but it works!)

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));
        }
    }
}

Doesn't sound so much like the data is in Hex format - sounds more like that's just the representation that the editor gave you. Instead it seems more probably that the file is a straight binary dump with text encoded as ASCII byte stream.

In which case you'd want to isolate a byte[] range that represents the chars (is there a clear definition of what delimits records, names etc?). Feed that to System.Text.ASCIIEncoding (http://msdn.microsoft.com/en-us/library/system.text.asciiencoding.aspx)

One of the GetString overloads will convert the byte range to ASCII text. (http://msdn.microsoft.com/en-us/library/744y86tc.aspx)
