Question

我希望listBox显示存储在文件中的ID。 ID是十六进制值。

我试图加载文件并将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......

以下是该文件的示例：

00000000h: 50 12 00 00 2F D9 01 00 01 00 00 00 00 00 00 00 ; P.../Ù..........

在开始时忽略“50 12 00 00 2F D9 01 00”，即文件版本和其他无关数据，我想要解析到listBox的是项目ID“01”，它正好在版本之后文件。

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

修改

好的，现在我正在加载文件并阅读其中的Item部分，但我不知道如何将ID加载到listBox中... 这些ID彼此分开807个字节，因此每807个字节就有一个ID。

以下是我如何加载文件的部分

    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);

Answer 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，您知道它们每个包含一个Int32的4个字节），您可以使用C＃的BitConverter类，一个字节数组和一个索引，并返回相应的数字类型。如果字节序是一个问题，你可能不得不交换东西。

将文件读入字节数组，在您关注的每个偏移处使用BitConverter，将数字转换为字符串，然后加载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。

Answer 2

终于完成了我想要的东西！以下是我采用的方法:(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));
        }
    }
}

Answer 3

听起来不像十六进制格式的数据 - 听起来更像是编辑给你的表现。相反，似乎更可能的是该文件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，你想要隔离一个表示字符的byte []范围（是否有明确定义记录，名称等的界限？）。喂那个 System.Text.ASCIIEncoding（http://msdn.microsoft.com/en-us/library/system.text.asciiencoding.aspx）

其中一个GetString重载会将字节范围转换为ASCII文本。（http://msdn.microsoft.com/en-us/library/744y86tc.aspx）

读取hex文件，转换为string并加载到listBox
