让我发疯，数字转换 [英] Driving me insane, number conversion

问题描述

:mad:
亲爱的编码员，这个问题使我发疯.

我正在使用Visual Studio 2008，C#.net，Windows窗体...

我想在Windows窗体上有一个编辑/文本框，该框将接受如下所示的数字字符串:

456345-007876-343234-765676-543456-566565-321234-345654

然后在去除-"间隔符之后，我想将上面的内容表示为字节数组，这将是x字节编码，例如:

{0x56,0x33,0x56,0x66,0x77 ........}(示例)

然后，我可以处理上述字节数组，例如对其进行加密等.

然后，我想将新的字节数组转换回其数字字符串，因此在更改字节数组后，它现在可能会输出:

456544-676777-231234-567423-456776-567898-998788-455654

我发现了许多示例，这些示例允许我将代码编码/解码为十六进制或以64为基数或以32为基数，但是重要的是我可以用数字表示数据.

希望有人能帮助我吗?
提前非常感谢您
Steve

Dear Coders, this problem is driving me insane.

I am using Visual Studio 2008, C# .net, windows forms...

I want to have an edit/text box on my windows form that will accepts a string of digits like the following:

456345-007876-343234-765676-543456-566565-321234-345654

Then after stripping out the ''-'' spacers, i want to represent the above as a byte array, which would be an x byte encoding, something like:

{0x56,0x33,0x56,0x66,0x77........} (example)

I can then work on the above byte array, for example encrypt it etc.

Then i want to convert the new byte array back to its number string, so after altering the byte array, it might now output:

456544-676777-231234-567423-456776-567898-998788-455654

I have found many examples that allow me to encode/decode to hex or base 64 or base 32 etc, but it is important that i can represent my data with numbers.

Hope some on can please help me?
Thank you VERY much in advance
Steve

推荐答案

对我来说，这似乎是一项艰巨的任务.到目前为止你做了什么?您的特定问题是什么?
:)

It looks like a quite strightforward task to me. What have you done so far? What is your specific problem about?
:)

类似这样的事情??

Something like this...?

internal static string SerialToHex(string serial)
{
    serial = serial.Replace("-", string.Empty);
    int value;
    string result = string.Empty;
    for (int i = 0; i < serial.Length / 6; i++)
    {
        int.TryParse(serial.Substring(6 * i, 6), NumberStyles.None, CultureInfo.InvariantCulture, out value);
        result += value.ToString("X5", CultureInfo.InvariantCulture);
    }
    return result;
}

internal static byte[] HexToBytes(string hex)
{
    byte[] result = new byte[hex.Length / 2];
    for (int i = 0; i < hex.Length / 2; i++)
    {
        byte.TryParse(hex.Substring(2 * i, 2), NumberStyles.AllowHexSpecifier, CultureInfo.InvariantCulture, out result[i]);
    }
    return result;
}

internal static byte[] EncryptBytes(byte[] bytes)
{
    // TODO: Add your code here
    return bytes;
}

internal static string BytesToHex(byte[] bytes)
{
    string result = string.Empty;
    for (int i = 0; i < bytes.Length; i++)
    {
        result += bytes[i].ToString("X2", CultureInfo.InvariantCulture);
    }
    return result;
}

internal static string HexToSerial(string hex)
{
    string result = string.Empty;
    int value;
    for (int i = 0; i < hex.Length / 5; i++)
    {
        int.TryParse(hex.Substring(5 * i, 5), NumberStyles.AllowHexSpecifier, CultureInfo.InvariantCulture, out value);
        result += value.ToString("D6", CultureInfo.InvariantCulture);
        result += "-";
    }
    result = result.Remove(result.Length - 1);
    return result;
}

internal static bool Test(string serialIn)
{
    string hexIn = SerialToHex(serialIn);
    byte[] bytes = HexToBytes(hexIn);
    string hexOut = BytesToHex(bytes);
    string serialOut = HexToSerial(hexOut);
    return serialIn == serialOut;
}
