写一个字符串格式的十六进制块，以二进制值注册

本文关键字：十六进制 二进制 注册 格式 字符串 一个 | 更新日期: 2023-09-27 18:17:52

我真的遇到麻烦了。我有一个字符串，其中包括十六进制值:

string creatatorsid =@"01,05年,00 00 00,00,00,05年,15日00,00,00,10,b1, 9 d, 4, 7, 85, 7 b, 05年,79, 05年b3 7 c, ee, 03年,00 00";

我想把它放到需要二进制值的registrykey中。

我试过了:

键。SetValue("creatorSID"， creatorSID, RegistryValueKind.Binary);

但是我得到错误信息，它不能被转换。

下面是到目前为止的完整代码:

class Program
{
    static void Main(string[] args)
    {
        String printerName = "Naked";
        RegistryKey key = Registry.LocalMachine.OpenSubKey(@"SYSTEM'CurrentControlSet'Control'Print'Printers'" + printerName , true);

        string security = "01,00,0c,80,d0,00,00,00,dc,00,00,00,00,00,00,00,14,00,00,00,02," +
                           "00,bc,00,07,00,00,00,00,00,24,00,0c,00,0f,00,01,05,00,00,00,00,00,05,15,00," +
                            "00,00,10,b1,9d,4a,7a,85,7b,05,79,05,b3,7c,ee,03,00,00,00,09,24,00,30,00,0f," +
                            "00,01,05,00,00,00,00,00,05,15,00,00,00,10,b1,9d,4a,7a,85,7b,05,79,05,b3,7c," +
                            "ee,03,00,00,00,09,14,00,00,00,00,10,01,01,00,00,00,00,00,03,00,00,00,00,00," +
                            "00,14,00,08,00,02,00,01,01,00,00,00,00,00,01,00,00,00,00,00,0a,14,00,00,00," +
                            "00,20,01,01,00,00,00,00,00,01,00,00,00,00,00,00,18,00,0c,00,0f,00,01,02,00," +
                            "00,00,00,00,05,20,00,00,00,20,02,00,00,00,0b,18,00,00,00,00,10,01,02,00,00," +
                            "00,00,00,05,20,00,00,00,20,02,00,00,01,01,00,00,00,00,00,05,12,00,00,00,01," +
                            "01,00,00,00,00,00,05,12,00,00,00";

        var data = Encoding.Unicode.GetBytes(security);
        try
        {
             key.SetValue("Security", data, RegistryValueKind.Binary);
        }
        catch (Exception exc)
        {
            Console.WriteLine(exc.Message);
            Console.WriteLine(exc.StackTrace);
        }

    }
}

现在正在写入条目，但是值发生了变化。如果我检查键有:"30 00 31 00 ....."在它。但它一定是:"01 000 c 80....."(必须是字符串中的值)

写一个字符串格式的十六进制块，以二进制值注册

当您使用string时，您必须使用RegistryValueKind.String。

key.SetValue("creatorSID", creatorSid , RegistryValueKind.String);

如果您需要使用RegistryValueKind.Binary，则需要将string转换为byte[]并将其存储为byte[]。

存储值:

var data = Encoding.Unicode.GetBytes(creatorSid);
key.SetValue("creatorSID", data, RegistryValueKind.Binary);

返回值:

var data = (byte[])key.GetValue("creatorSID");
if (data != null)
{
    string creatorSID = Encoding.Unicode.GetString(data);
}

RegistryKey。SetValue

Edit:似乎您不需要将,字符转换为字节。

存储值:

var data = security.Split(',')
    .Select(x => Convert.ToByte(x, 16))
    .ToArray();
key.SetValue("creatorSID", data, RegistryValueKind.Binary);

返回值:

var data = (byte[])key.GetValue("creatorSID");
if (data != null)
{
    string creatorSID = string.Join(",", data.Select(x => x.ToString("x2")).ToArray());
}
