在二进制值中将Stringformated Hex块写入注册表
我真的被某事搞定了。 我有一个包含hex值的字符串：
string creatorSid = @“01,05,00,00,00,00,00,05,15,00,00,00,10，b1,9d，4a，7a，85,7b，05,79,05，b3 ，7c中，EE，03,00,00″ ;
我想把它放到需要二进制值的registrykey中。
我试过这个：
key.SetValue（“creatorSID”，creatorSid，RegistryValueKind.Binary）;
但是我收到了无法转换的错误消息。
到目前为止，这是完整的代码：
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); } } } 它现在正在编写条目，但值已更改。 如果我检查钥匙，其中有“30 00 31 00 …..”。 但必须是：“01 00 0c 80 …..”（必须是字符串中的值）
当你有字符串时，你必须使用RegistryValueKind.String 。
key.SetValue("creatorSID", creatorSid , RegistryValueKind.String);
如果你需要使用RegistryValueKind.Binary ，你需要将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);
要获得价值：
var data = (byte[])key.GetValue("creatorSID"); if (data != null) { string creatorSID = Encoding.Unicode.GetString(data); }
RegistryKey.SetValue
编辑：似乎你不需要将字符转换为字节。 请尝试以下方法。
存储值：
var data = security.Split(',') .Select(x => Convert.ToByte(x, 16)) .ToArray(); key.SetValue("creatorSID", data, RegistryValueKind.Binary);
要获得价值：
var data = (byte[])key.GetValue("creatorSID"); if (data != null) { string creatorSID = string.Join(",", data.Select(x => x.ToString("x2")).ToArray()); }
