怎么读注册表的二进制值和双字节值?

Answer 1

public int  GetRegData(string name)//读取
        {
            RegistryKey key = Registry.LocalMachine;
            RegistryKey software = key.OpenSubKey("SOFTWARE", true);
            RegistryKey hods = software.OpenSubKey("HODS", true);
            RegistryKey start = hods.OpenSubKey("START", true);
            int  keyData = Convert.ToInt32(start.GetValue(name));
            if (keyData == null)
            {
                start.SetValue(name, 0);
                keyData = 0;
            }
            return keyData;
        }        public void SetRegData(string name , int value)//设置
        {
            RegistryKey key = Registry.LocalMachine;
            RegistryKey software = key.OpenSubKey("SOFTWARE", true);
            RegistryKey hods = software.OpenSubKey("HODS",true);
            RegistryKey start = hods.OpenSubKey("START", true);
            start.SetValue(name, value);
        }

Answer 2

以上是读取和设置SOFTWARE-HODS-START下的双字节值。

Answer 3

读"双字节值"时 报错:未处理的“System.InvalidCastException”类型的异常出现在 mscorlib.dll 中。其他信息: Specified cast is not valid.

Answer 4

引用
using Microsoft.Win32
了吗?

Answer 5

当然用了using Microsoft.Win32            int  keyData = Convert.ToInt32(start.GetValue(name));
            if (keyData == null)start.GetValue(name)得到结果是byte[]类型啊

你的方法读"双字节值"是可以的

Answer 7

I know
using System.Text
Encoding.Unicode.GetString(start.GetValue(name));

Answer 8

注册表内的值是:REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\TEST]"Singer"=hex:61,75,74,68,6f,72,69,7a,61,74,69,6f,6e,00,00,00,00,00,00,00,00,00,\
  00,00,00,00

Answer 9

zxcayumi(◎_◎) 还没有解决:
把这下面一段内容复制到记事本中,然后另存为aa.reg文件,再运行aa.reg文件.就会把
Singer值导入到HKEY_LOCAL_MACHINE\SOFTWARE\TEST目录下.REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\TEST]"Singer"=hex:61,75,74,68,6f,72,69,7a,61,74,69,6f,6e,00,00,00,00,00,00,00,00,00,\
  00,00,00,00

Answer 10

zxcayumi(◎_◎) 麻烦你帮我试试,能不能读出来.

Answer 11

string keyData = Encoding.ASCII.GetString((byte[])(hods.GetValue("Singer"))) ;
