在C#中操作注册表

using Microsoft.Win32;
    using System.Diagnostics;
    private void Access_Registry()
    {
         // 在HKEY_LOCAL_MACHINESoftware下建立一新键，起名为MCBInc
            RegistryKey key = Registry.LocalMachine.OpenSubKey("Software", true);
         // 增加一个子键
            RegistryKey newkey = key.CreateSubKey("MCBInc");    // 设置此子键的值
            newkey.SetValue("MCBInc", "NET Developer");  // 从注册表的其他地方获取数据  // 找出你的CPU
            RegistryKey pRegKey = Registry.LocalMachine;
            pRegKey = pRegKey.OpenSubKey("HARDWAREDESCRIPTIONSystemCentralProcessor");
            Object val = pRegKey.GetValue("VendorIdentifier");
            Debug.WriteLine("The central processor of this machine is:"+ val);
         // 删除键值
            RegistryKey delKey = Registry.LocalMachine.OpenSubKey("Software", true);
            delKey.DeleteSubKey("MCBInc");
