C#调用注册表，修改IE相关配置

最近在项目中遇到用C#调用注册表，修改IE选项高级选项卡中的“显示图片”复选框，用到的代码如下：

RegisterHelper.cs:

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using Microsoft.Win32;          //添加针对操作注册表的应用

</pre><pre name="code" class="csharp"> public class RegisterHelper    {        /// <summary>        /// 读取指定名称的注册表的值        /// </summary>        /// <param name="root"></param>        /// <param name="subKey"></param>        /// <param name="name"></param>        /// <returns></returns>        public static string GetRegistryData(RegistryKey root, string subKey, string name)        {            string registData = string.Empty;            RegistryKey myKey = root.OpenSubKey(subKey, true);            if (myKey != null)            {                registData = myKey.GetValue(name).ToString();            }            return registData;        }        /// <summary>        /// 向注册表中写数据        /// </summary>        /// <param name="root"></param>        /// <param name="subKey"></param>        /// <param name="keyName"></param>        /// <param name="keyValue"></param>        public static void SetRegistryData(RegistryKey root, string subKey, string keyName, string keyValue)        {            RegistryKey aimDir = root.CreateSubKey(subKey);            aimDir.SetValue(keyName, keyValue);        }        /// <summary>        /// 删除注册表中指定的注册项        /// </summary>        /// <param name="root"></param>        /// <param name="subKey"></param>        /// <param name="keyName"></param>        public static void DeleteRegist(RegistryKey root, string subKey, string keyName)        {            string[] subkeyNames;            RegistryKey myKey = root.OpenSubKey(subKey, true);            subkeyNames = myKey.GetSubKeyNames();            foreach (string aimKey in subkeyNames)            {                if (aimKey == keyName)                    myKey.DeleteSubKeyTree(keyName);            }         }        /// <summary>        /// 判断指定注册表项是否存在        /// </summary>        /// <param name="root"></param>        /// <param name="subKey"></param>        /// <param name="keyName"></param>        /// <returns></returns>        public static bool IsRegistryExits(RegistryKey root, string subKey, string keyName)        {            bool result = false;            string[] subKeyNames;            RegistryKey myKey = root.OpenSubKey(subKey, true);            subKeyNames = myKey.GetValueNames();            foreach (string name in subKeyNames)            {                if (name == keyName)                {                    result = true;                    return result;                }            }            return result;        }    }

调用方式：

需要引用以下命名空间

using System.Security.Principal;        //用户获取Windows SID 引用using Microsoft.Win32;

 //获取当前Windows用户            WindowsIdentity curUser = WindowsIdentity.GetCurrent();            //用户SID            SecurityIdentifier sid = curUser.User;            //用户全称            NTAccount ntacc = (NTAccount)sid.Translate(typeof(NTAccount));            Console.WriteLine("Windows SID:" + sid.Value);            Console.WriteLine("用户全称:" + ntacc.Value);            //IE选项中的“图片显示”操作在系统注册表中的路径为：HKEY_USERS\S-1-5-21-2145109174-1241497065-710993060-1001\Software\Microsoft\Internet Explorer\Main            //这个注册表下这个键值“Display Inline Images”,设置为yes或no，其中“S-1-5-21-2145109174-1241497065-710993060-1001”为Windows SID信息，在客户端使用的时候            //需要先获取（每个机器会不同）            //读注册表：            //RegistryHelper rh = new RegistryHelper();            //string portName = rh.GetRegistryData(Registry.LocalMachine, "SOFTWARE\\TagReceiver\\Params\\SerialPort", "PortName");            //写注册表：            //RegistryHelper rh = new RegistryHelper();            //rh.SetRegistryData(Registry.LocalMachine, "SOFTWARE\\TagReceiver\\Params\\SerialPort", "PortName", portName);                       //读取Display Inline Images            string displayImgPath = sid.Value + @"\Software\Microsoft\Internet Explorer\Main";            string displayImgValue = RegisterHelper.GetRegistryData(Registry.Users, displayImgPath, "Display Inline Images");            //IE选择中的“显示图片”勾选            if (displayImgValue == "yes")            {                //改变yes为no,将IE选项中的“显示图片”设置为不可用                RegisterHelper.SetRegistryData(Registry.Users, displayImgPath, "Display Inline Images", "no");                //重新打开浏览器                            }            Console.ReadKey();
