C#修改注册表（IE），以修改IE代理服务器为例：

using System;
using System.Collections;
using System.Threading;
using System.Runtime.InteropServices;
using System.Diagnostics;
using Microsoft.Win32;

namespace TestBlog
{
class Program
{
[DllImport(@"wininet",
SetLastError = true,
CharSet = CharSet.Auto,
EntryPoint = "InternetSetOption",
CallingConvention = CallingConvention.StdCall)]

public static extern bool InternetSetOption
(
int hInternet,
int dmOption,
IntPtr lpBuffer,
int dwBufferLength
);

public static void SetProxy(string proxy)
{
//打开注册表
RegistryKey regKey = Registry.CurrentUser;
string SubKeyPath = @"Software/Microsoft/Windows/CurrentVersion/Internet Settings";
RegistryKey optionKey = regKey.OpenSubKey(SubKeyPath, true);
//更改健值，设置代理，
optionKey.SetValue("ProxyEnable", 1);
optionKey.SetValue("ProxyServer", proxy);

//激活代理设置
InternetSetOption(0, 39, IntPtr.Zero, 0);
InternetSetOption(0, 37, IntPtr.Zero, 0);
}

}
