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);
        }

    }
