我正在编写一个winforms应用程序,需要设置Internet Explorer的代理设置,然后打开一个新的浏览器窗口.目前,我正在通过进入注册表来应用代理设置:
RegistryKey registry = Registry.CurrentUser.OpenSubKey("Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings", true); registry.SetValue("ProxyEnable", 1); registry.SetValue("ProxyServer", "127.0.0.1:8080");
进入注册表是最好的方法,还是有更推荐的方法?如果有替代解决方案,我想避免注册表更改.
这取决于您的确切需求.如果您正在编写C#应用程序并且只想设置应用程序将使用的默认代理设置,请使用System.Net.GlobalProxySelection类(http://msdn.microsoft.com/en-us/library/system.net .globalproxyselection.aspx).您还可以使用System.Net.WebProxy(http://msdn.microsoft.com/en-us/library/system.net.webproxy.aspx)为任何特定连接设置代理.
如果您确实想要更新注册表中的代理设置,我相信您需要使用P/Invoke来调用WinAPI函数WinHttpSetDefaultProxyConfiguration(http://msdn.microsoft.com/en-us/library/aa384113. aspx).

在代码的开头添加以下行:
使用System.Runtime.InteropServices; 使用Microsoft.Win32;
[DllImport("wininet.dll")] public static extern bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer, int dwBufferLength); public const int INTERNET_OPTION_SETTINGS_CHANGED = 39; public const int INTERNET_OPTION_REFRESH = 37; bool settingsReturn, refreshReturn;
并暗示代码:
RegKey.SetValue("ProxyServer", YOURPROXY); RegKey.SetValue("ProxyEnable", 1); // These lines implement the Interface in the beginning of program // They cause the OS to refresh the settings, causing IP to realy update settingsReturn = InternetSetOption(IntPtr.Zero, INTERNET_OPTION_SETTINGS_CHANGED, IntPtr.Zero, 0); refreshReturn = InternetSetOption(IntPtr.Zero, INTERNET_OPTION_REFRESH, IntPtr.Zero, 0);
我写了一个10行程序来做到这一点,随时尝试https://github.com/131/proxytoggle
using System; using System.Collections.Generic; using System.Text; using System.Runtime.InteropServices; using Microsoft.Win32; namespace ProxyToggle { class Program { [DllImport("wininet.dll")] public static extern bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer, int dwBufferLength); public const int INTERNET_OPTION_SETTINGS_CHANGED = 39; public const int INTERNET_OPTION_REFRESH = 37; static void setProxy(string proxyhost, bool proxyEnabled) { const string userRoot = "HKEY_CURRENT_USER"; const string subkey = "Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings"; const string keyName = userRoot + "\\" + subkey; Registry.SetValue(keyName, "ProxyServer", proxyhost); Registry.SetValue(keyName, "ProxyEnable", proxyEnabled?"1": "0"); // These lines implement the Interface in the beginning of program // They cause the OS to refresh the settings, causing IP to realy update InternetSetOption(IntPtr.Zero, INTERNET_OPTION_SETTINGS_CHANGED, IntPtr.Zero, 0); InternetSetOption(IntPtr.Zero, INTERNET_OPTION_REFRESH, IntPtr.Zero, 0); } static void Main(string[] args) { if (args.Length == 0) { setProxy("", false); return; } setProxy(args[0], true); } } }

简短版本是您要使用InternetOpen,InternetSetOption API来更新代理设置.
