在 vb.net 中以编程方式更改 Internet Explorer 代理（包括密码）而无需重新启动 ie

Question

有可能吗？

我知道一种方法是更改​​注册表。然而，必须有更好的方法。

共享子EnableProxy1()

Dim regKey As Microsoft.Win32.RegistryKey

regKey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software\Microsoft\Windows\CurrentVersion\Internet Settings", True)
regKey.SetValue("ProxyEnable", True, Microsoft.Win32.RegistryValueKind.DWord)
regKey.SetValue("ProxyServer", proxyhandler.proxyFedtoInternetExplorer, Microsoft.Win32.RegistryValueKind.String)
regKey.SetValue("ProxyOverride", "<local>", Microsoft.Win32.RegistryValueKind.String)
regKey.Close()

结束子

共享子DisableProxy() Dim regKey As Microsoft.Win32.RegistryKey

regKey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software\Microsoft\Windows\CurrentVersion\Internet Settings", True)

regKey.SetValue("ProxyEnable", False, Microsoft.Win32.RegistryValueKind.DWord)

regKey.Close()

End Sub

这样做有两个缺点

1. 我需要重新启动 Internet Explorer
2. 我需要通过直接操作 Windows 来更改代理的用户名和密码。

我想要一种更好、更直接的方法。有什么办法吗？
