问题描述

我要寻找对在C＃中的API，让我来控制转动连接和关闭我的Internet连接指针。

I am looking for pointers towards APIs in c# that will allow me to control my Internet connection by turning the connection on and off.

我想要写一个小控制台应用程序，这将让我打开和关闭我的访问，从而提高生产率猛增:)（以及在学习过程中的东西）

I want to write a little console app that will allow me to turn my access on and off , allowing for productivity to skyrocket :) (as well as learning something in the process)

谢谢！

推荐答案

如果你正在使用Windows Vista，您可以使用内置的防火墙，以阻止任何互联网连接。

If you're using Windows Vista you can use the built-in firewall to block any internet access.

以下code创建一个防火墙规则，阻止所有网络适配器的出站连接：

The following code creates a firewall rule that blocks any outgoing connections on all of your network adapters:

using NetFwTypeLib; // Located in FirewallAPI.dll
...
INetFwRule firewallRule = (INetFwRule)Activator.CreateInstance(
    Type.GetTypeFromProgID("HNetCfg.FWRule"));
firewallRule.Action = NET_FW_ACTION_.NET_FW_ACTION_BLOCK;
firewallRule.Description = "Used to block all internet access.";
firewallRule.Direction = NET_FW_RULE_DIRECTION_.NET_FW_RULE_DIR_OUT;
firewallRule.Enabled = true;
firewallRule.InterfaceTypes = "All";
firewallRule.Name = "Block Internet";

INetFwPolicy2 firewallPolicy = (INetFwPolicy2)Activator.CreateInstance(
    Type.GetTypeFromProgID("HNetCfg.FwPolicy2"));
firewallPolicy.Rules.Add(firewallRule);

然后，当你想再次让互联网接入删除的规则：

Then remove the rule when you want to allow internet access again:

INetFwPolicy2 firewallPolicy = (INetFwPolicy2)Activator.CreateInstance(
    Type.GetTypeFromProgID("HNetCfg.FwPolicy2"));
firewallPolicy.Rules.Remove("Block Internet");

这是一些其他的code，我已经使用了轻微的修改，所以我不能作出任何保证它会工作。再次，记住，你需要的Windows Vista（或更高版本）和管理权限进行这个工作。

This is a slight modification of some other code that I’ve used, so I can’t make any guarantees that it’ll work. Once again, keep in mind that you'll need Windows Vista (or later) and administrative privileges for this to work.
