我有一些代码，我目前正在使用这些代码来更改网络适配器的静态 IP。在 Windows XP 32 位机器（物理和虚拟机）上运行时，设置 IP 地址时会稍有停顿（约 1 秒），但似乎确实会更改 IP。
在 Windows 7 64 位机器上运行时，它无法更改 IP 地址。尝试进行更改时不会暂停，也不会引发异常。
我已经进行了大量的谷歌搜索，大多数建议似乎只是以管理员身份运行。我尝试右键单击可执行文件并选择“以管理员身份运行”，我尝试创建快捷方式并将其设置为以管理员身份运行，并且我尝试更新清单文件（它确实要求管理员权限）启动，但仍不更改 IP 地址。）
任何人都可以提供任何建议吗？
代码如下：

// First display all network adaptors
DisplayNetworkAdaptors(-1);
// Now try to set static IP, subnet mask and default gateway for adaptor with
// index of 1 (may be different for your machine!)
SetIP(1,
new string[] { "10.10.1.222" },
new string[] { "255.255.255.0" },
new string[] { "10.10.1.10" });
// Now display network adaptor settings for adaptor 1 (may be different for your machine!)
DisplayNetworkAdaptors(1);
