C#修改wifi连接

以下是使用C#修改WiFi连接的示例代码：

using System;
using System.Management;

public class WifiManager
{
    public static void ChangeWifiConnection(string ssid, string password)
    {
        ManagementClass wifiClass = new ManagementClass("root\\WMI", "MSNdis_80211_ServiceSetIdentifier", new ObjectGetOptions());
        ManagementObjectCollection wifiInstances = wifiClass.GetInstances();

        foreach (ManagementObject wifiInstance in wifiInstances)
        {
            string currentSsid = wifiInstance["Element"] as string;
            if (currentSsid == ssid)
            {
                ManagementBaseObject wifiMethod = wifiInstance.GetMethodParameters("SetElement");
                wifiMethod["Data"] = Convert.FromBase64String(password);
                wifiInstance.InvokeMethod("SetElement", wifiMethod, null);
                break;
            }
        }
    }
}

public class Program
{
    public static void Main(string[] args)
    {
        string ssid = "YourWifiSSID";
        string password = "YourWifiPassword";

        WifiManager.ChangeWifiConnection(ssid, password);
        Console.WriteLine("WiFi connection changed successfully.");
    }
}

这段代码使用了`ManagementClass`和`ManagementObject`类来访问WMI（Windows Management Instrumentation）并修改WiFi连接。首先，我们获取所有的WiFi实例，然后遍历每个实例，找到与指定SSID匹配的WiFi连接。一旦找到匹配的连接，我们使用`SetElement`方法来设置连接的密码。

请注意，这段代码需要在管理员权限下运行，否则可能无法修改WiFi连接。
