开放的网络，象ChinaNet这种，是没有配置文件的

中间这一段： foreach (Wlan.WlanProfileInfo profileInfo in wlanIface.GetProfiles()) { string name = profileInfo.profileName; // this is typically the network's SSID string xml = wlanIface.GetProfileXml(profileInfo.profileName); } 是系统中已有的xml配置，你用Console.WriteLine或调试看看这些xml配置是怎样的，系统中的配置是肯定正确的，然后你参考它改改。

验证了一下你的代码，有点问题，报“网络连接配置文件已损坏。”异常！！ <keyMaterial>{2}</keyMaterial>这个地方的密码应该用加过密之后的值吧

下载这个：http://managedwifi.codeplex.com/ 例子：


namespace WifiExample
{
	using NativeWifi;
	using System;
	using System.Text;

	internal class Program
	{
		/// <summary>
		/// Converts a 802.11 SSID to a string.
		/// </summary>
		private static string GetStringForSSID(Wlan.Dot11Ssid ssid)
		{
			return Encoding.ASCII.GetString(ssid.SSID, 0, (int) ssid.SSIDLength);
		}

		private static void Main(string[] args)
		{
			WlanClient client = new WlanClient();
			foreach (WlanClient.WlanInterface wlanIface in client.Interfaces)
			{
				// Lists all networks with WEP security
				Wlan.WlanAvailableNetwork[] networks = wlanIface.GetAvailableNetworkList(0);
				foreach (Wlan.WlanAvailableNetwork network in networks)
				{
					if (network.dot11DefaultCipherAlgorithm == Wlan.Dot11CipherAlgorithm.WEP)
					{
						Console.WriteLine("Found WEP network with SSID {0}.", GetStringForSSID(network.dot11Ssid));
					}
				}

				// Retrieves XML configurations of existing profiles.
				// This can assist you in constructing your own XML configuration
				// (that is, it will give you an example to follow).
				foreach (Wlan.WlanProfileInfo profileInfo in wlanIface.GetProfiles())
				{
					string name = profileInfo.profileName; // this is typically the network's SSID
					string xml = wlanIface.GetProfileXml(profileInfo.profileName);
				}

				// Connects to a known network with WEP security
				string profileName = "Cheesecake"; // 改成要连接的无线网的 SSID
				string key = "hello"; // 改成连接密码
				string mac = wlanIface.NetworkInterface.GetPhysicalAddress().ToString();
				string profileXml = string.Format(@"<?xml version=""1.0""?>
					<WLANProfile xmlns=""http://www.microsoft.com/networking/WLAN/profile/v1"">
						<name>{0}</name>
						<SSIDConfig>

				wlanIface.SetProfile(Wlan.WlanProfileFlags.AllUser, profileXml, true);
				wlanIface.Connect(Wlan.WlanConnectionMode.Profile, Wlan.Dot11BssType.Any, profileName);
			}
		}
