C# 创建动态数组并与静态数组进行比较

C# 创建动态数组并与静态数组进行比较,c#,regex,arrays,C#,Regex,Arrays,我正在尝试编写一个程序,扫描周围的WiFi网络,并将信息转储到包含SSID和加密类型的数组中。然后将SSID动态数组与尝试将SSID匹配在一起的静态数组进行比较,然后输出结果 我在尝试使用Regex创建动态数组时遇到了问题,只使用SSID和加密。网络转储的输出如下所示: Interface name : Wireless Network Connection There are 8 networks currently visible. SSID 1 : TheChinaClub-5G

我正在尝试编写一个程序,扫描周围的WiFi网络,并将信息转储到包含SSID和加密类型的数组中。然后将SSID动态数组与尝试将SSID匹配在一起的静态数组进行比较,然后输出结果

我在尝试使用Regex创建动态数组时遇到了问题,只使用SSID和加密。网络转储的输出如下所示:

Interface name : Wireless Network Connection 
There are 8 networks currently visible. 

SSID 1 : TheChinaClub-5G
    Network type            : Infrastructure
    Authentication          : WPA2-Personal
    Encryption              : CCMP 
我尝试使用SSID作为键,下面的数字作为通配符(但不知道语法),并获取冒号后面的数据,不包括空格。到目前为止,除了网络转储之外,其他功能都无法工作。正则表达式似乎找不到任何东西。我一直在使用正则表达式的模型

以下是迄今为止我掌握的代码:

        {
            x = SSID;
            y = Encryption;
        }
    }

     class Program
    {

        static void Main(string[] args)
        {

            p.Start();
            string results = p.StandardOutput.ReadToEnd();

            string[] SSIDs = { "SSID *"};

            FindSSIDs(SSIDs, results);

            Console.WriteLine(results);
            Console.ReadLine();




        }

        private static void FindSSIDs(IEnumerable<string> keywords, string source)
        {
            var found = new Dictionary<string, string>(10);
            var keys = string.Join("|", keywords.ToArray());
            var matches = Regex.Matches(source, @"(?<key>" + keys + "):",
                                  RegexOptions.IgnoreCase);

            foreach (Match m in matches)
            {

                found.Add(key, source.Substring(start, end - start));
            }

            foreach (var n in found)
            {

试试这个

try {
    Regex regexObj = new Regex(@"(?<=SSID\s*\d+ :\s*)(?<value>\S+)");
    Match matchResults = regexObj.Match(subjectString);
    while (matchResults.Success) {
        for (int i = 1; i < matchResults.Groups.Count; i++) {
            Group groupObj = matchResults.Groups[i];
            if (groupObj.Success) {
                // matched text: groupObj.Value
                // match start: groupObj.Index
                // match length: groupObj.Length
            } 
        }
        matchResults = matchResults.NextMatch();
    } 
} catch (ArgumentException ex) {
    // Syntax error in the regular expression
}
试试看{

Regex regexObj=new Regex(@)(?这很有效唯一的问题是,如果SSID中有空格,字符串只显示网络的第一个字。
