CodePudding user response：

You are trying to extract a specific word from a sentence, and in your case the word that we are trying to extract happens to be the first one.

With an assumption that the input is an array of strings, we can use split method on sentences which contain the word 'device' and get the item at the 0th index.

This is how you would do it,

List<string> inputData = new List<string>()
{
    "List of devices attached",
    "adb server is out of date. killing...",
    "daemon started successfully *",
        "AIE00202523 device",
        "f050354 device",
        "f050355 device",
        "AIE0020257 device",
        "AIE0020259 device",
        "f050346 device",
        "f050352 device",
        "AIE00202520 device"
};

Console.WriteLine("Devices");

foreach(var line in inputData)
{
    if (Regex.IsMatch(line, "device$"))
    {
        string deviceName = line.Split(' ')[0];
        Console.WriteLine(deviceName);
    }
}

devices_str = devices_str.Replace(" device", string.Empty);

string[] devices = devices_str.Split('\n');

foreach (string device in devices) {
    System.Console.WriteLine(device);
