查找数字并保存到字符串

我正在尝试制作一个可以获取网络上计算机会话ID的ui。我想获取此会话ID并将其保存到字符串中以备后用。

    private void button1_Click(object sender, EventArgs e)
    {
        string ComputerName = ComputerNameBox.Text;
        string Username = UserNameBox.Text;

        Process Process = new Process();
        Process.StartInfo.FileName = "CMD.exe";
        Process.StartInfo.Arguments = "/K" + "qwinsta /server:" + ComputerName + " " + Username;
        Process.StartInfo.CreateNoWindow = true;
        Process.StartInfo.UseShellExecute = false;
        Process.StartInfo.RedirectStandardOutput = true;

        Process.Start();

        Process.OutputDataReceived += new DataReceivedEventHandler(SortOutputHandler);

        Process.BeginOutputReadLine();
        while (!Process.HasExited)
        {
            Application.DoEvents();
        }

    }
    private void SortOutputHandler(object sendingProcess, DataReceivedEventArgs outLine)
    {
        if (MessagePop.InvokeRequired)
        {
            MessagePop.BeginInvoke(new DataReceivedEventHandler(SortOutputHandler), new[] { sendingProcess, outLine });
        }
        else
        {
            MessagePop.AppendText(Environment.NewLine + outLine.Data);
        }
    }

此代码运行并输入您要为其使用会话ID的计算机/人员的计算机名和用户名。用户名和ID每次可能都不同，因此我无法对其进行硬编码。

SESSIONNAME       USERNAME                 ID  STATE   TYPE        DEVICE
console           mlynch                    9  Active

这是我在文本框中获得的输出，我想获取9并将其保存到字符串中，但是，该数字可以是大约10或更高的值，因此我将需要能够同时获得两个数字。我该怎么做呢？

我想出了我该怎么做。

                Process GetSessionID = new Process();
                GetSessionID.StartInfo.FileName = "CMD.exe";
                GetSessionID.StartInfo.Arguments = "/C" + "for /f \"skip=1 tokens=3\" %1 in ('query user " + Username + "/server:" + ComputerName + "') do @echo %1";
                GetSessionID.StartInfo.RedirectStandardOutput = true;
                GetSessionID.StartInfo.UseShellExecute = false;
                GetSessionID.StartInfo.CreateNoWindow = true;
                GetSessionID.Start();
                SessionIDOutput = GetSessionID.StandardOutput.ReadToEnd();
                GetSessionID.WaitForExit();
                DoAllTheThingsTextBox.Text = SessionIDOutput;
                if (GetSessionID.HasExited == true)
                {
                    var digitArray = DoAllTheThingsTextBox.Text.Where(Char.IsDigit).ToArray();
                    SessionID = new String(digitArray);

                    if (MouseControlCheck.Checked == true)
                    {
                        Process Process = new Process();
                        ProcessStartInfo startInfo = new ProcessStartInfo("CMD.exe", "/C" + "mstsc /shadow:" + SessionID + " /v " + ComputerName + " /control");
                        startInfo.CreateNoWindow = true;
                        startInfo.UseShellExecute = false;

                        Process = Process.Start(startInfo);
                    }
                    else
                    {
                        Process Process = new Process();
                        ProcessStartInfo startInfo = new ProcessStartInfo("CMD.exe", "/C" + "mstsc /shadow:" + SessionID + " /v " + ComputerName);
                        startInfo.CreateNoWindow = true;
                        startInfo.UseShellExecute = false;

                        Process = Process.Start(startInfo);
                    }
                }
