如何在C#控制台應用程序中顯示專門運行應用程序的進程列表

我制作了一個控制台應用程序，就像一個任務管理器，用戶可以在其中啟動、查看和終止進程。 然后有查看進程、查看全部、查看正在運行的應用程序、查看后台進程和系統進程的選項。 我已經完成了“查看全部”選項的第一個選項，但我無法完成其他 3 個選項。

我的代碼在下面...

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;
using System.Runtime.InteropServices;

namespace taskManager
{
    class Program
    {
        static void Main(string[] args)
        {
            string a;
            intro:
            Console.WriteLine("OPTIONS:");
            Console.WriteLine("1. Start Process");
            Console.WriteLine("2. View Process");
            Console.WriteLine("3. Terminate a Process");
            Console.Write("Enter Option:");
            a = Console.ReadLine();
            if (a == "1") goto start;
            if (a == "2") goto view;
            if (a == "3") goto terminate;
            Console.WriteLine("Invalid option!");
            goto intro;
            start:
            { 
                Console.WriteLine("Enter Process name:");
                a = Console.ReadLine();
                Process.Start(a);
                goto intro;
            }
            view:
            { 
                Console.WriteLine("OPTIONS for View:");
                Console.WriteLine("a. View all");
                Console.WriteLine("b. View Applications");
                Console.WriteLine("c. View Background process");
                Console.WriteLine("d. View System Process");
                Console.Write("Enter Option:");
                a=Console.ReadLine();
                if (a == "a") goto a;
                if (a == "b") goto b;
                a:
                {
                    Console.WriteLine("Processes");
                    Process[] processes = Process.GetProcesses();
                    Console.WriteLine("No. Of Pocess: {0}", processes.Length);
                    foreach (Process process in processes)
                    {
                        Console.WriteLine(process.ProcessName);
                    }
                    goto intro;
                }
    //This is where the unaccomplished options
        b:Apps
        c:background Process
        d:System process
            }
            terminate:
            {
                Console.WriteLine("Enter process name:");
                a = Console.ReadLine();
                foreach (var process in Process.GetProcessesByName(a))
                {
                    process.Kill();

                }
                Console.WriteLine("Process terminated!");
                goto intro;
            }
        }
    }
}
