Build up a list of the running processes

 
using System;
using System.Collections.Generic;
using System.Diagnostics;
class MainClass {
    static void Main() {
        
        List<String> processes = new List<String>();
        foreach (Process process in Process.GetProcesses())
            processes.Add(process.ProcessName);
    }
}

CloseMainWindow,WaitForExit

 

using System;
using System.Threading;
using System.Diagnostics;
class MainClass
{
    public static void Main()
    {
        using (Process process = Process.Start("notepad.exe", @"c:\SomeFile.txt"))
        {

Enum Modules For Pid

 
using System;

            Console.WriteLine("bad PID!");
            return;
        }
        Console.WriteLine("Here are the loaded modules for: {0}", theProc.ProcessName);
        try {

            foreach (ProcessModule pm in theMods) {
                Console.WriteLine(string.Format("-> Mod Name: {0}", pm.ModuleName));
            }
        } catch { Console.WriteLine("No mods!"); }
    }

Get current Process Name

 
using System;
using System.Reflection;
using System.Diagnostics;
class AssemType

  {
    Process p = Process.GetCurrentProcess();
    string assemblyName = p.ProcessName + ".exe";

      Console.WriteLine("\nType : {0}",t.FullName);
      Console.WriteLine("\tBase class : {0}",t.BaseType.FullName);
    }
  }
}

Get Process property

using System;

      int priority = thisProc.BasePriority;
      ProcessPriorityClass priClass = thisProc.PriorityClass;
      TimeSpan cpuTime = thisProc.TotalProcessorTime;

      Console.WriteLine("Process: {0}, ID: {1}", procName, procID);
      Console.WriteLine("    started: {0}", started.ToString());
      Console.WriteLine("    CPU time: {0}", cpuTime.ToString());

      Console.WriteLine("    virtual memory: {0}", memory);
      Console.WriteLine("    private memory: {0}", priMemory);
      Console.WriteLine("    physical memory: {0}", physMemory);
      Console.WriteLine("\n    trying to change priority...");
      thisProc.PriorityClass = ProcessPriorityClass.High;
      priClass = thisProc.PriorityClass;
      Console.WriteLine("    new priority class: {0}", priClass);
   }
}

Get Threads

      ProcessThreadCollection myThreads = thisProc.Threads;
      foreach(ProcessThread pt in myThreads)
      {
         DateTime startTime = pt.StartTime;
         TimeSpan cpuTime = pt.TotalProcessorTime;
         int priority = pt.BasePriority;
         ThreadState ts = pt.ThreadState;
         Console.WriteLine("thread:  {0}", pt.Id);
         Console.WriteLine("    started: {0}", startTime.ToString());
         Console.WriteLine("    CPU time: {0}", cpuTime);
         Console.WriteLine("    priority: {0}", priority);
         Console.WriteLine("    thread state: {0}", ts.ToString()); 
      }
   }
}

Input Output:Starting Processes

using System.Diagnostics;
public class StartingProcesses
{
    public static void Main()
    {
        ProcessStartInfo startInfo = new ProcessStartInfo();
        startInfo.FileName = "notepad.exe";
        startInfo.Arguments = "process.cs";
        
        Process.Start(startInfo);
