How to get whole list of processes in decreasing order of their thread count ( C# )

Question

fig refers to task manager Resource monitor

` Process[] processlist = Process.GetProcesses(); foreach(Process theprocess in processlist){ Console.WriteLine(“Process: {0} ID: {1}”, theprocess.ProcessName, theprocess.Id); }` — METALHEAD, Jun 01 '15 at 06:09

You could try this,

Process[] processList = Process.GetProcesses().OrderByDescending(x => x.Threads.Count).ToArray();

@Kurubaran.....I am getting only one process with this...rundll32.exe which has only 1 thread.... – METALHEAD Jun 01 '15 at 08:55
@METALHEAD You meant above code retruns only one process ? if then something should be wrong. I tested that code and it works fine. – Kurubaran Jun 01 '15 at 09:24
Thanks...for your answer – METALHEAD Jun 18 '15 at 10:23
@METALHEAD You are welcome. – Kurubaran Jun 18 '15 at 11:47

You could do the following:

private void fuc()
{
    System.Diagnostics.Process[] procArray;
    procArray = System.Diagnostics.Process.GetProcesses();
    List<KeyValuePair<string, int>> threads = new List<KeyValuePair<string,int>>();
    for (int i = 0; i < procArray.Length; i++)
    {
        var element = new KeyValuePair<string, int>(procArray[i].ProcessName, procArray[i].Threads.Count);
        threads.Add(element);
    }
    threads.Sort(OrderAsc);
}

static int OrderAsc(KeyValuePair<string, int> a, KeyValuePair<string, int> b)
{
     return a.Value.CompareTo(b.Value);
}

Its a big code (can become more compact)......but finally got the answer....thank you so much @kuruban @Gnqz @utility @derape

            System.Diagnostics.Process[] procArray;
            procArray = System.Diagnostics.Process.GetProcesses();
            String[,] arr = new String[300,2];
            String max, maxi;
            int k;
            for (k = 0; k < procArray.Length; k++)
            {
                arr[k, 0] = procArray[k].ProcessName;
                arr[k, 1] = (procArray[k].Threads.Count).ToString();

            }
            for (int i = 0; i < procArray.Length; i++)
            {
               Console.WriteLine("{0} {1}", arr[i, 0], arr[i, 1]);

            }                        

        }
