How to parse this kind of output in c#

I have output in following format

Image Name                     PID Services                                    
========================= ======== ============================================
System Idle Process              0 N/A                                         
services.exe                   436 N/A                                         
svchost.exe                    500 BrokerInfrastructure, DcomLaunch, LSM,      
                                   PlugPlay, Power, SystemEventsBroker         
vnetd.exe                    18504 NetBackup Legacy Network Service

I want to store the output in an array like this:

ar[0]=System Idle Process
ar[1]=0
ar[2]=N/A

I tried to split the string on the basis of whitespace but it didnt worked out. Can anyone suggest how to split this and get the desired output in c#

It looks like the information you are receiving has a fixed width output, so, you can just use string.Substring to get each time a part of the string as you want.

You could read the items in your input like so:

public static IEnumerable<ProcessItem> GetItemsFromText(string text) {
    var lines = text.Split( new [] { "\r", "\n" }, StringSplitOptions.RemoveEmptyEntries );
    ProcessItem current = null;
    Console.WriteLine( "Lines found: {0}", lines.Length );
    // skip first 2 lines (header and = signs)
    for (int i = 2; i < lines.Length; i++) {
        var name = lines[i].Substring( 0, 25 ).Trim();
        var pid = lines[i].Substring( 26, 8 ).Trim();
        var services = lines[i].Substring( 35 ).Trim();
        if (!string.IsNullOrWhiteSpace( name ) ) {
            if (current != null) {
                yield return current;
            }
            current = new ProcessItem {
                Name = name,
                Pid = pid,
                Services = services
            };
        } else {
            current.Services += ' ' + services;
        }
    }
    if (current != null) {
        yield return current;
    }
}

This version would also acknowledge that you have multi line items, and would send back a custom class ProcessItem that looks like the following

public class ProcessItem {
    public string Name { get; set; }
    public string Pid { get;set; }
    public string Services { get;set; }
}

A running version of the code you can find back in this .netfiddle

use substring on the basis of padding 

formatedop[0] = item.Substring(0, 25);
formatedop[1] = item.Substring(25, 10);
formatedop[2] = item.Substring(35, 40);

it will give the result
