string[] out;

PS: if any predefined method is there that will also help

Answer 1

You can do that using Trim And Split :

var out = output.TrimStart('[').TrimEnd(']').Split(',');

But your data looks like JSON string. So, if you are dealing with JSON instead of making your own parser try using libraries that already does that such as JSON.NET .

Answer 2

You can use Trim functions to remove brackets and then use Split() function to get the string array that contains the substrings in this string that are delimited by elements of a specified Unicode character.

var res  = output.TrimStart('[')
                 .TrimEnd(']')
                 .Split(',');

Answer 3

string[] arr = output.Where(c => Char.IsDigit(c)).Select(c => c.ToString()).ToArray();

Answer 4

output.Substring(1, output.Length - 2).Split(',');
