Use a regex:

C#

public static Regex regex = new Regex(
      "(?<=Saldo:\\sRp\\s+)[\\d,\\.]*(?=,\\s)",
    RegexOptions.Multiline
    | RegexOptions.IgnorePatternWhitespace
    | RegexOptions.Compiled
    );
...
// Capture the first Match, if any, in the InputText
Match m = regex.Match(InputText);
if (m.Success)
   {
   string value = m.Value;
   ...

That's a trivial modification - you should be able to work it out for yourself.
Get a copy of Expresso

It's free, and it examines and generates Regular expressions.
It'll help you design and test regexes.
If you can't get it, show us what you tried.

The original string is:

Isi Voucher Regular 10K seharga Rp 10,400.00 pada 13/12/16 16:52 ke 6285811111111 SUKSES, Saldo: Rp 3,482,350.00, TID:0071272220111111111.

In the code you searh the first "," with

int endIndex = strKeterangan.IndexOf(",", startIndex);

this find the "," inside 3,482,350.00
if you use LastIndexOf to search the last "," in the string with:

int endIndex = strKeterangan.LastIndexOf(",", startIndex);

you will find what you want

Try the regex way:

using System;
using System.Text.RegularExpressions;

public class Program
{
	public static void Main()
	{
		string str = "Isi Voucher Regular 10K seharga Rp 10,400.00 pada 13/12/16 16:52 ke 6285811111111 SUKSES, Saldo: Rp 3,482,350.00, TID:0071272220111111111.";
		Regex regex = new Regex(@"Saldo: Rp [\d,\.]+(?=,)");
		Match match = regex.Match(str);
		if (match.Success)
		{
			Console.WriteLine(match.Value);
		}
	}
}
