Separate base64 from String

I don't think there are any magical solutions to such problems. You will obviously have to write a code for this.

Here is complete code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApp2
{
class Program
{
static void Main(string[] args)
{
String src = @"
"data: image / png; base64,iVBORw0KGgoAAAANSUh="" />
< img src = ""data:image/png;base64,/9j/4AAQSkZJRgABAQAAAQABAA="" /> ----------Reply message---------- From: a.b @gmail.com Date: 04 / 01 / 2018 02:50:19 PM Subject: Ticket No: gh To: a.f @muraai.com ";
List b64strings = getBase64Strings(src);
foreach (String s in b64strings)
Console.WriteLine(s);
Console.ReadKey();
}
private static List getBase64Strings(String source)
{
const String LOOK_FOR = "base64,";
List returnValue = new List();
Int32 start = 0; Int32 end = 0; Int32 position = 0; Int32 length = source.Length; Int32 lookforLength = LOOK_FOR.Length;
while (position < length)
{
start = source.IndexOf(LOOK_FOR, position);
if (start == -1)
break;
end = source.IndexOf("\"", start + 1);
String b64s = source.Substring(start + lookforLength, end - start - lookforLength);
returnValue.Add(b64s);
position = end + 1;
}
return returnValue;
}
}
}
