const string oldPointer = "Old-Values: ";
var text = "New-Value = 12,34   -- Old-Values: 12,31,";
var old = text.Substring(text.IndexOf(oldPointer) + oldPointer.Length).TrimEnd(',');

Not very clear if this is a fixed (static) format of your string, but by the way:

A simple solution could be:

string str = "New-Value = 12,34   -- Old-Values: 12,31,"; 
str.Substring(str.IndexOf(':') + 1);

More complex one should involve Regular expressions, like an answer of L.B or others if any.

Regex.Match("New-Value = 12,34 -- Old-Values: 12,31,",@"\:(.+)\,").Groups[1].Value.Trim()
