In this case, you could use string.split() on the "|" character. Otherwise, you could use .substring and start at .length - 6. – Terry Tyson Apr 26 '21 at 20:36

Using .Split would look like this:
string myString = "BOB3 27QK DEPM PJ7J T25G SJZI CJA5 BO5O|123456";
char[] mySplitChars = { '|' };
string[] myArray = myString.Split(mySplitChars);
Console.WriteLine(myArray[1]);
Using .Substring would look like this:
Console.WriteLine(myString.Substring(myString.Length - 6));
The latter is probably preferred because it is shorter and it does not rely on the "|" character being present. The former would be preferred if the "|" is always present but the number of characters at the end can change.

How are you passing it your text box? If it's just getting the last n characters: refer to this answer
