ASP.NET Removing Items from a list array by checking for certain value

Question

So I am reading a text file which may or may not end with some lines ending 9999999999999999999999999

which are just extra lines to make up a batch...im reading in the file like this

var lines = 
 File.ReadAllLines("C:\\Users\\Downloads\\EmployeeExpenseReimbACH_20111214.txt");

How can I loop through this and remove the lines with 9999999's? and then end up with an array without them basically.

You can use LINQ:

using System.Linq;

var path = "C:\\Users\\Downloads\\EmployeeExpenseReimbACH_20111214.txt";
var lines = File.ReadAllLines(path).Where(x => !x.EndsWith("99999"));

And if the line only has 999?

OP stated that the lines end with 9999999999999999999999999. And I assume he'd be able to determine whatever argument he needs to supply to EndsWith to make sure any lines will be removed that need to be. Why should I make the answer more complicated than required?

Yes, definitely dive into LINQ. It can make life so much easier sometimes. Glad I could help!
