Question

all

This question is related to two methods in System.IO.File:

File.WriteAllLines and File.ReadAllLines

When I save a List[string] ListA by using

File.WriteAllLines("filename",ListA.ToArray());

There will be an empty line append to the output file.

So each time I load this file by calling File.ReadAllLines, I will always get one more empty line.

It’s annoying, as I have to “remove” it manually each time.

Does anyone suffering same problem? And how you deal with it?

Thanks

Nope, I can’t reproduce that:

using System;
using System.Collections.Generic;
using System.IO;

class Test
{
    static void Main()
    {
        string[] lines = { "first", "second", "third" };

        for (int i = 0; i < 10; i++)
        {
            File.WriteAllLines("test.txt", lines);

            lines = File.ReadAllLines("test.txt");
            Console.WriteLine("Number of lines read: {0}", lines.Length);
        }
    }
}

It sounds like it’s probably something to do with what you’re doing with the lines… which you haven’t told us.
