c＃ - 从文本文件中读取行并添加到列表框中

Question

I think my question is simple. I've searched but not found a solution for the method that I'm actually using.
I save the content of a listbox into a text file with success, but I'm having problem on load. For create the file, I use:

using(StreamWriter file = File.CreateText(path))

To write the content from the listbox to file, I use:

foreach (string content in listDOF.Items)
{
    file.WriteLine(content);
}

This works very well.
Now, I just need load the saved content with succes. I've tried:

if (File.Exists(filesrc))
{
    File.OpenRead(filesrc);
    string[] line = System.IO.File.ReadAllLines(filesrc);
    listDOF.Items.Add(line);
}

But this does not work and give me an exception.
How to do this correctily? Thanks all in advance! :)

Answer 1

You are adding an array of strings. The method to use is AddRange

string[] lines = System.IO.File.ReadAllLines(filesrc);
listDOF.Items.AddRange(lines);

The File.OpenRead is not needed. You could remove that line
