Loading text file into listbox
提问by Shannon Rothe
What I am wanting to achieve is loading a text file into a listbox. It seems simple enough but I need to recognise in the text file when there is a new line, and each new line needs to be a new item in the listbox.
我想要实现的是将文本文件加载到列表框中。这看起来很简单，但我需要在文本文件中识别新行，并且每个新行都需要是列表框中的一个新项目。
If this is possible, a reply would be much appreciated.
如果这是可能的，答复将不胜感激。

This will work
这将工作
List<string> lines = new List<string>();
using (StreamReader r = new StreamReader(f))
{
string line;
while ((line = r.ReadLine()) != null)
{
lines.Add(line);
}
}

Try something like this:
尝试这样的事情：
listboxObject.DataSource = File.ReadAllLines("PathToYourFileHere");
回答by Michel Keijzers
You can read all text (file.ReadAllText or Alllines), I don't have a compiler here.
您可以阅读所有文本（file.ReadAllText 或 Alllines），我这里没有编译器。
Then add them to the list box, it is advised to trim the lines to get rid of whitespace at the beginning and end of each line.
然后将它们添加到列表框中，建议修剪行以去除每行开头和结尾的空格。

OpenFileDialog f = new OpenFileDialog();
if (f.ShowDialog() ==DialogResult.OK)
{
listBox1.Items.Clear();
List<string> lines = new List<string>();
using (StreamReader r = new StreamReader(f.OpenFile()))
{
string line;
while ((line = r.ReadLine()) != null)
{
listBox1.Items.Add(line);
}
}
}
