如何加载多行文本文件？

Question

I have some textfiles which look similar to the following one:

0,75;1,20;true;4,50;4,30;3,30;false
0,75;1,20;true;4,50;4,30;4,30;true

I load the textfile like this:

private const string filename = "Data.txt";
string[] strs;
public void LoadTextfile()
    {
        System.IO.Stream stream = TitleContainer.OpenStream(filename);
        System.IO.StreamReader reader = new System.IO.StreamReader(stream);       
        strs = reader.ReadLine().Split(';');
        game1.StatsList.Add(new Containerclass.StatsContainer(float.Parse(strs[0], culture), float.Parse(strs[1], culture), bool.Parse(strs[2]), float.Parse(strs[3], culture), float.Parse(strs[4], culture), float.Parse(strs[5], culture), bool.Parse(strs[6])));        
        strs = reader.ReadLine().Split(';');
        game1.StatsList.Add(new Containerclass.StatsContainer(float.Parse(strs[0], culture), float.Parse(strs[1], culture), bool.Parse(strs[2]), float.Parse(strs[3], culture), float.Parse(strs[4], culture), float.Parse(strs[5], culture), bool.Parse(strs[6])));        

But my textfiles have much more entries(more than 100) than the textfile above. In addition, I don't know the number of rows of any textfile. Maybe one textfile has 110 rows, the second textfile 150 rows, etc. Is it possible to load everything with a loop if I don't know the number of rows? Which loop should I use to load the entire textfile? I know that I can not use a for-loop because I don't know how much rows the textfile has, is it possible to load it with another loop? Or is it not possible to load an entire textfile with one loop?

File.ReadLines(string path) is really nice

string[] lines = File.ReadLines("filename.txt").ToArray();

If you really want to get fancy, you can try some linq

game1.StatsList = File.ReadLines("Data.txt")
    .Select(s => 
    {
        var strs = s.Split(';');
        return new Containerclass.StatsContainer(float.Parse(strs[0], culture), float.Parse(strs[1], culture), bool.Parse(strs[2]), float.Parse(strs[3], culture), float.Parse(strs[4], culture), float.Parse(strs[5], culture), bool.Parse(strs[6]));
    })
    .ToList();

Note that a for loop can be run without explicitly knowing the number of elements to iterate over - the central statement can be any conditional evaluating to a bool , not just i < number

using (var reader = new StreamReader(stream))
{
    for(string line = reader.ReadLine();
        reader.EndOfFile == false;
        line = reader.ReadLine())
    {
        //...
    }
}

Using File.ReadLines will also allow you to iterate over each line using a foreach -

foreach(string line in File.ReadLines(filename))
{
    //...
}

Being a little more explicit, you can also use StreamReader.ReadToEnd and Splt the results

foreach(var line in new StreamReader(stream)
    .ReadToEnd()
    .Split(new [] {"\r\n" }, StringSplitOptions.RemoveEmptyEntries)
{
    //...
}
