c# filter for multiple lines
<p>Hey guys I need some help;
I have <code>something.txt</code> that contains</p>

<pre><code>4   10:06:29      0      0          0

2   10:06:30      0      0          0

7   10:06:31      0      0          0
</code></pre>

<p>something in format like that</p>

<p>then I have some code</p>

<pre><code>System.IO.StreamReader file = new System.IO.StreamReader(path);
var lines1 = File.ReadAllLines(path).First(s =&gt; s.StartsWith(tempvar));
listBox1.Items.Add(lines1);
</code></pre>

my code does this for the first line that he found in file (.txt file), need some help for multiple lines</p>
