Filtering a line out of a string c#
<p>I want to read a .txt file in c# and filter a line out of the string and only show that line. If the match is on the first line, i get a good output using streamreader.ReadLine. But if it's on the second line, i need to get it filtered. (i tought by creating a ReadLine loop?)
Thanks in advance</p>

<pre><code>        private void comboBox3_SelectedIndexChanged(object sender, EventArgs e)
    {

        StreamReader sr = new StreamReader(textBox1.Text);
        string BoxLM1 = sr.ReadLine();

        if (comboBox3.Text == "Anderlecht")
        {
            if (BoxLM1.Contains("Anderlecht"))
            {
            label5.Text = BoxLM1;
            }

            else
            {
                string BoxLM2 = sr.ReadToEnd();



                    MessageBox.Show(BoxLM2);  

            }
</code></pre>
