How to skip first line while reading csv using streamreader
<p>I have my following code to read values from csv file and do some processing. I would like to skip the first row of the input csv file as it contains header text but I'd want to add it back after the processing is done.</p>

<pre><code>            List&lt;string&gt; values = new List&lt;string&gt;();
            using (StreamReader sr = new StreamReader(filePath))
            {
                while (sr.Peek() != -1)
                {
                    string line = sr.ReadLine();
                    List&lt;string&gt; lineValues = line.Split(',').ToList();
                    var tempMinInt = 1;
                    var tempValue = 1;
                    var tempValInt = Convert.ToInt32(lineValues[4]);
                    if (lineValues[3] == "1876")
                    {
                        if (tempValInt % 60 != 0)
                        {
                            tempMinInt = (tempValInt / 60) + 1;
                            tempValue = tempMinInt * 30;
                        }
                        else
                        {
                            tempMinInt = tempValInt / 60;
                            tempValue = tempMinInt * 30;
                        }
                    }
                    else if (lineValues[3] == "1875")
                    {
                        if (tempValInt != 0)
                        {
                            tempValue = 500;
                        }
                        else
                            tempValue = 0;
                    }

                    if (lineValues[3] == "1876")
                    {
                        values.Add(string.Join(",", lineValues) + "," + "0" + "," + "30" + "," + tempValue.ToString());
                    }
                    else if (lineValues[3] == "1875")
                    {
                        values.Add(string.Join(",", lineValues) + "," + "1" + "," + "500" + "," + tempValue.ToString());
                    }

                }
            }

<p>Sample input csv looks like this:</p>

<pre><code>id, datetime, msisdn, num, duration
33083,2011-12-19 05:17:57+06:30,98590149,1875,258
33084,2011-12-19 05:22:28+06:30,98590149,1875,69
33085,2011-12-19 05:23:45+06:30,98590149,1875,151
33086,2011-12-19 05:30:21+06:30,98590149,1875,58
33087,2011-12-19 06:44:19+06:30,949826259,1875,66
</code></pre>

<p>And I'd like to have my output like this:</p>

<pre><code>id, datetime, msisdn, num, duration, type, ammount, total
33083,2011-12-19 05:17:57+06:30,98590149,1875,258,1,500,500
33084,2011-12-19 05:22:28+06:30,98590149,1875,69,1,500,500
33085,2011-12-19 05:23:45+06:30,98590149,1875,151,1,500,500
33086,2011-12-19 05:30:21+06:30,98590149,1875,58,1,500,500
</code></pre>
