How to concat string to List C#
<p>I was trying to add the strings to the List and export the list as csv file but the result I got is not the way I want. Here is the code -</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 (tempValInt % 60 != 0)
        {
            tempMinInt = (tempValInt / 60) + 1;
            tempValue = tempMinInt * 30;
        }
        else
        {
            tempMinInt = tempValInt / 60;
            tempValue = tempMinInt * 30;
        }


        values.Add(lineValues + "," + tempValue.ToString());

    }
}

<p>Here is the sample input data: </p>

<pre><code>33083,2011-12-19 05:17:57+06:30,98590149,1876,258
33084,2011-12-19 05:22:28+06:30,98590149,1876,69
33085,2011-12-19 05:23:45+06:30,98590149,1876,151
33086,2011-12-19 05:30:21+06:30,98590149,1876,58
33087,2011-12-19 06:44:19+06:30,949826259,1876,66
</code></pre>

<p>And here is the output data:</p>

<pre><code>System.Collections.Generic.List`1[System.String],150
System.Collections.Generic.List`1[System.String],60
System.Collections.Generic.List`1[System.String],90
System.Collections.Generic.List`1[System.String],30
System.Collections.Generic.List`1[System.String],60
</code></pre>

<p>Please advice. Thank you.</p>
