Some basic thinking regarding flow of code. To create or not to create new variables
<p>I'm a beginner c# programmer and I'm curious which of the variants from bellow it's better from the point of view of the compiler and so on.</p>

<p>Variant 1</p>

<pre><code>string file = "20071201.22002300.wmv"; //name of the file is YYYYMMDD.HHMMHHMM.wmv
string[] tmp= file.Split('.');
DateTime startDate= new DateTime(Convert.ToInt32(tmp[0].Substring(0, 4)),
                                 Convert.ToInt32(tmp[0].Substring(4, 2)), 
                                 Convert.ToInt32(tmp[0].Substring(6, 2)), 
                                 Convert.ToInt32(tmp[1].Substring(0, 2)), 
                                 Convert.ToInt32(tmp[1].Substring(2, 2)), 0);

DateTime endDate =new DateTime(Convert.ToInt32(tmp[0].Substring(0, 4)), 
                               Convert.ToInt32(tmp[0].Substring(4, 2)), 
                               Convert.ToInt32(tmp[0].Substring(6, 2)), 
                               Convert.ToInt32(tmp[1].Substring(4, 2)),
                               Convert.ToInt32(tmp[1].Substring(6, 2)), 0);
</code></pre>

<p>Variant 2</p>

<pre><code>string file = "20071201.22002300.wmv"; //name of the file is YYYYMMDD.HHMMHHMM.wmv
string[] tmp= file.Split('.');
int year = Convert.ToInt32(tmp[0].Substring(0, 4));
int month= Convert.ToInt32(tmp[0].Substring(4, 2));
int day = Convert.ToInt32(tmp[0].Substring(6, 2));
int hour = Convert.ToInt32(tmp[1].Substring(0, 2));
int minute = Convert.ToInt32(tmp[1].Substring(2, 2));
int endHour= Convert.ToInt32(tmp[1].Substring(4, 2));
int endMinute = Convert.ToInt32(tmp[1].Substring(6, 2));
DateTime startDate= new DateTime(year, month, day, hour, minute, 0);
DateTime startDate= new DateTime(year, month, day, endHour, endMinute, 0);
</code></pre>

<p>Generally i prefer to work as in first variant because i'm not working as a programmer so i don't work together with other programmers, I'm just creating tools to help in my job , and also i consider that the first variant it's easier for the compiler.</p>

<p>Please correct if i'm wrong and thanks in advance</p>
