String concatenation based on best practices
<p>I have a string,</p>

<pre><code>string ij = "/alwaysSame09102012/myThing.aspx?asdasd=99&amp;Urasdl=scashdasdeasdmeasds/tasdigaesdr1/gasdoasdveasdasdrnaasdancasde/eamsdeasdetiasdasdnagsds/tasidgeasdr1masdeetasdasd11180,/reasdMeasdetMe2as0d1asd0/asrdganasdiseasdasdgeasdetasdiasdngaasdsd.aasdspafsxasdffas?asdsdlaieasdnedtfe=asdsafaser1meafswedfhfdget111ertert80"
</code></pre>

<p>Now i just need to change the first "alwaysSame09102012" with "always2013forever".</p>

<p>I know i can do something like this,</p>

<pre><code>string ij = "/alwaysSame09102012/myThing.aspx?asdasd=99&amp;Urasdl=scashdasdeasdmeasds/tasdigaesdr1/gasdoasdveasdasdrnaasdancasde/eamsdeasdetiasdasdnagsds/tasidgeasdr1masdeetasdasd11180,/reasdMeasdetMe2as0d1asd0/asrdganasdiseasdasdgeasdetasdiasdngaasdsd.aasdspafsxasdffas?asdsdlaieasdnedtfe=asdsafaser1meafswedfhfdget111ertert80"

string[] c = ij.split['/'];

string finalString =  ij.replace( "/" + c[0] + "/", "/" + "always2013forever" + "/");
</code></pre>

<p>This is my logic but no working, please help,</p>

<p>only constant in my string is  <code>"/alwaysSame09102012/"</code> which i need to replace</p>

<p><strong>Update</strong></p>

<p>**</p>

<ul>
<li><em>What if I got this "alwaysSame09102012"  in at of my query string,
that's why I don't want to use replace.</em></li>
</ul>

<p>**</p>
