Is it possible to insert a string without using Console.WriteLine directly? : <p>for exemple: </p>

<pre><code>    while (!incomingFiles.EndOfStream)
   {
        sLine = incomingFiles.ReadLine();
        sLine.Insert(iCharacterIndicator , "something");
        Console.WriteLine(sLine);
   }
</code></pre>

<p>I want to put a desired string at a specific spot using an indexOf pointing where I need to put my 
desired string, so i'm using the iCharacterIndicator to point out each new lines where I need to put my string, but the Insert wont show on my console except when I insert directly in a Console.WriteLine, thus, ruining my algorithm.</p>
