title: Excel GoalSeek algorithm
body: <p>Does anyone have the code for this algorithm ? Any C-based programming language would be OK but I prefer C#.</p>
  
  <p>I could try to implement it but I'm sure I'm not the first one... </p>
  
  <p><strong>edit:</strong> It's not homework, it's a "gimme teh codez" question :D I just don't want to reinvent the wheel</p>
