Code inspection: Convert 'if' statement into 'switch'

This inspection reports series of if statements and suggests converting them into a single switch statement or switch expression.

A single switch can make your code cleaner and easier to understand compared to multiple if statements, especially as the number of tested cases increases.

            
class Parser
{
  Marker Parse(string marker)
  {
    if (marker is "<=HEADER=>")
      return Marker.Header;

    if (marker is "<=FOOTER=>")
      return Marker.Footer;

    return Marker.None;
  }
}

enum Marker {None, Header, Footer}

        

            
class Parser
{
  Marker Parse(string marker)
  {
    return marker switch
    {
      "<=HEADER=>" => Marker.Header,
      "<=FOOTER=>" => Marker.Footer,
      _ => Marker.None
    };
  }
}

enum Marker {None, Header, Footer}
