switch case in c#

when we have more than two conditional statement it always better to use switch case.
->compared to serise of "if else" statement better is switch case

sample code:

public class days

{

  days s= new days();

  string dayname= d.GetName(s);

  Response.Write("day name");

  }

}

public class days

{

  public string Getdaynames(int day)

  { 

    switch(days)

   {

    case1:

   return "mondays";

   case1:   return "mondays";

   case2:   return "tuesday";

   case3:   return "wednesday";

   case4:   return "thusday";

   case5:   return "fridays";

   case6:   return "saturedays";

   case7:   return "sundays";

}
