private bool CheckAll         if                       return true             return false      When the if-condition is false the method doesn t know what value should be returned  you probably get an error like  not all paths return a value     As CQQL pointed out if you mean to return true when your if-condition is true you could have simply written   private bool CheckAll         return  your condition       If you have side effects  and you want to handle them before you return  the first  long  version would be required

You are missing the else portion  If all the conditions are false then else will work where you haven t declared and returned anything from else branch   private bool CheckALl       if condition          return true       else         return false

I m sure neither of these options were available in C  when you asked the question but nowadays you can do it like the following     Return with ternary conditional operator  private bool CheckAll         return  your condition    true   false        Alternatively as an expression bodied method  private bool CheckAll     gt   your condition    true   false

Long version   private bool booleanMethod          if  your condition            return true        else           return false            But since you are using the outcome of your condition as the result of the method you can shorten it to  private bool booleanMethod          return your condition

Use this code   public bool roomSelected         foreach  RadioButton rb in GroupBox1 Controls                if  rb Checked    true                        return true                      return false

A simpler way to explain this  public bool CheckInputs int a  int b   public bool condition   true   if  a  gt  b    a    b       condition   false    else      condition   true     return condition
