You re currently trying to access a method like a property Console WriteLine  quot  0  quot  x fullNameMethod    It should be Console WriteLine  quot  0  quot  x fullNameMethod      Alternatively you could turn it into a property using public string fullName      get              string x   firstName    quot   quot    lastName          return x

You don t have to have a method for that  You could create a property like this instead  class SalesPerson       string firstName  lastName      public string FirstName   get   return firstName    set   firstName   value          public string LastName   get   return lastName    set   lastName   value          public string FullName   get   return this FirstName    quot   quot    this LastName         The class could even be shortened to  class SalesPerson       public string FirstName   get  set        public string LastName   get  set        public string FullName           get   return this FirstName    quot   quot    this LastName              The property could then be accessed like any other property  class Program       static void Main string   args                SalesPerson x   new SalesPerson  quot John quot    quot Doe quot            Console WriteLine x FullName      Will print John Doe

You forgot the    at the end  It is not a variable  but a function and when there are not parameters  you still need the    at the end  For future coding practices  I would highly recommend reforming the code a little bit as this can become frustrating to read   public string LastName    get   return lastName    set   lastName   value       If there is any kind of processing which happens in here  thankfully doesn t happen here   it will become very confusing  If you re going to pass your code onto someone else  I would recommend  public string LastName     get          return lastName        set          lastName   value         It s a lot longer  but it s much easier to read when glancing at a huge section of code

These answers are all way too complicated  The way he wrote the method is fine  The problem is where he invoked the method  He did not include parentheses after the method name  so the compiler thought he was trying to get a value from a variable instead of a method  In Visual Basic and Delphi  those parentheses are optional  but in C   they are required  So  to correct the last line of the original post  Console WriteLine  quot  0  quot   x fullNameMethod
