C cannot convert method to non delegate type

Question

I have a class called Pin   public class Pin       private string title       public Pin            public setTitle string title            this title   title            public String getTitle                 return title            From another class I add Pins objects in a List lt Pin gt  pins and from another I want to iterate the List pins and get the elements  So I have this code   foreach  Pin obj in ClassListPin pins         string t   obj getTitle      With this code I cannot retrieve the title  Why     Note  ClassListPin is just a static class which contains some elements and one of these  is the List lt Pin gt  pins

getTitle is a function  so you need to put    after it     string t   obj getTitle

As  Antonijn stated  you need to execute getTitle method  by adding parentheses    string t   obj getTitle      But I want to add  that you are doing Java programming in C   There is concept of properties  pair of get and set methods   which should be used in such cases   public class Pin       private string  title          you don t need to define empty constructor        public Pin            public string Title                get   return  title            set    title   value                And even more  in this case you can ask compiler not only for get and set methods generation  but also for back storage generation  via auto-impelemented property usage   public class Pin       public string Title   get  set        And now you don t need to execute method  because properties used like fields   foreach  Pin obj in ClassListPin pins         string t   obj Title

As mentioned you need to use obj getTile    But  in this case I think you are looking to use a Property   public class Pin       private string title       public Pin            public setTitle string title            this title   title             public String Title               get   return title              This will allow you to use  foreach  Pin obj in ClassListPin pins         string t   obj Title

You need to add parentheses after a method call  else the compiler will think you re talking about the method itself  a delegate type   whereas you re actually talking about the return value of that method   string t   obj getTitle        Extra Non-Essential Information  Also  have a look at properties  That way you could use title as if it were a variable  while  internally  it works like a function  That way you don t have to write the functions getTitle   and setTitle string value   but you could do it like this   public string Title    Note  public fields  methods and properties use PascalCasing       get    This replaces your getTitle method               return  title     Where  title is a field somewhere           set    And this replaces your setTitle method                title   value     value behaves like a method parameter           Or you could use auto-implemented properties  which would use this by default   public string Title   get  set      And you wouldn t have to create your own backing field   title   the compiler would create it itself   Also  you can change access levels for property accessors  getters and setters    public string Title   get  private set      You use properties as if they were fields  i e    this Title    Example   string local   this Title

You can simplify your class code to this below  and it will work as is but if you want to make your example work  add parenthesis at the end    string x   getTitle     public class Pin      public string Title   get  set

Because getTitle is not a string  it returns a reference or delegate to a method  if you like   if you don t explicitly call the method   Call your method this way   string t  obj getTitle       obj getTitle    says return the title string object   However  this would work   Func lt string gt  method   obj getTitle     this compiles to a delegate and points to the method  string s   method     call the delegate or using this syntax  method Invoke

To execute a method you need to add parentheses  even if the method does not take arguments   So it should be   string t   obj getTitle
