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<Pin>
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<Pin>
pins)
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;
getTitle
is a function, so you need to put ()
after it.
string t = obj.getTitle();
