c# - In Visual Studio Immediate window, why do I get Equals/GetHashCode/GetType/ToString as IntelliSense options for Button object? -

i in click() method button, , sender button object. want access actualwidth fellow member of said button, when type "sender." intellisense options, following:

1) these options, , 2) why don't following, expecting?

3) how can access actualwidth through sender in debugger?

edit:

in immediate window, casting sender button not help:

it because accessing button object in event, received object.

private void button1_click(object sender, eventargs e) //^^^^^^^^^^^^ { }

these methods (equals, gethashcode, tostring, gettype) available object class, , why seeing these.

see: object class (c# - msdn)

because classes in .net framework derived object, every method defined in object class available in objects in system.

(also see: not derives object - eric lippert)

to utilize object button have cast button object like:

private void button1_click(object sender, eventargs e) { button button = sender button; if (button != null) { //use properties } }

for immediate window:

you not using () while casting it, cast like:

((button)sender).
