C# interview questions

Q)What’s the implicit name of the parameter that gets passed into the class’ set method?
Q)How do you inherit from a class in C#?
Q)Does C# support multiple inheritance?

Q)How’s anchoring different from docking?

 Ans:   Anchoring treats the component as having the absolute size and adjusts its location relative to the parent form. Docking treats the component location as absolute and disregards the component size. So if a status bar must always be at the bottom no matter what, use docking. If a button should be on the top right, but change its position with the form being resized, use anchoring.

Q)How do you create a separator in the Menu Designer?

 ANS)A hyphen ‘-’ would do it. Also, an ampersand ‘&\’ would underline the next letter.


Q)How would you create a non-rectangular window, let’s say an ellipse?

ANS)Create a rectangular form, set the TransparencyKey property to the same value as BackColor, which will effectively make the background of the form transparent. Then set the FormBorderStyle to FormBorderStyle.None, which will remove the contour and contents of the form.
