Interface in C#

Question

please someone help me to do the buttons(code)of an interface in c# such as close, enlarge button, …

Answer 1

please explain yourself a bit more. What do you need to do ?

interface Button
{
void action(); // interface method (does not have a body)
}

Are you looking for something like this. Now the close button can implement is closing action in the action method and the enlarge button can implement a enlarging action in the action method.

Where is the size, color, text of the button defined ?

I can help. But one question a the time and one step a the time. You cannot make a super mathematical c# application in a day.

First question Winform or WPF ?

Google translation works ok. I do not understand french.
