c# - Accessing MainWindow from another window -

i have created new window opens mainwindow. upon clicking button window, window should close , @ same time trigger event in mainwindow.

i thought easy implement don't know how access mainwindow methods & fields window...

any appreciated. thanks! :)

that wrong way it... child window should have closed event can register handler for. if need execute parent window functions child before has closed can pass delegates in child when open it.
