c# - how to stop old event when new event is occurs -

i have 2 button click events.

void button1_click(...) {     //do somethings     foo(); }  void button2_click(...) {     //do somethings     foo(); } 

the function foo() take more 1 minutes finished.

when click on button1, , after click button2. how can stop foo() in button1_click , run foo() on button2_click?

you should run foo on separate thread, , invoke update on ui thread once complete use cancelation token stop given operation @ time. similar post here how update gui thread in c#?
