How to run Multiple Process in C# -

-
seniors, beginner , new in c# after php. my question how execute multiple function same time in c# e.g class void main() { call functiona(argument) call functionb(argument) call functionc(argument) // these function should start @ same time } my first function public void functiona(argument) { richtextbox1.appendtext(starttime); } my second function public void functionb(argument) { richtextbox1.appendtext(starttime); } my third function public void functionc(argument) { richtextbox1.appendtext(starttime); } your / guideline save time. the easiest option use task class. msdn nails it, copying (with minor edits) relevant bit here action action1 = () => { // code here }; action action2 = () => { // code here }; task t1 = new task(action1); task t2 = new task(action2); t1.start(); t2.start();
