Здравствуйте! Не могу разобраться как работать с thread в windows forms. Пишу в visual studio 2015. Идея в том что бы по нажатию на 2 разные кнопки запускались 2 разных потока и выводили значения в соответствующий listbox с определенными задержками, а по нажатию на 3-ю кнопку в 3-й listbox я в ручную выводил цифры. | Код |
