Thread.Sleep() 메서드를 사용할 때까지 백그라운드 작업자를 사용하여 내 UI가 여전히 차단됩니다. 하지만 50.000 이상의 단계를 거치면 프로그램이 매우 느려질 것입니다.Backgroundworker blocked UI

나는 그것이 Application.DoEvents와 시도() : 여기
는 do_work 방법입니다. 하지만 유일한 방법은 Thred.Sleep()입니다.
너무 많은 코드입니다. 백그라운드에서 UI에 액세스하고 있습니까? – user3185569
'worker.ReportProgress (1, new_emoticons.Count());'를 제거하고 다시 시도하십시오. 아직도 얼어 붙은거야? –
