[C# .NET] BackgroundWorker, ProgressBar 활용

[BackgroundWorker]

BackgroundWorker는 별도의 쓰레드에게 일을 시키기 위해 사용하는 클래스.

[ProgressBar]

ProgressBar는 작업진행이 얼마 되었는지 보여주는 표시바이다.

        public frmAutoGetList()

        {

            InitializeComponent();

            bworker.WorkerReportsProgress = true;

            bworker.WorkerSupportsCancellation = true;

            bworker.DoWork += new DoWorkEventHandler(bworker_DoWork);

            bworker.ProgressChanged += new ProgressChangedEventHandler(bworker_ProgressChanged);

            bworker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bworker_RunWorkerCompleted); 

        }

        //실행버튼

        private void cmdEx_Click(object sender, EventArgs e)

        {

            bworker.RunWorkerAsync();

        }

        //취소버튼

        private void cmdCancel_Click(object sender, EventArgs e)

        {

            bworker.CancelAsync();

            this.Close();

        }

        //백그라운드 실제 처리할 작업

        private void bworker_DoWork(object sender, DoWorkEventArgs e)

        {

            //백그라운드로 처리 할 코드 기입

            //bworker.ReportProgress(숫자);

        }

        //작업 진행률 표시

        private void bworker_ProgressChanged(object sender, ProgressChangedEventArgs e)

        {

            pBar.Value = e.ProgressPercentage;

        }

        //작업이 완료

        private void bworker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)

        {

            if (e.Error != null)

            {

                MessageBox.Show(e.Error.Message, "Error");

                return;

            }

        }
