Question

显示进度条值时出现问题。我想，进度条使用其他线程来更新他的值，但它只在ParseTpSheet方法之后才能实现。我希望，你会帮助我。感谢。

        ParseProgressBar.Value = e.ProgressPercentage;
    }

    private void IncProgressBar(int value)
    {
        ParseProgressBar.Value += value;
    }

    private void AddFileButton_OnClick(object sender, RoutedEventArgs e)

        var excelApplication = new Excel.Application();
        var openFileDialog = new OpenFileDialog {Filter = "excel files(*.xls)(*.xlsx)|*.xls;*.xlsx" };
        openFileDialog.ShowDialog();
        if (openFileDialog.FileName.EndsWith(".xls") || openFileDialog.FileName.EndsWith(".xlsx"))
        {
            ParseProgressBar.Value = 0;
            worker.RunWorkerAsync();
            _parserModel.Workbook = excelApplication.Workbooks.Add(openFileDialog.FileName);
            _parserModel.ParseTpSheet();
        }
        else
        {
            MessageBox.Show("Файл не был выбран", "Уведомление", MessageBoxButton.OK, MessageBoxImage.Information);
        }
        excelApplication.Quit();
    }
  }
}
