我有一个C＃应用程序，它引用另一个类来加载excel数据，如下所示：

这是Excel加载数据类：

public class LoadExcelDictionary
{
    private Log log = new Log();
    public List<ULTLData> Load(string Input,string OutputDirectory,BackgroundWorker BackgroundWorker)
    {
        List<ULTLData> output = new List<ULTLData>();
        try
        {

            var segmentFull = 0;
            XSSFWorkbook xssfWorkbook;
            using (FileStream file = new FileStream(@Input,FileMode.Open,Fileaccess.Read))
            {
                //hssfWorkbook = new HSSFWorkbook(file);
                xssfWorkbook = new XSSFWorkbook(file);
            }
            ISheet sheet = xssfWorkbook.GetSheet("Sheet1");
            DataFormatter df = new DataFormatter();
            for (int i = 0; i <= sheet.LastRowNum; i++)
            {
                segmentFull = (((i + 1) * 100) / sheet.LastRowNum);
                //0 is the header row
                if (i > 0)
                {
                    ULTLData uLTLData = new ULTLData
                    {
                        VV = df.FormatCellValue(sheet.GetRow(i).getcell(0)),};
                    output.Add(uLTLData);
                    Console.WriteLine("Loading Excel Data - " + uLTLData.VV);
                }
                BackgroundWorker.ReportProgress(segmentFull);
            }
        }
        catch (Exception e)
        {
            Console.WriteLine("Exception: " + e.Message);
            log.Output(e.Message + " " + e.Source);
        }
        return output;
    }
}

我从UI代码中引用Excel数据加载器，如下所示：

private void backgroundWorker_DoWork(object sender,DoWorkEventArgs e)
{
    var backgroundWorker = sender as BackgroundWorker;
    segmentFull = 0;
    LoadData ld = new LoadData();
    LoadExcelDictionary led = new LoadExcelDictionary();
    WriteFile wf = new WriteFile();
    try
    {
        var loadedExcel = led.Load(Dictionary,Output,backgroundWorker);
        setStatusLabel("Loading Excel Data Completed");
        log.Output("Loading Excel Data Completed");
    }
    catch (Exception exception)
    {
        Console.WriteLine("Exception: " + exception.Message);
        log.Output(exception.Message + " " + exception.Source);
    }
}

问题是当我在调试中运行它时，程序运行良好，并在LoadExcelDictionary返回数据后继续运行。在发布模式下，它什么都不做，并保留在此行：

  

var loadingExcel = led.Load（Dictionary，Output，backgroundWorker）;

我不确定该如何解决。

编辑：

我发现了问题所在。它与更新标签有关。我有使用的标签功能：

    private void setStatusLabel(string Input)
    {
        if (statusLB.InvokeRequired)
            statusLB.Invoke(new action(() => statusLB.Text = Input));
        else
            statusLB.Text = Input;
    }

这是我的应用程序突然停止的原因。这是动态更新标签的正确方法吗？
