将数据写入Excel工作表时，C＃应用程序终止

Question

我正在尝试使用.Net在excel工作表中写入数据。但是，由于某种原因，当行计数器增加到大约900时，整个应用程序终止（没有例外，没有警告，没有消息）。然而，最多可以有10000个条目。

此外，如果我在填充内容时输入睡眠声明，它也会终止。我怀疑excel对象存在某种超时？

任何想法可能导致这个？感谢

这是主要功能 -

    public void ProduceExcelReport(string reportDirPath, List<MedlineRecord> medlineRecords, List<AccessionRecord> accessionRecords,
        List<string> dataBanksOfInterest, bool overwrite)

            string fullReportPath = Path.Combine(reportDirPath, ReportName);

            if (File.Exists(fullReportPath))

                    fullReportPath));
            }

            // Initialise
            excelApp.DisplayAlerts = false;
            object misValue = System.Reflection.Missing.Value;

以下是填充工作表内容的功能之一

    private void FillMedlineParsingReportContents(ref Excell.Worksheet excelWorkSheet, List<MedlineRecord> medlineRecords, List<string> dataBanksOfInterest)
    {
        // Write the worksheet contents
        AddFirstRow(ref excelWorkSheet);
        excelWorkSheet.Name = "Medline XML Parsing Summary";
        excelWorkSheet.Cells[2, 6] = string.Format("Total articles: {0}", medlineRecords.Count);
        excelWorkSheet.Cells[3, 6] = string.Format("Total number dataBank list tags: {0}", (from element in medlineRecords 
                                                                                            where element.DataBanksDict.Count > 0
                                                                                            select element).Count());

                                                                                       select element.DataBanksDict.Count).Sum());

        int i = 2;
        foreach (MedlineRecord record in Utilities.FilterOutMedlineRecords(medlineRecords, dataBanksOfInterest))
        {
            foreach (AccessionRecord accessionRecord in record.GetAccessionRecords())
            {
                excelWorkSheet.Cells[i, 1] = accessionRecord.BankName;
                excelWorkSheet.Cells[i, 2] = accessionRecord.AccessionId;
                excelWorkSheet.Cells[i, 3] = accessionRecord.PMID;
                excelWorkSheet.Cells[i, 4] = accessionRecord.FileName;
                i++;

                // Terminates when I reaches around 800-900
                Console.WriteLine(i);
            }
        }
    }
