我正在尝试复制包含图表的工作表,但是当我尝试这样做时,我的代码会触发“源部分不存在具有指定 ID 的包关系”异常,这可能是什么原因?*如果我从模板中删除图表,一切正常。

这是我的代码:

  public void GenerateFromTemplate(DirectoryInfo outputPath, FileInfo templateFile,
        string newFileName, List<Dictionary<string, string>> cellDataList)
    {
        try
        {
            using (ExcelPackage p = new ExcelPackage(templateFile, true))
            {
                bool first = true;
                foreach (Dictionary<string, string> cellData in cellDataList) {
                    Logger.LogInfo("Adding new Sheet...");
                    ExcelWorksheet currentWorkSheet;
                    if (first)
                    {
                        currentWorkSheet = p.Workbook.Worksheets[1];
                        first = false;
                    }
                    else {
                        currentWorkSheet = p.Workbook.Worksheets.Copy("Ticker", "Ticker" + p.Workbook.Worksheets.Count);
                    }

                    foreach (KeyValuePair<string, string> cell in cellData)
                    {
                        Logger.LogInfo(cell.Key + "cell value set to" + cell.Value);
                        currentWorkSheet.Cells[cell.Key].Value = cell.Value;
                    }
                }
                Byte[] bin = p.GetAsByteArray();

                string file = outputPath + newFileName;
                Logger.LogInfo("Writing Excel File to " + file);
                File.WriteAllBytes(file, bin);
                Logger.LogInfo("Writing Done");
            }
        }
        catch (Exception ex)
        {
            Logger.LogError(ex);
        }
    }

问候!
