Question

我必须将datagridview提取到Excel文件中。进入Excel，我有很多数据，例如当前日期。我按照range.Cells.NumberFormat = "General";的说明选择了单元格格式，但是如果我的当前日期的天数小于或等于12，则将月份和日期颠倒。

我的日期格式是dd / mm / yyyy，如果我有当前日期，例如25/08/2018，没有问题，但是如果我有一个日期，例如04/09/2018，则进入单元格，我有09 / 04/2018。

这是我完成的代码

private void CreateExcel(string _FileName, ArrayList header, ArrayList recordColl, int codLoanPosition)
    {
        ApplicationClass xlsApplication = null;
        Worksheet xlsWks = null;
        CultureInfo originalCultureInfo = null;
        Workbook currentWorkbook = null;
        Range range = null;

        string currentRow = "";
        string codLoan = "";
        bool primaRiga = true;
        try
        {
            log.Info("creazione oggetto CultureInfo ");

            originalCultureInfo = Thread.CurrentThread.CurrentCulture;
            Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");

            log.Info("creazione oggetto excel ");

            xlsApplication = new ApplicationClass();
            xlsApplication.Visible = false;

            log.Info("apertura file csv ");

            currentWorkbook = xlsApplication.Workbooks.Open(_FileName + ".csv", Type.Missing, Type.Missing, Type.Missing,
                                        Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
                                        Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

            xlsWks = (Worksheet)currentWorkbook.ActiveSheet;

            System.Drawing.Color interiorColor = System.Drawing.Color.FromArgb(153, 204, 255);
            //System.Drawing.Color interiorColorRow = System.Drawing.Color.FromArgb(195, 195, 195);

            log.Info("Create Excel range");

            range = xlsWks.get_Range(xlsWks.Cells[1, 1], xlsWks.Cells[1, header.Count]);
            range.Cells.NumberFormat = "General";
            range.Interior.Color = System.Drawing.ColorTranslator.ToOle(interiorColor);
            range.Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Black);
            range.Font.Size = 12;
            range.Font.Bold = true;
            range.RowHeight = 30;
            xlsWks.Cells.Columns.AutoFit();

            log.Info("salvataggio excel ");

            //Salva il file
            currentWorkbook.SaveAs(_FileName, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, Type.Missing, Type.Missing,
                                         Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,
                                         Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

            log.Info("completamento salvataggio excel ");
        }
        catch (Exception e)
        {
            //
            log.Info("Eccezione in conversione in xls: " + e.Message);
        }
        finally
        {
            currentWorkbook.Close(false, Type.Missing, Type.Missing);

            if (xlsApplication.Workbooks.Count == 0)
                xlsApplication.Quit();
            Thread.CurrentThread.CurrentCulture = originalCultureInfo;
            GC.Collect();
        }

我已经调试了我的代码，它执行了更改格式的指令。当我提取Excel文件时，所有单元格都是通用格式，但日期具有上面我告诉过你的特征。

我怎么做错了？

编辑：我没有以正确的方式解决我的问题，但是它可以正常工作。我为包含日期值的单元格创建了另一个范围，并使用此指令rangeDate.EntireColumn.NumberFormat = "mm/dd/yyyy";

设置了格式

我不知道它为什么起作用，但是通过这种方式，我的日期和月份处于正确的位置。如果找到最佳解决方案，我将再次编辑这篇文章
