我有一个从数据库表创建 Excel 文件的小程序，使用 Excel 2013 一切正常，但我现在需要它用于 Excel 2010，现在当我将“格式”添加到NumberFormatLocal (range.NumberFormatLocal = format;) 当我使用 range.NumberFormat = format;

异常(exception):

Error message: System.Runtime.InteropServices.COMException (0x80020005): Type Conflict. (Exception of HRESULT: 0x80020005 (DISP_E_TYPEMISMATCH)) At System.RuntimeType.ForwardCallToInvokeMember (String memberName, BindingFlags flags, ObjectTarget, Int32 [] aWrapperTypes, MessageData & msgData)

功能:

if (chkWithValues.Checked && results.Item3.Any())
            {
                var rows = results.Item3.Count;
                var cols = results.Item3.Max(x => x.Count);
                object[,] values = new object[rows, cols];
                object[,] format = new object[rows, cols];

                //All returned items are inserted into the Excel file
                //Item2 contains the database types, Item3 the Values
                // pgMain shows the progress for the selected tables
                for (int j = 0; j < results.Item3.Count(); j++)
                {
                    int tmpNbr = 1;
                    SetMessage($"{selectedTableItem.TableName} {j} von {results.Item3.Count}", LogHelper.NotificationType.Information);
                    foreach (string value in results.Item3[j])
                    {
                        values[j, tmpNbr - 1] = Converter.Convert(results.Item2[tmpNbr - 1], value).ToString().Replace("'", "");
                        format[j, tmpNbr - 1] = ExcelColumnTypes.ConvertToExcelTypes(results.Item2[tmpNbr - 1]);
                        tmpNbr++;
                    }
                    pgMain.Maximum = results.Item3.Count();
                    pgMain.PerformStep();
                }
                Excel.Range range = xlWorksheet.Range["A3", GetExcelColumnName(cols) + (rows + 2)];
                SetMessage($"{results.Item3.Count * results.Item1.Count} Zellen werden formatiert....", LogHelper.NotificationType.Information);

                range.NumberFormatLocal = format;
                range.Value = values;
            }

我的 Excel 类型:

public const string INT = "0";

    public const string TEXT = "@";
    public const string GENERAL = "General";
    public const string STANDARD = "Standard";

    public const string Date1 = "m/d/yyyy";
    public const string DATE2 = "TT.MM.JJJJ";
    public const string DATE3 = "T.M.JJ h:mm;@";
    public const string DATETIME = "d/m/yy h:mm;@";

    public const string DOUBLECO1 = "#.##0,00";
    public const string DOUBLECO2 = "0,00";

    public const string DOUBLEPO1 = "#0,##0.00";
    public const string DOUBLEPO2 = "0.00";

    public const string CUSTOM = "#,##000";

    public const string CURRENCYEU1 = "#,##0,00 _€";
    public const string CURRENCYEU2 = "#,##0 _€";
    public const string CURRENCYEU3 = "#,##0,00 €";

    public const string CURRENCYDO1 = "#,##0.00 _$";
    public const string CURRENCYDO2 = "#,##0 _$";
    public const string CURRENCYDO3 = "#,##0.00 $";

    public const string PERCENTAGE1 = "0.00%";
    public const string PERCENTAGE2 = "0.0%";
    public const string PERCENTAGE3 = "0%";

更新:

我已经尝试使用 public const string TEXT = "@"; 作为唯一的格式，但出现了同样的错误

更新 2:

只有当表格有很多条目时才会发生错误。例如，当我使用一个包含 1000 个条目的表时，没问题并且一切正常，如果我使用一个包含 200.000 个条目的表，则会发生错误

更新 3:

我试过只使用标准格式进行测试，出现如下错误:

Error message: System.OutOfMemoryException: Insufficient memory available to continue the program.

最佳答案

是否可能是您向 Excel 传递的内容被解释为对于 Excel 2010 中的整数数据类型而言太大的整数？ 例如行号？通过加载 32,760 行然后加载 32,770 行来测试它，因为整数在 XL 2010 中最多只能达到 32,767。值得一试 :o)
