Question

我为复印表编写了 c# 程序。当我调用 WorkSheet.Copy方法直到105次。 这是我的代码片段：使用 Microsoft.Office.Interop.Excel；

private void CreateSheet(string dst_fileName)
{
    object cell1 = "A2";

    ApplicationClass app = null;
    Workbook book = null;
    Worksheet sheet = null;
    Worksheet sheet_to_copy = null;
    int i=0;

    try
    {
        app = new ApplicationClass();
        app.Visible = false;
        app.ScreenUpdating = false;
        app.DisplayAlerts = false;

        book = app.Workbooks.Open(dst_fileName, 0, false, 5, "", "", true,
                                  XlPlatform.xlWindows,
                                  "\t", false, false, 0, true, 1, 0);

        // Reference to the worksheet
        sheet_to_copy = (Worksheet)book.Worksheets[1];

        for(;i<listViewPrg.Items.Count;i++)
        {
            sheet = (Worksheet)book.Worksheets[book.Worksheets.Count];
            // Copy the worksheet to the end of the worksheets
            sheet_to_copy.Copy(Missing.Value, sheet);
            sheet.Name = "NewSheet(" + book.Worksheets.Count + ")";
        }
        book.SaveAs(dst_fileName, Missing.Value, Missing.Value, Missing.Value,
                    Missing.Value, Missing.Value, XlSaveAsAccessMode.xlNoChange, Missing.Value,
                    Missing.Value, Missing.Value, Missing.Value, Missing.Value);

    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }
    finally
    {
        QuitExcel(app);
    }
}

我找不到任何解决方案。有人可以给我一个提示来解决这个问题吗？ 太感谢了。

可能您有一些损坏的 Excel 注册表项之类的？

为什么不尝试使用 Excel 文件的开源阅读器并使用它们完成所有操作呢？速度会飙升，我保证你不会遇到这些错误！
