推荐答案

如果您正在谈论WinForms，最简单的方法是OLEDB.难于使用Excel互操作.要修改excel工作表的外观，最好使用excel interop.

If you are talking about WinForms,the easiest way is OLEDB.The harder is Excel interop.If you are to modify visuals of excel sheets, excel interop is preferable.

如果您能写出excel互操作失败的位置/方式，我可以帮忙吗?

I can help if you can write where/how excel interop failed?

您使用Excel Interopt，还不错.以下是如何创建Excel文件的示例:

You use Excel Interopt, which is not too bad. Here is an example of how to create an Excel file:

private static void Excel(string fileName, List<IDirectoryInventoryDataCollector> list)
{
    try
    {
        var xlApp = new Excel.Application();
        var xlWorkBook = xlApp.Workbooks.Add();
        var xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
        ExcelTitleRow(list[0], 1, xlWorkSheet);

        int row = 2;
        foreach (var item in list)
        {
            ExcelFillRow(item, row++, xlWorkSheet);
        }

        for (int i = 1; i < list[0].MaxLevel - 1; i++)
        {
            ((Range)xlWorkSheet.Columns[i]).ColumnWidth = 2;
        }
        ((Range)xlWorkSheet.Columns[list[0].MaxLevel - 1]).ColumnWidth = 30;
        ((Range)xlWorkSheet.Rows[1]).WrapText = true;
        ((Range)xlWorkSheet.Rows[1]).HorizontalAlignment = HorizontalAlignment.Center;
        ((Range)xlWorkSheet.Cells[1, 1]).WrapText = false;

        xlWorkBook.SaveAs(fileName);
        xlWorkBook.Close();
        xlApp.Quit();
    }
    catch (AccessViolationException)
    {
        System.Windows.Forms.MessageBox.Show(
             "Have encountered access violation. This could be issue with Excel 2000 if that is only version installed on computer",
             "Access Violation");
    }
    catch (Exception)
    {
        System.Windows.Forms.MessageBox.Show("Unknown error",
             "Unknown error");
    }
}

private static void ExcelFillRow(IDirectoryInventoryDataCollector item, int row, Excel.Worksheet sheet)
{
    sheet.Cells[row, item.Level] = item.Name;
    int column = item.MaxLevel;
    foreach (var property in item.GetProperties())
    {
        sheet.Cells[row, column++] = property;
    }
}

private static void ExcelTitleRow(IDirectoryInventoryDataCollector item, int row, Excel.Worksheet sheet)
{
    sheet.Cells[row, 1] = "Name";
    int column = item.MaxLevel;
    foreach (var property in item.GetPropertyNames())
    {
        sheet.Cells[row, column++] = property;
    }
}
