Question

我正在尝试阅读excel表中的评论，但无法这样做。请帮忙。提前致谢。我的代码如下 -

  Excel.Application appExl;
  Excel.Workbook workbook;
  Excel.Worksheet NwSheet;
  Excel.Range ShtRange;
  appExl = new Excel.Application();
  workbook = appExl.Workbooks.Open(Server.MapPath("~/" + System.Configuration.ConfigurationManager.AppSettings["ExcelFile"] + fileName), Missing.Value, Missing.Value,
  Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value,
  Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value);
  NwSheet = (Excel.Worksheet)workbook.Sheets.get_Item(1);
  string obj = NwSheet.Range[0].Comment.Text;

Answer 1

你基本上拥有它，但正如Wimbo所说，0不是有效范围。

当从.Net与Office进行交互时，数组总是从一开始。范围是一个2D数组，所以一旦你有一个范围，就可以这样访问该范围中的左上角单元格：

using Excel = Microsoft.office.Interop.Excel;
Excel.Range range = worksheet.Cells[1,1];

要访问左上角的单元格，您可以这样做：

Excel.Range range = worksheet.Cells[2,1]; //It goes row, then column

要访问左上角单元格右侧的单元格，请执行以下操作：

Excel.Range range = worksheet.Cells[1,2];

如果您在.Net 4或更高版本中工作，则无需指定可选参数（换句话说，您可以删除所有 Missing.Value ）。我猜你想在工作簿中的Sheet 1上的Cell A1中获得评论，我会这样做：

using System.Runtime.InteropServices;
using Excel = Microsoft.Office.Interop.Excel;

namespace ExcelComments
{
    class Program
    {
        static void Main()
        {
            var application = new Excel.Application();
            var workbook = application.Workbooks.Open(@"C:\Yada yada\workbook with comments.xlsx");
            Excel.Worksheet worksheet = workbook.Sheets[1];

            Excel.Range range = worksheet.Cells[1, 1];

            //Here is your comment as a string
            var myComment = range.Comment.Text();

            workbook.Close(false);
            application.Quit();

            Marshal.ReleaseComObject(application);
        }
    }
}
