如何在C＃中使用NPOI Excel添加单元格注释？

我想在C＃中使用NPOI Excel创build单元格注释。 我没有find任何明确的文件。 我自己写下如下。

NPOI.HSSF.Record.NoteRecord nr = new NPOI.HSSF.Record.NoteRecord(); nr.Author = "Some Author"; NPOI.HSSF.Record.TextObjectRecord tor = new NPOI.HSSF.Record.TextObjectRecord(); tor.Str = new HSSFRichTextString("something"); HSSFComment cm = new HSSFComment(nr, tor); cm.Visible = true; sheet.GetRow(i).Cells[k + 8].CellComment = cm; 

该代码无法正常工作。 在生成的excel文件中，我看不到有关该单元格的任何评论。 有没有人知道如何在特定的单元格中添加注释？

您需要使用绘图族长来创build单元格注释。 然后你可以定义你的作者和文字。 您也可以应用一些字体自定义。

请试试这个代码，我评论了不同的步骤：

 HSSFWorkbook workbook = new HSSFWorkbook(); HSSFSheet sheet = (HSSFSheet)workbook.CreateSheet("Sheet1"); HSSFRow row = (HSSFRow)sheet.CreateRow(0); HSSFCell cell = (HSSFCell)row.CreateCell(0); cell.SetCellValue("Cell1"); // Create the drawing patriarch (top level container for all shapes including cell comments) IDrawing patriarch = (HSSFPatriarch)sheet.CreateDrawingPatriarch(); // Client anchor defines size and position of the comment in the worksheet IComment comment = patriarch.CreateCellComment(new HSSFClientAnchor(0, 0, 0, 0, 2, 1, 4, 4)); // Set comment author comment.Author = "Author"; // Set text in the comment comment.String = new HSSFRichTextString($"{comment.Author}:{Environment.NewLine}A comment"); // If you want the author displayed in bold on top like in Excel // The author will be displayed in the status bar when on mouse over the commented cell IFont font = workbook.CreateFont(); font.Boldweight = (short)FontBoldWeight.Bold; comment.String.ApplyFont(0, comment.Author.Length, font); // Set comment visible comment.Visible = true; // Assign comment to a cell cell.CellComment = comment; using (MemoryStream exportData = new MemoryStream()) { workbook.Write(exportData); Response.ContentEncoding = Encoding.UTF8; Response.Charset = Encoding.UTF8.EncodingName; Response.ContentType = "application/vnd.ms-excel"; Response.AddHeader("content-disposition", $"attachment; filename=test.xls"); Response.Clear(); Response.BinaryWrite(exportData.GetBuffer()); Response.End(); }
