OpenXML：Excel，提取单元格文本和图像/图片数据

我正在编写代码，将单元格中的单元格和图片/图像从Excel文档中提取到数据库中。

有了这个代码，我可以得到不是图片的单元格值。

但是，Cell对象没有图片。请注意，每一行都以图片开始。

A1- Picture B1- Text C1- Text and so on. 

如何从“A”列中获取图像？

  WorkbookPart wbPart = document.WorkbookPart; var workSheet = wbPart.WorksheetParts.FirstOrDefault(); foreach (Row r in workSheet.Worksheet.Descendants<Row>()) { //Note only has Colum B,C. Not A as A has an image??? foreach(Cell c in r.ChildElements) { foreach(object o in c.ChildElements) { Console.WriteLine(c.CellReference + " " + o.ToString()); } } }

  [Test] public void IterateThruImages() { WorkbookPart wbPart = document.WorkbookPart; var workSheet = wbPart.WorksheetParts.FirstOrDefault(); foreach (ImagePart i in workSheet.DrawingsPart.ImageParts) { var rId = workSheet.DrawingsPart.GetIdOfPart(i); Stream stream = i.GetStream(); long length = stream.Length; byte[] byteStream = new byte[length]; stream.Read(byteStream, 0, (int)length); var imageAsString = Convert.ToBase64String(byteStream); Console.WriteLine("The rId of this Image is '{0}'",rId); } } [Test] public void GetImageRelationshipIdAndImageOfThatId() { string row = "1"; string col = "0"; WorkbookPart wbPart = document.WorkbookPart; var workSheet = wbPart.WorksheetParts.FirstOrDefault(); TwoCellAnchor cellHoldingPicture = workSheet.DrawingsPart.WorksheetDrawing.OfType<TwoCellAnchor>() .Where(c => c.FromMarker.RowId.Text == row && c.FromMarker.ColumnId.Text == col).FirstOrDefault(); var picture = cellHoldingPicture.OfType<DocumentFormat.OpenXml.Drawing.Spreadsheet.Picture>().FirstOrDefault(); string rIdofPicture = picture.BlipFill.Blip.Embed; Console.WriteLine("The rID of this Anchor's [{0},{1}] Picture is '{2}'" ,row,col, rIdofPicture); ImagePart imageInThisCell = (ImagePart)workSheet.DrawingsPart.GetPartById(rIdofPicture); }
