要将单元格数据类型设置为ImageCellType
- FarPoint.Win.Spread.CellType.ImageCellType icelltype = new FarPoint.Win.Spread.CellType.ImageCellType();
- icelltype.Style = FarPoint.Win.RenderStyle.Stretch;
- icelltype.TransparencyColor = Color.Black;
- icelltype.TransparencyTolerance = 100;
- fpSpread1.Sheets[0].Rows[0].CellType = icelltype;
- System.Drawing.Image image = System.Drawing.Image.FromFile("D:\\alphaomega3.jpg");
- System.IO.MemoryStream stream = new System.IO.MemoryStream();
- byte[] bytes;
- string str;
- image.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);
- stream.Seek(0, System.IO.SeekOrigin.Begin);
- bytes = stream.GetBuffer();
- str = System.Convert.ToBase64String(bytes);
- fpSpread1.Sheets[0].Cells[0, 0].Value = image;
- fpSpread1.Sheets[0].Cells[0, 1].Value = bytes;
- fpSpread1.Sheets[0].Cells[0, 2].Value = str;
