Winform版本吗?

参考如下代码：

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:\_64.png");
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;
fpSpread1.Sheets[0].ColumnHeader.Rows[0].Height = 300;
fpSpread1.Sheets[0].ColumnHeader.Cells[0, 0].CellType = icelltype;
fpSpread1.Sheets[0].ColumnHeader.Cells[0, 0].Value = image;
