POI在导出的EXCEL中嵌入图片

string filename = ComMethod.ObjToString(Table1.Rows[index]["files"]);

if (!string.IsNullOrEmpty(filename))

{

string path = Server.MapPath(ConfigurationManager.AppSettings["ArtworkFile"]);

string readpath = path + filename;

FileInfo file = new System.IO.FileInfo(readpath);

if (!file.Exists)

{

ClientScript.RegisterStartupScript(Page.GetType(), "", "<script>alert('" + readpath + ",该文档不存在！');</script>");

}

byte[] bytes = System.IO.File.ReadAllBytes(readpath); //byte[] bytes = System.IO.File.ReadAllBytes("E:\\ttt\\Chrysanthemum.jpg"); int pictureIdx = hssfworkbook.AddPicture(bytes, PictureType.JPEG);

// Create the drawing patriarch. This is the top level container for all shapes. HSSFPatriarch patriarch = (HSSFPatriarch)excelSheet.CreateDrawingPatriarch();

//add a picture，hssfclientanchor包含8个参数，其中，后面四个参数分别指嵌入图片的位置 HSSFClientAnchor anchor = new HSSFClientAnchor(0, 0, 1023, 0, (short)(2 + tablesize.Rows.Count), 5, 11, (short)(startrow + deletecount1));

patriarch.CreatePicture(anchor, pictureIdx); }
