作者:Dezai.CN / 发布于2013/1/4/ 536
将有绝对路径的图片导入excel
使用方法： 
 //string filename = "c://" + DateTime.Now.ToString("yyyyMMddhhmmss") + ".bmp"; 
 InsertPictureToExcel ipt = new InsertPictureToExcel();
 ipt.Open();
 ipt.InsertPicture("B2", @"c://20110907113220.bmp");
 ipt.InsertPicture("B8",filename, 120, 80);
 ipt.SaveFile(@"C:\"+ DateTime.Now.ToString("yyyyMMddhhmmss") +".xls");
 ipt.Dispose();
