这几天做向Excel插入数据,其中有插入图片的需求,经试验,下面2种方法都可以插入图片,但各有不同的用处。现将这2种方法共享出来, 希望需要的朋友进行参考,代码中已经有详细注释了。
注意:使用之前需要引用COM:Microsoft Office 11.0 Object Library
如果引用列表中没有,需要自行添加 C:/Program Files/Microsoft Office/OFFICE11/EXCEL.EXE
调用方法:
MengXianhui.Utility.ExcelReport.InsertPictureToExcel ipt
=
new
MengXianhui.Utility.ExcelReport.InsertPictureToExcel();
ipt.Open();
ipt.InsertPicture( " B2 " , @" C:/Excellogo.gif " );
ipt.InsertPicture( " B8 " , @" C:/Excellogo.gif " , 120 , 80 );
ipt.SaveFile( @" C:/ExcelTest.xls " );
ipt.Dispose();
ipt.Open();
ipt.InsertPicture( " B2 " , @" C:/Excellogo.gif " );
ipt.InsertPicture( " B8 " , @" C:/Excellogo.gif " , 120 , 80 );
ipt.SaveFile( @" C:/ExcelTest.xls " );
ipt.Dispose();
简单包装的类:
