C#向Excel報表中插入圖片的2種方法

這幾天做向Excel插入資料，其中有插入圖片的需求，經實驗，下面2種方法都可以插入圖片，但各有不同的用處。現將這2種方法共用出來， 希望需要的朋友進行參考，代碼中已經有詳細注釋了。

注意：使用之前需要引用COM：Microsoft Office 11.0 Object Library 如果引用列表中沒有，需要自行添加 C:\Program Files\Microsoft Office\OFFICE11\EXCEL.EXE

調用方法：

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();
簡單封裝的類：
