需要在窗体增加imageList和listview控件，并把ListView控件的LargeImageList设置为imageList1
ListView控件显示图片的大小可以在imageList1控件中调整ImageSize属性，如果图片失真，可以设置imageList1控件的ColorDepth值为Depth32Bit.
窗体设计：

- EXCEL.Worksheet workSheet = eApp.ActiveSheet;
- try

- }
- catch (Exception ex)
- {
- MessageBox.Show(ex.Message);
- }
- finally

运行效果：
