我正尝试将图像添加到Excel单元格的第3行第1列，如下所示.编译器给我一个错误.我在这里做错了吗?预先感谢您的建议. Excel.Application xlApp; Excel.Workbook wb; Excel.Worksheet ws;目的 misValue = System.Reflection.Missing.Value; xlApp =新的Excel.Application(); wb = xlApp.Workbooks.Add(misValue); ws =(Excel.Worksheet)wb.Worksheets.get_Item(1); ws.Cells [3，1] = ws.Shapes.AddPicture("C:\\ photos \\ 4a.png"，Microsoft.Office.Core.MsoTriState.msoFalse， Microsoft.Office.Core.MsoTriState.msoCTrue，75，75，350，50);

I am trying to add an image into Excel cell at row 3 column 1 as specified below. The compiler gave me an error. Did I do something wrong here? Thanks in advance for your suggestions. Excel.Application xlApp; Excel.Workbook wb; Excel.Worksheet ws; object misValue = System.Reflection.Missing.Value; xlApp = new Excel.Application(); wb = xlApp.Workbooks.Add(misValue); ws = (Excel.Worksheet)wb.Worksheets.get_Item(1); ws.Cells[3, 1] = ws.Shapes.AddPicture("C:\\photos\\4a.png", Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoCTrue, 75, 75, 350, 50);
