使用C#在Excel上的特定单元格中添加图片

Question

我正在尝试将图像添加到第3行第1列的Excel单元格中,如下所示.编译器给了我一个错误.我在这里做错了吗？提前感谢您的建议.

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);

Answer 1

你必须添加如下图片

Microsoft.Office.Interop.Excel.Range oRange = (Microsoft.Office.Interop.Excel.Range)ws.Cells[3, 1];
float Left = (float)((double)oRange.Left);
float Top = (float)((double)oRange.Top);
const float ImageSize = 32;
ws.Shapes.AddPicture("C:\\pic.JPG", Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoCTrue, Left, Top, ImageSize, ImageSize);
