EXCEL中插入图片

在xlApp.Visible = true;之前插入以下代码

worksheet.Shapes.AddPicture("C:\\Users\\spring\\Desktop\\1.gif", Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoCTrue, 100, 200, 200, 300);

    worksheet.Shapes.AddTextEffect(Microsoft.Office.Core.MsoPresetTextEffect.msoTextEffect1, "123456", "Red", 15, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoTrue, 150, 200);
