Question

用C#做Excel插件时总报错不包含“Application”的定义，是否缺少using指令或程序集引用，求大神告知why！

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Linq;
using Excel = Microsoft.Office.Interop.Excel;
using Office = Microsoft.Office.Core;
using Microsoft.Office.Tools.Excel;
using System.Data;
using System.Data.OleDb;
using System.Windows.Forms;
using System.Drawing;
using Microsoft.Office.Interop.Excel;
using System.Reflection;

Answer 1

你先new一个对象
Microsoft.Office.Interop.Excel.Application appapp = new Microsoft.Office.Interop.Excel.Application();

追问

添加了这一句还是同样的错误
