这几天没事在网上闲逛的时候看到类似的代码，花了点时间测试了一下。觉得不错。简单的整理一下。
在项目中需要引用：COM：Microsoft Office 11.0 Object Library
COM：Microsoft Excel 11.0 Object Library
简单封装的代码类：
using System;using System.Windows.Forms;using Excel = Microsoft.Office.Interop.Excel;namespace Northsnow.ExportExcel
{
class InsertPictureToExcel
{ /// <summary> /// 打开没有模板的操作。
/// </summary> public void Open() { this.Open(String.Empty); //调用另一个构造器 } /// <summary> /// 功能：实现Excel应用程序的打开 /// </summary> /// <param name="TemplateFilePath">模板文件物理路径</param> public void Open(string TemplateFilePath) { //打开对象 m_objExcel = new Excel.Application(); m_objExcel.Visible = false; m_objExcel.DisplayAlerts = false; if (m_objExcel.Version != "11.0") { MessageBox.Show("您的 Excel 版本不是 11.0 （Office 2003），操作可能会出现问题。"); m_objExcel.Quit(); return; } m_objBooks = (Excel.Workbooks)m_objExcel.Workbooks; if (TemplateFilePath.Equals(String.Empty)) { m_objBook = (Excel._Workbook)(m_objBooks.Add(m_objOpt)); } else { m_objBook = m_objBooks.Open(TemplateFilePath, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt, m_objOpt);
