這篇文章主要介紹了asp.net導出Excel類庫代碼，有需要的朋友可以參考一下
代碼如下: using System; using System.Collections.Generic; using System.Reflection; using System.Web; using Excel = Microsoft.Office.Interop.Excel; /// <summary> ///ExcelClass 的摘要說明 /// </summary> public class ExcelClass { /// <summary> /// 構建ExcelClass類 /// </summary> public ExcelClass() { this.m_objExcel = new Excel.Application();
