.net 导出复杂格式的EXCEL

首先要添加EXCEl引用在网上搜一下应该就能找到添加的方法，注意要跟服务器中的EXCEl版本一直然后在cs中添加using Microsoft.Office.Interop.Excel;using Microsoft.Office.Core;using System.Reflection;using System.IO;可能还有别的，自己看VS提示加吧然后在Web.config中下加入计算机登陆的用户名密码，这是给予程序权限调用EXCEL DLL下面就是方法了添加一个DataTable就能导出EXCEl了注意网页编码 中文乱码问题 这个就自己解决吧哈哈，下面这个是我项目中用到的一个小例子 自己看着改吧
[csharp] 
/// <summary>  
/// 导出Excel  
/// </summary>  
/// <param name="dt">要导出的DataTable</param>  
public void ExportToExcel(System.Data.DataTable dt)  
{  
    if (dt == null) return;  
    Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();  
    if (xlApp == null)  
    {  
        // lblMsg.Text = "无法创建Excel对象，可能您的机子未安装Excel";  
        lblMsg.Text = GetLocalResourceObject("noexcel").ToString();  
        return;
