目前开发环境是：vs2010 ASP.NET MVC2 ，想在MVC中导出Excel,方式无所谓，我可以传一个dataTable或者dataSet，说白了就是在mvc2中实现dataTable或者dataSet导出Excel。(以前在普通的asp.net项目中也开发过类似导出的功能，但是在MVC中貌似不同)，请做过类似功能的把源代码粘贴出来，包括引用什么命名空间？在线等，比较急，遇到合适答案马上结贴给分。谢谢！

给个例子吧，希望对你有帮助。
#region 导出用户信息到Excel
/// <summary>
/// 导出用户信息到Excel
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void btnExcelOut_Click(object sender, EventArgs e)

Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");//使输出的中文不乱码
