ASP.NET(C#)将数据导出到Word或Excel

1) ASP.NET(C#)将数据导出到Word或Excel
命名空间：
using System.IO;
using System.Text;
将DataGrid的数据导出到Excel
string excelname="excel文件名";
HttpContext.Current.Response.Charset = "GB2312";
HttpContext.Current.Response.ContentEncoding = Encoding.UTF8;
HttpContext.Current.Response.ContentType = "application/ms-excel";
HttpContext.Current.Response.AppendHeader("Content-disposition", "attachment;filename=" + excelname + ".xls");
dr1.Page.EnableViewState = false;
StringWriter sw = new StringWriter();
HtmlTextWriter tw = new HtmlTextWriter(sw);
dr1.RenderControl(tw);
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.Response.End();
将DataGrid的数据导出到Word
string excelname="word文件名";
HttpContext.Current.Response.Charset = "GB2312";
HttpContext.Current.Response.ContentEncoding = Encoding.UTF8;
HttpContext.Current.Response.ContentType = "application/ms-winword";
HttpContext.Current.Response.AppendHeader("Content-disposition", "attachment;filename=" + excelname + ".doc");
dr1.Page.EnableViewState = false;
StringWriter sw = new StringWriter();
HtmlTextWriter tw = new HtmlTextWriter(sw);
dr1.RenderControl(tw);
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.Response.End();
ASP.NET 2.0,C#----利用GridView控件导出其他文件（导出Excel，导出Word文件）
// 注意，在Visual Studio2005平台下，如果使用GridView导出文件，
//就必须重载VerifyRenderingInServerForm方法
public override void VerifyRenderingInServerForm(Control control)
{
}
/// <summary>
/// 导出到文件的方法，
/// </summary>
/// <param name="Model">Model=1:导出为Execl，Model=2:导出为Word </param>
private void toFiles(int Model)
{

HC.Response.Clear();
HC.Response.Buffer = true;
HC.Response.ContentEncoding = System.Text.Encoding.UTF8;//设置输出流为简体中文
if (Model == 1)
{
//---导出为Excel文件
HC.Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(strFileName, System.Text.Encoding.UTF8) + ".xls");
HC.Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。

HC.Response.Write(sw.ToString());
HC.Response.End();
