string path = Server.MapPath(this.xlfile.Text+".xls");
System.IO.FileInfo file = new System.IO.FileInfo(path);
Response.Clear();
Response.Charset="GB2312";
Response.ContentEncoding=System.Text.Encoding.UTF8;
// 添加头信息，为"文件下载/另存为"对话框指定默认文件名
Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode(file.Name));
// 添加头信息，指定文件大小，让浏览器能够显示下载进度
Response.AddHeader("Content-Length", file.Length.ToString());
// 指定返回的是一个不能被客户端读取的流，必须被下载
Response.ContentType = "application/ms-excel";
// 把文件流发送到客户端
Response.WriteFile(file.FullName);
// 停止页面的执行
Response.End();

如果你的网页的meta设置是gb2312，那么charset最好设置成utf-8,和contentencoding一样。
如果你有checkbox，选择导出的话，那么在判断时，!checked的项设置dataGrid1.items[i].style["display"] = "none",以防出现乱码

理解错了，我用的是下面的代码
int rowIndex=1;
string User_ID="3";
Sql.TSqlDB db=new Sql.TSqlDB();
string strSel="select * from tb_sjsj where User_ID='"+User_ID+"' order by id asc";
SqlDataAdapter sqldata=new SqlDataAdapter(strSel,db.SqlConn);
DataSet myset=new DataSet();
sqldata.Fill(myset,"tb_sjsj");
db.SqlConn.Close();
Excel.Application app = new Excel.ApplicationClass();
Object oMissing = System.Reflection.Missing.Value;
Excel.Workbook oBook = app.Workbooks.Add(oMissing);
app.Cells[1,1]="编号";
app.Cells[1,2]="用户编号";
app.Cells[1,3]="序号";
app.Cells[1,4]="井号";
//将所得到的表的列名,赋值给单元格
app.Cells[1,5]="油田";
app.Cells[1,6]="区块";
app.Cells[1,7]="依据地质方案 ";
app.Cells[1,8]=" 施工目的";
app.Cells[1,9]=" 设计日期 ";
app.Cells[1,10]="设计人";
app.Cells[1,11]=" 套管状况 ";
app.Cells[1,12]=" 设计工序1 ";
app.Cells[1,13]="设计工序2";
app.Cells[1,14]="设计工序3";
app.Cells[1,15]="设计工序4 ";
app.Cells[1,16]=" 设计工序5";
app.Cells[1,17]=" 设计工序6 ";
app.Cells[1,18]="设计工序7";
app.Cells[1,19]=" 存在问题 ";
app.Cells[1,20]="分合注 ";
app.Cells[1,21]=" 层数 ";
app.Cells[1,22]=" 最小层间距 ";
app.Cells[1,23]="封隔器型号";
app.Cells[1,24]="封隔器深度";
app.Cells[1,25]="校深 ";
app.Cells[1,26]=" 备注";
foreach(DataRow row in myset.Tables["tb_sjsj"].Rows)
{
rowIndex++;
int colIndex=0;
foreach(DataColumn col in myset.Tables["tb_sjsj"].Columns)
{
colIndex++;
app.Cells[rowIndex,colIndex]=row[col.ColumnName].ToString().Trim();
}
}
app.Visible=true;
oBook.Saved = true;
app.UserControl = false;

简单点，先保存在服务器端，然后Response.Redirect("xls文件");
