{
DataSet ds = new DataSet();
DataTable dt = new DataTable();
DataColumn coll = dt.Columns.Add("Title", typeof(string));
coll.AllowDBNull = false;
coll.Unique = true; DataRow dr;

for (int i = 0; i < 10; i++)
{
dr = dt.NewRow();//新行
dr["Title"] = "" + i + "列数据";
dt.Rows.Add(dr);
}

ds.Tables.Add(dt);


ExportDataToExcel(dt, "续办人事代理");
//CreateExcel(ds, "aa.xls");
}

}
sw.WriteLine(colstr);

System.Web.HttpContext.Current.Response.Write(sw);
System.Web.HttpContext.Current.Response.End();
}
catch (Exception ex)
{

}
}




public static void ExportDataToExcelByWeb(DataTable dt,System.Web.UI.WebControls.DataGrid DGOutPut,string FileName)

System.Web.HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");//设置输出流为简体中文
System.Web.HttpContext.Current.Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。
DGOutPut.EnableViewState = false;
System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN", true);
System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad);
