用Com.Excel导出只有一个工作薄的Excel代码如下所示,请问怎么改代码,能导出一个Excel文件有多个工作薄 /*使用示例:
* DataSet ds=(DataSet)Session["AdBrowseHitDayList"];//本ds中有多个Dt
string ExcelFolder=Assistant.GetConfigString("ExcelFolder");
string FilePath=Server.MapPath(".")+"\\"+ExcelFolder+"\\";
//生成列的中文对应表
Hashtable nameList = new Hashtable();
nameList.Add("ADID", "广告编码");
nameList.Add("ADName", "广告名称");
nameList.Add("year", "年");
nameList.Add("month", "月");
nameList.Add("browsum", "显示数");
nameList.Add("hitsum", "点击数");
nameList.Add("BrowsinglIP", "独立IP显示");
nameList.Add("HitsinglIP", "独立IP点击");
//利用excel对象
DataToExcel dte=new DataToExcel();
string filename="";
try
{
if(ds.Tables[0].Rows.Count>0)
{
filename=dte.DataExcel(ds.Tables[0],"标题",FilePath,nameList);
}
}
catch
{
//dte.KillExcelProcess();
}
if(filename!="")
{
Response.Redirect(ExcelFolder+"\\"+filename,true);
}

找找看应该有创建worksheet的方法
Excel.Workshee excelWorksheet = (Excel.Worksheet)excelSheets.get_Item(currentSheet);
Excel.Worksheet objSheet=(Excel.Worksheet) newWorkbook.Worksheets.Add(excelWorksheet,Type.Missing,Type.Missing,Type.Missing);
方法就不挨个说了,网上一搜都是一堆
