解决方案二：
在VB.NET同样可以将报表导出到Excel和Word进行输出，制作出专业水平的报表。具体操作如下：(注：首先需添加引用，选择COM-->选择MicrosoftWordObjectLibrary和MicrosoftExcelObjectLibrary组件)PrivateFunctionCreaTable()AsDataTableDimdtAsNewDataTable()dt.Columns.Add("列1",GetType(String))dt.Columns.Add("列2",GetType(Integer))dt.Columns.Add("列3",GetType(String))dt.Columns.Add("列4",GetType(String))Dimrow,row1AsDataRowrow=dt.NewRow()row!列1="行1"row!列2=1row!列3="d"row!列4="a"dt.Rows.Add(row)row1=dt.NewRow()row1!列1="行2"row1!列2=12row1!列3="b"row1!列4="c"dt.Rows.Add(row1)ReturndtEndFunction'2.将表中的内容导出到ExcelDimxlAppAsNewExcel.Application()DimxlBookAsExcel.WorkbookDimxlSheetAsExcel.WorksheetDimrowIndexAsInteger=1DimcolIndexAsInteger=0xlBook=xlApp.Workbooks().AddxlSheet=xlBook.Worksheets("sheet1")DimTableAsNewDataTable()Table=CreaTable()'将所得到的表的列名,赋值给单元格DimColAsDataColumnDimRowAsDataRowForEachColInTable.ColumnscolIndex=colIndex+1xlApp.Cells(1,colIndex)=Col.ColumnNameNext'得到的表所有行,赋值给单元格ForEachRowInTable.RowsrowIndex=rowIndex+1colIndex=0ForEachColInTable.ColumnscolIndex=colIndex+1xlApp.Cells(rowIndex,colIndex)=Row(Col.ColumnName)NextNextWithxlSheet.Range(.Cells(1,1),.Cells(1,colIndex)).Font.Name="黑体"'设标题为黑体字.Range(.Cells(1,1),.Cells(1,colIndex)).Font.Bold=True'标题字体加粗.Range(.Cells(1,1),.Cells(rowIndex,colIndex)).Borders.LineStyle=1'设表格边框样式EndWithWithxlSheet.PageSetup.LeftHeader=""&Chr(10)&"&""楷体_GB2312,常规""&10公司名称："'&Gsmc.CenterHeader="&""楷体_GB2312,常规""公司人员情况表&""宋体,常规"""&Chr(10)&_"&""楷体_GB2312,常规""&10日期：".RightHeader=""&Chr(10)&"&""楷体_GB2312,常规""&10单位：".LeftFooter="&""楷体_GB2312,常规""&10制表人：".CenterFooter="&""楷体_GB2312,常规""&10制表日期：".RightFooter="&""楷体_GB2312,常规""&10第&P页共&N页"EndWithxlApp.Visible=True'3.将表中的内容导出到WORDDimwordAppAsNewWord.Application()DimmyDocAsWord.DocumentDimoTableAsWord.TableDimrowIndex,colIndexAsIntegerrowIndex=1colIndex=0wordApp.Documents.Add()myDoc=wordApp.ActiveDocumentDimTableAsNewDataTable()Table=CreaTable()oTable=myDoc.Tables.Add(Range:=myDoc.Range(Start:=0,End:=0),_NumRows:=Table.Rows.Count+1,NumColumns:=Table.Columns.Count)'将所得到的表的列名,赋值给单元格DimColAsDataColumnDimRowAsDataRowForEachColInTable.ColumnscolIndex=colIndex+1oTable.Cell(1,colIndex).Range.InsertAfter(Col.ColumnName)Next'得到的表所有行,赋值给单元格ForEachRowInTable.RowsrowIndex=rowIndex+1colIndex=0ForEachColInTable.ColumnscolIndex=colIndex+1oTable.Cell(rowIndex,colIndex).Range.InsertAfter(Row(Col.ColumnName))NextNextoTable.Borders.InsideLineStyle=1oTable.Borders.OutsideLineStyle=1wordApp.Visible=True

解决方案四：
你要是操作Excel的API就比较麻烦了用OLEDB连上比较容易的
解决方案五：
StringWritersw=newStringWriter();sw.WriteLine("编号,状态,操作量");for(inti=0;i<数据List.Count;i++){sw.WriteLine(数据List[i].编号+"','"+数据List[i].状态+"','"+数据List[i].操作量);}sw.Close();Response.AddHeader("Content-Disposition","attachment;filename="+文件名+".xls");Response.ContentType="application/ms-excel";Response.ContentEncoding=System.Text.Encoding.GetEncoding("GB2312");Response.Write(sw);Response.End();其中的“数据List”为泛型数据源。
