C#如何导出一个Excel表格多个sheet页
C#如何导出一个Excel 多个sheet页？（如果能以导出的Excel表格为模板在导入，另加200分）要好使的代码，无bug！ 要看清楚是导出多个sheet页
protected void Button6_Click(object sender, EventArgs e)
{
string table_name = "joa_equip_info" + ".xls";//表名
EquipBiz biz = new EquipBiz();
EquipVo vo = new EquipVo();
string id = Request["id"];
DataSet ds = biz.findInfoDs(id);
Equce equce = new Equce();
equce.CreateExcel(ds, table_name);
}
public DataSet findInfoDs(string id)
{
string sql = "select *from info1 where id='" + id + "'" +" select * from info2 where id='"+id+"'"+" select * from info3 where id='"+id+"'";+" select * from info4 where id='"+id+"'";+" select * from info5 where id='"+id+"'";;
return ComData.jdataset(sql);
//调用数据层略
}
public void TableEquceExcel(DataSet ds, string FileName)
{
如何写？？？？
}
补充：equce.CreateExcel(ds, table_name);写错了应该是TableEquceExcel(ds, table_name)
追问：！你能不能自己写啊！不要转载别人的！Excel.dll文件这个文件没有！要有我早就用了！
答案： string ExcelName = "设备列表" + ".xls";//导出的Excel表格名
string sql = "select * from joa_equip_class select * from joa_equip_info select * from joa_equip_parket_class select * from joa_equip_maintenance";
DataSet ds = ComData.jdataset(sql);
string[][] ArrName ={ new string[] { "类别大", "类别小", "类别名", "排序", "系统时间", "备注" }, new string[] { "设备编号", "设备名称", "设备型号", "生产厂家", "生产日期", "技术状态", "存放位置", "负责人", "配属单位", "条形码", "有效期", "类别id", "存放位置id", "设备照片" }, new string[] { "类别id大", "类别id小", "存放位置", "货物号", "保管人", "备注", "排序" }, new string[] { "设备名称", "设备编号", "责任单位", "责任人", "维护保养费", "维护保养性质", "详细说明" } };
string[][] ArrDs ={ new string[] { "parent_id", "class_id", "class_name", "order_id", "systime", "remark" }, new string[] { "equip_id", "name", "model", "factory", "production_date", "state", "store", "duty_name", "unit", "bar", "useful_time", "class_id", "parket_id", "photo" }, new string[] { "parent_id", "parket_id", "class_name", "goods_nums", "person", "remark", "order_id" }, new string[] { "equip_name", "equip_id","duty_bum", "duty_name", "money", "kind", "explain" } };
string[] SheetName ={ "类别表", "设备列表" ,"存储位置表","维护保养记录表"};
Equce eq = new Equce();
eq.ToExcel(ds, ArrName, ArrDs, ExcelName, SheetName);//数据DataSet,列名,列数据名,Excel表格名,sheet页名
--------------------------------------------------------------------------------------------------------------------
//导出一个或多个数据表
public void ToExcel(DataSet ds, string[][] ArrName, string[][] ArrDs, string ExcelName, string[] Sheet_Name)
{
AppLibrary.WriteExcel.XlsDocument doc = new AppLibrary.WriteExcel.XlsDocument();
//doc.FileName = "Report.xls";
doc.FileName = HttpUtility.UrlEncode(ExcelName, System.Text.Encoding.UTF8);//防止导出Excel乱码
string SheetName = string.Empty;
int k = ds.Tables.Count;//表的个数
for (int i = 0; i < k; i++)
{
//SheetName = "当前是SHEET" + i.ToString();
SheetName = Sheet_Name[i].ToString();
AppLibrary.WriteExcel.Worksheet sheet = doc.Workbook.Worksheets.Add(SheetName);
AppLibrary.WriteExcel.Cells cells = sheet.Cells;
for (int j = 1; j <= ArrName[i].Length; j++)//加入标题
{
if (ArrName[i][j - 1] != "")
cells.Add(1, j, ArrName[i][j - 1].ToString());
}
int f = 1;
int a = ds.Tables[i].Rows.Count; ;
for (int m = 0; m < a; m++)
{
f++;
for (int n = 1; n <= ArrDs[i].Length; n++)//循环列
{
if (ArrDs[i][n - 1] != "")
cells.Add(f, n, ds.Tables[i].Rows[m][ArrDs[i][n - 1]].ToString());
}
}
}
doc.Send();
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
}
由于EXCEL 2003有65536行数据的限制,故在超过这个限制时须分成多个Sheet来显示,本人通过网上部分资料加上自己的应用心得总结出以下方法,希望能为广大工友带来方便.
首先,如果您使用的是VS2005,则须引入Excel.dll文件;如果您使用的是VS2003,则引入Interop.Excel.dll文件,一般工程会自动引入.
然后,引用命名空间:using Excel;
最后添加方法:
/// <summary>
/// 将传入的DataSet数据导出至Excel文件
/// </summary>
/// <param name="ctl">DataGrid</param>
public static void DataSet2Excel(DataSet ds)
{
int maxRow=ds.Tables[0].Rows.Count;
string fileName=DateTime.Now.ToString("yyyyMMddhhmmss") + ".xls";//设置导出文件的名称
DataView dv=new DataView(ds.Tables[0]);//将DataSet转换成DataView
string fileURL=string.Empty;
//调用方法将文件写入服务器,并获取全部路径
fileURL=DataView2ExcelBySheet(dv,fileName);
//获取路径后从服务器下载文件至本地
HttpContext curContext=System.Web.HttpContext.Current;
curContext.Response.ContentType="application/vnd.ms-excel";
curContext.Response.ContentEncoding=System.Text.Encoding.Default;
curContext.Response.AppendHeader("Content-Disposition", ("attachment;filename=" + fileName));
curContext.Response.Charset = "";
curContext.Response.WriteFile(fileURL);
curContext.Response.Flush();
curContext.Response.End();
}
/// <summary>
/// 分Sheet导出Excel文件
/// </summary>
/// <param name="dv">需导出的DataView</param>
/// <returns>导出文件的路径</returns>
private static string DataView2ExcelBySheet(DataView dv,string fileName)
{
int sheetRows=65535;//设置Sheet的行数,此为最大上限,本来是65536,因表头要占去一行
int sheetCount = (dv.Table.Rows.Count - 1) / sheetRows + 1;//计算Sheet数
GC.Collect();//垃圾回收
Application excel;
_Workbook xBk;
_Worksheet xSt=null;
excel = new ApplicationClass();
xBk = excel.Workbooks.Add(true);
//定义循环中要使用的变量
int dvRowStart;
int dvRowEnd;
int rowInd
