asp.net里导出excel表方法汇总

张文

1、由dataset生成
public void CreateExcel(DataSet ds,string typeid,string FileName)
  {
HttpResponse resp;
resp = Page.Response;
resp.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
resp.AppendHeader("Content-Disposition", "attachment;filename=" + FileName);
string colHeaders= "", ls_item="";
int i=0;

//定义表对象与行对像，同时用DataSet对其值进行初始化
DataTable dt=ds.Tables[0];
DataRow[] myRow=dt.Select("");
// typeid=="1"时导出为EXCEL格式文件；typeid=="2"时导出为XML格式文件
if(typeid=="1")
{
//取得数据表各列标题，各标题之间以\t分割，最后一个列标题后加回车符
for(i=0;i    colHeaders+=dt.Columns.Caption.ToString()+"\t";
colHeaders +=dt.Columns.Caption.ToString() +"\n";
//向HTTP输出流中写入取得的数据信息
resp.Write(colHeaders);
//逐行处理数据
foreach(DataRow row in myRow)
{
   //在当前行中，逐列获得数据，数据之间以\t分割，结束时加回车符\n
   for(i=0;i    ls_item +=row.ToString() + "\t";
   ls_item += row.ToString() +"\n";
   //当前行数据写入HTTP输出流，并且置空ls_item以便下行数据
   resp.Write(ls_item);
   ls_item="";
}
}
else
{
if(typeid=="2")
{
   //从DataSet中直接导出XML数据并且写到HTTP输出流中
   resp.Write(ds.GetXml());
}
}
//写缓冲区中的数据到HTTP头文件中
resp.End();

  }
2、由datagrid生成
public void ToExcel(System.Web.UI.Control ctl)
  {
HttpContext.Current.Response.AppendHeader("Content-Disposition","attachment;filename=Excel.xls");
HttpContext.Current.Response.Charset ="UTF-8";
HttpContext.Current.Response.ContentEncoding =System.Text.Encoding.Default;
HttpContext.Current.Response.ContentType ="application/ms-excel";//image/JPEG;text/HTML;image/GIF;vnd.ms-excel/msword
ctl.Page.EnableViewState =false;
System.IO.StringWriter  tw = new System.IO.StringWriter() ;
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter (tw);
ctl.RenderControl(hw);
HttpContext.Current.Response.Write(tw.ToString());
HttpContext.Current.Response.End();
  }

用法：ToExcel(datagrid1);

3、这个用dataview
public void OutputExcel(DataView dv,string str)
{
//
// TODO: 在此处添加构造函数逻辑
//
                        //dv为要输出到Excel的数据，str为标题名称
GC.Collect();
Application excel;// = new Application();
int rowIndex=4;
int colIndex=1;

_Workbook xBk;
_Worksheet xSt;

excel= new ApplicationClass();

xBk = excel.Workbooks.Add(true);

xSt = (_Worksheet)xBk.ActiveSheet;

//
//取得标题
//
foreach(DataColumn col in dv.Table.Columns)
{
colIndex++;
excel.Cells[4,colIndex] = col.ColumnName;
xSt.get_Range(excel.Cells[4,colIndex],excel.Cells[4,colIndex]).HorizontalAlignment = XlVAlign.xlVAlignCenter;//设置标题格式为居中对齐
}

//
//取得表格中的数据
//
foreach(DataRowView row in dv)
{
rowIndex ++;
colIndex = 1;
foreach(DataColumn col in dv.Table.Columns)
{
   colIndex ++;
   if(col.DataType == System.Type.GetType("System.DateTime"))
   {
   excel.Cells[rowIndex,colIndex] = (Convert.ToDateTime(row[col.ColumnName].ToString())).ToString("yyyy-MM-dd");
   xSt.get_Range(excel.Cells[rowIndex,colIndex],excel.Cells[rowIndex,colIndex]).HorizontalAlignment = XlVAlign.xlVAlignCenter;//设置日期型的字段格式为居中对齐
   }
   else
   if(col.DataType == System.Type.GetType("System.String"))
   {
   excel.Cells[rowIndex,colIndex] = "'"+row[col.ColumnName].ToString();
   xSt.get_Range(excel.Cells[rowIndex,colIndex],excel.Cells[rowIndex,colIndex]).HorizontalAlignment = XlVAlign.xlVAlignCenter;//设置字符型的字段格式为居中对齐
   }
   else
   {
   excel.Cells[rowIndex,colIndex] = row[col.ColumnName].ToString();
   }
}
}
//
//加载一个合计行
//
int rowSum = rowIndex + 1;
int colSum = 2;
excel.Cells[rowSum,2] = "合计";
xSt.get_Range(excel.Cells[rowSum,2],excel.Cells[rowSum,2]).HorizontalAlignment = XlHAlign.xlHAlignCenter;
//
//设置选中的部分的颜色
//
xSt.get_Range(excel.Cells[rowSum,colSum],excel.Cells[rowSum,colIndex]).Select();
xSt.get_Range(excel.Cells[rowSum,colSum],excel.Cells[rowSum,colIndex]).Interior.ColorIndex = 19;//设置为浅黄色，共计有56种
//
//取得整个报表的标题
//
excel.Cells[2,2] = str;
//
//设置整个报表的标题格式
//
xSt.get_Range(excel.Cells[2,2],excel.Cells[2,2]).Font.Bold = true;
xSt.get_Range(excel.Cells[2,2],excel.Cells[2,2]).Font.Size = 22;
//
//设置报表表格为最适应宽度
//
xSt.get_Range(excel.Cells[4,2],excel.Cells[rowSum,colIndex]).Select();
xSt.get_Range(excel.Cells[4,2],excel.Cells[rowSum,colIndex]).Columns.AutoFit();
//
//设置整个报表的标题为跨列居中
//
xSt.get_Range(excel.Cells[2,2],excel.Cells[2,colIndex]).Select();
xSt.get_Range(excel.Cells[2,2],excel.Cells[2,colIndex]).HorizontalAlignment = XlHAlign.xlHAlignCenterAcrossSelection;
//
//绘制边框
//
xSt.get_Range(excel.Cells[4,2],excel.Cells[rowSum,colIndex]).Borders.LineStyle = 1;
xSt.get_Range(excel.Cells[4,2],excel.Cells[rowSum,2]).Borders[XlBordersIndex.xlEdgeLeft].Weight = XlBorderWeight.xlThick;//设置左边线加粗
xSt.get_Range(excel.Cells[4,2],excel.Cells[4,colIndex]).Borders[XlBordersIndex.xlEdgeTop].Weight = XlBorderWeight.xlThick;//设置上边线加粗
xSt.get_Range(excel.Cells[4,colIndex],excel.Cells[rowSum,colIndex]).Borders[XlBordersIndex.xlEdgeRight].Weight = XlBorderWeight.xlThick;//设置右边线加粗
xSt.get_Range(excel.Cells[rowSum,2],excel.Cells[rowSum,colIndex]).Borders[XlBordersIndex.xlEdgeBottom].Weight = XlBorderWeight.xlThick;//设置下边线加粗
//
//显示效果
//
excel.Visible=true;

//xSt.Export(Server.MapPath(".")+"\\"+this.xlfile.Text+".xls",SheetExportActionEnum.ssExportActionNone,Microsoft.Office.Interop.OWC.SheetExportFormat.ssExportHTML);
xBk.SaveCopyAs(Server.MapPath(".")+"\\"+this.xlfile.Text+".xls");

ds = null;
         xBk.Close(false, null,null);

         excel.Quit();
         System.Runtime.InteropServices.Marshal.ReleaseComObject(xBk);
         System.Runtime.InteropServices.Marshal.ReleaseComObject(excel);
System.Runtime.InteropServices.Marshal.ReleaseComObject(xSt);
         xBk = null;
         excel = null;
xSt = null;
         GC.Collect();
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));

// 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();

:lol朋友，我昨天在刚刚发的asp.net数据导出EXCEL，并在EXCEL中进行分页显示的代码！希望对你有帮助,你的我就不客气的记下来啦哈，互相学习一下

protected void btnExcel_Click(object sender, EventArgs e)
{
//导出数据到EXCEL
string modeFile = Server.MapPath("PrintProvider.xls");
string tempFile = Server.MapPath("ProviderTemp.xls");//取Excel报表模板
File.Copy(tempFile, modeFile, true);
Excel.Application xExcel = new Excel.ApplicationClass();//创建excel对象
Excel.Workbook xBook = xExcel.Workbooks.Open(modeFile, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
Excel.Worksheet xSheet = (Excel.Worksheet)xBook.Worksheets[1];
try
{
string sqlStr;
sqlStr = "select * from PM_notice";
DataTable dt = Class1.GetDsFromSql(sqlStr).Tables[0];
//查询结果数据
int count = dt.Rows.Count;
int page = 0;
if (count % 15 == 0)
{
page = count / 15;
}
else
{
page = count / 15 + 1;
}
if (page == 0) page = 1;
int sheet = 1;
int tempSheet = sheet;
int p;
for (p = 1; p < page; p++)
{
xSheet = (Excel.Worksheet)xBook.Worksheets[tempSheet];
xSheet.Copy(Type.Missing, xBook.Worksheets[tempSheet]);
tempSheet++;
}
xBook.Save();
int index = 0;
for (p = 0; p < page; p++)
{
xSheet = (Excel.Worksheet)xBook.Worksheets[sheet++];
int row = 3;//jjjjjjjjjjjjj
for (int i = p * 15; i < (p + 1) * 15 && i < count; i++)
{
index++;
xSheet.Cells[row, 1] = index.ToString();//序号列
xSheet.Cells[row, 2] = dt.Rows[i]["title"].ToString();
xSheet.Cells[row, 3] = dt.Rows[i]["content"].ToString();

row++;
}
