asp.net导出excel

[T_long]

画了一个table导出的excel的，但是导 出来的不是标准的格式
怎么导出一个标准的excel
这个是导出的代码

System.Web.HttpContext.Current.Response.Clear();
        System.Web.HttpContext.Current.Response.Buffer = true;
        System.Web.HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
        System.Web.HttpContext.Current.Response.Charset = "GB2312";
        HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
        System.Web.HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment; filename=" + MainID + SubID + Date + ".xls");
        System.Web.HttpContext.Current.Response.Write(content.ToString());
        System.Web.HttpContext.Current.Response.End();

去搜下这个东西
Aspose.Cells
这个在导出 Excel 的 时候相当不错.

[昵称可以很长很长很长]

用 org.in2bits.MyXls 这个组件试试，网上有教程。我一直再用

[孟子E章]

你这是html的格式的，标准的格式要使用Microsoft.Office.Interop.Excel.

用文件流导出试试！

服务器上面没有装excel，可以用这个using Microsoft.Office.Interop.Excel吗？
我以前就是用的这个导出，导入的，可是发布以后就报错了

[孟子E章]

服务器上需要安装啊，xls文件格式没公开，只能Excel程序可以生成完全标准的格式。

[孟子E章]

asp.net程序 不建议使用这个，一般导出兼容的格式就可以了，

他们说装上excel不安全，不让安装

出了这两个方法导出，还有其他的方法吗？导出的时候里面有个下拉框的设置

调用的时候
protected void Page_Load(object sender, EventArgs e)
{
var isExport = Request.Form["hidIsExport"] == null ? false : bool.Parse(Request.Form["hidIsExport"]);

if (isExport) //如果是导出命令，则导出
{
var str = Request.Form["hidContent"];
string decodeStr = Server.UrlDecode(str);//解码
CommonMethod.ExportToExcel(Response, "MarketingActivityReport.xls", decodeStr);
}
}
上面hidContent就是要导出的内容

[應燁軍]

Aspose.Cells +1 ...这个我用过不错，不需要office支持,重要的是有破解版

[likevs]

这种功能需求现在都普遍化了，网上已有很多完美的方案了，自己选

你的导出excel的方法，好像少了个中重要的方法，给你个实例：地址

[peng_hai_bo]

推荐你个 OpenXml或者CloseXml 这两个插件，都不需要在服务器上安装Excel的 只适合Excel2007或以上的，因为微软在2007开始Excel的地层结构改成了用XML来组成

[Ryan20082009]

我给你一个例子，我已经测试成功的：
1、执行导出按钮
//导出客户信息。
protected void but_ExcelImport_Click(object sender, EventArgs e)
{
HQSoft.HQBLL.TB_Customer tbBll = new HQBLL.TB_Customer();
Aspose.Cells.Workbook workBook = new Aspose.Cells.Workbook();
Aspose.Cells.Worksheet sheet = workBook.Worksheets[0];
DataTable dt = tbBll.GetList("").Tables[0];
for (int i = 0; i < dt.Rows.Count; i++)
{
sheet.Cells[0, 0].PutValue("客户编号");
sheet.Cells[0, 1].PutValue("客户名称");
sheet.Cells[0, 2].PutValue("客户全称");
sheet.Cells[0, 3].PutValue("快捷录入");
sheet.Cells[0, 4].PutValue("客户类型");
sheet.Cells[0, 5].PutValue("业务人员");
sheet.Cells[0, 6].PutValue("客户主联系人");
sheet.Cells[0, 7].PutValue("客户主联系电话");
sheet.Cells[0, 8].PutValue("客户邮件");
sheet.Cells[0, 9].PutValue("客户地址");
sheet.Cells[0, 10].PutValue("客户传真");
sheet.Cells[0, 11].PutValue("结算周期");
sheet.Cells[0, 12].PutValue("结算方式");
DataRow dr = dt.Rows[i];
sheet.Cells[i + 1, 0].PutValue(dt.Rows[i][1]);
sheet.Cells[i + 1, 1].PutValue(dt.Rows[i][2]);
sheet.Cells[i + 1, 2].PutValue(dt.Rows[i][3]);
sheet.Cells[i + 1, 3].PutValue(dt.Rows[i][4]);
sheet.Cells[i + 1, 4].PutValue(dt.Rows[i][5]);
sheet.Cells[i + 1, 5].PutValue(dt.Rows[i][6]);
sheet.Cells[i + 1, 6].PutValue(dt.Rows[i][7]);

sheet.Cells[i + 1, 7].PutValue(dt.Rows[i][8]);
sheet.Cells[i + 1, 8].PutValue(dt.Rows[i][9]);
sheet.Cells[i + 1, 9].PutValue(dt.Rows[i][10]);
sheet.Cells[i + 1, 10].PutValue(dt.Rows[i][11]);
sheet.Cells[i + 1, 11].PutValue(dt.Rows[i][12]);
sheet.Cells[i + 1, 12].PutValue(dt.Rows[i][13]);
}
string fileName = "";
fileName = "Customer_" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls"; // 文件名
workBook.Save(Server.MapPath("../Customer/tmpCustomer/" + fileName));
DownLoadFile(Server.MapPath("../Customer/tmpCustomer/"), fileName);
}

[Ryan20082009]

2、 //导出时候下载并上传临时文件。
private bool DownLoadFile(string _FilePath, string _FileName)
{
try
{
System.IO.FileStream fs = System.IO.File.OpenRead(_FilePath + "\\" + _FileName);
byte[] FileData = new byte[fs.Length];
fs.Read(FileData, 0, (int)fs.Length);
Response.Clear();
Response.AddHeader("Content-Type", "application/ms-excel");
string FileName = System.Web.HttpUtility.UrlEncode(System.Text.Encoding.UTF8.GetBytes(_FileName));
Response.AddHeader("Content-Disposition", "inline;filename=" + System.Convert.ToChar(34) + FileName + System.Convert.ToChar(34));
Response.AddHeader("Content-Length", fs.Length.ToString());
Response.BinaryWrite(FileData);
fs.Close();
//删除服务器临时文件
//System.IO.File.Delete(_FilePath + "\\" + _FileName);
Response.Flush();
Response.End();
return true;
}
catch (Exception ex)
{
ex.Message.ToString();
return false;
}
}
public override void VerifyRenderingInServerForm(Control control)
{
}
3、 //Excel导入DtataSet操作。
public DataSet ExecleToDataSet(string filenameurl, string table)
{
DataSet ds = new DataSet();
try
{
string strConn = "Provider=Microsoft.Jet.OleDb.4.0;" + "data source=" + filenameurl + ";Extended Properties='Excel 8.0; HDR=YES; IMEX=1'";
OleDbConnection conn = new OleDbConnection(strConn);
OleDbDataAdapter odda = new OleDbDataAdapter("select * from [Sheet1$]", conn);
odda.Fill(ds, table);
}
catch (Exception)
{
Page.ClientScript.RegisterStartupScript(this.GetType(), "", "<script>alert('Excel文件数据有误！');</script>");

}
return ds;
}
4、导入
//确定导入
protected void but_tmp_Import_Click(object sender, EventArgs e)
{

if (this.FileUpload1.FileName.ToString() == "")
{
Response.Write("<script language='javascript'>alert('导入文件不能为空，请先上传!');</script>");

return;

else

string path = Server.MapPath("~/Excel/");
string filetime = DateTime.Now.ToString("yyyyMMddHHmmss");//时间字段区分文件（同名文件覆盖）
string fiepath = path + "\\" + filetime + "\\" + FileUpload1.FileName;
//string fiepath = path + "\\" + fu_Excel.FileName;
if (!System.IO.Directory.Exists(path + "\\" + filetime))
{
System.IO.Directory.CreateDirectory(path + "\\" + filetime);
}
FileUpload1.PostedFile.SaveAs(fiepath);
//上传操作。
DataSet ds = ExecleToDataSet(fiepath, FileUpload1.FileName);
if (ds.Tables.Count == 0)
{

return;

return;
