“/”应用程序中的服务器错误。
--------------------------------------------
外部表不是预期的格式。
说明: 执行当前 Web 请求期间，出现未经处理的异常。请检查堆栈跟踪信息，以了解有关该错误以及代码中导致错误的出处的详细信息。
异常详细信息: System.Data.OleDb.OleDbException: 外部表不是预期的格式。
网上查了好多！都说复制里面的内容到新建的Excel文件中再导入！
这样用户试用多麻烦！
我导出Excel的方法是通过HTTP输出流！
//http文件流 public void CreateExcel(DataSet ds, string FileName) { HttpResponse resp; resp = Page.Response; resp.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312"); resp.AppendHeader("Content-Disposition", "attachment;filename=" + FileName + ".xls"); string colHeaders = "", ls_item = ""; //定义表对象与行对象，同时用DataSet对其值进行初始化 DataTable dt = ds.Tables[0]; DataRow[] myRow = dt.Select();//可以类似dt.Select("id>10")之形式达到数据筛选目的 int i = 0; int cl = dt.Columns.Count; //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 < cl; i++) { if (i == (cl - 1))//最后一列，加n { colHeaders += dt.Columns[i].Caption.ToString() + "\n"; } else { colHeaders += dt.Columns[i].Caption.ToString() + "\t"; } } resp.Write(colHeaders); //向HTTP输出流中写入取得的数据信息 //逐行处理数据 foreach (DataRow row in myRow) { //当前行数据写入HTTP输出流，并且置空ls_item以便下行数据 for (i = 0; i < cl; i++) { if (i == (cl - 1))//最后一列，加n { ls_item += row[i].ToString() + "\n"; } else { ls_item += row[i].ToString() + "\t"; } } resp.Write(ls_item); ls_item = ""; } resp.End(); }public DataSet ds(){ string type2 = FileUpload1.FileName; var type3 = type2.Substring(type2.LastIndexOf('.')); if(type3.Equals(".xls") || type3.Equals(".xlsx")) { string newName = Server.MapPath("..//App_Data//Uploads//") + DateTime.Now.ToString("hhmmss") + ".xls"; FileUpload1.SaveAs(newName); string connStr = string.Empty; if (type3.Equals(".xlsx")) { connStr = "Provider=Microsoft.Ace.OleDb.12.0;Data Source=" + newName + ";Extended Properties='Excel 12.0 Xml; HDR=YES; IMEX=1'"; } else if (type3.Equals(".xls")) { connStr = "Provider=Microsoft.Jet.OleDb.4.0;" + "data source=" + newName + ";Extended Properties='Excel 8.0; HDR=YES; IMEX=1'"; } OleDbConnection conn = new OleDbConnection(connStr); if (conn.State.ToString() == "Closed") { conn.Open(); } DataTable dt = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null); var tableName = dt.Rows[0][2].ToString().Trim(); var str1 = string.Format("Select * from [{0}]", tableName); OleDbDataAdapter oda = new OleDbDataAdapter(str1, conn); DataSet ds = new DataSet(); oda.Fill(ds); conn.Close(); File.Delete( newName );return ds;}
[解决办法]
你那个方法不是很看的出问题 上面那个方式是我一直用的...看看吧 或许有帮助

是不是跟版本有关系呀
