protected void Button1_Click(object sender, EventArgs e) 
     { 
      if (FileUpload1.HasFile) 
      { 
       string path = string.Concat((Server.MapPath("~/temp/" + FileUpload1.FileName))); 
       FileUpload1.PostedFile.SaveAs(path); 
       OleDbConnection oledbcon = new OleDbConnection("PROVIDER=MICROSOFT.ACE.OLEDB.12.0;DATA Source=" + path + ";Extended Properties=Excel 12.0;"); 
       OleDbCommand cmd = new OleDbCommand("SELECT * FROM [sheet1$]", oledbcon); 
       OleDbDataAdapter ObjAdapter = new OleDbDataAdapter(cmd); 
       oledbcon.Open(); 
       DbDataReader dr = cmd.ExecuteReader(); 
       string con_str = @"Data Source=RANGANATH;Initial Catalog=Ndexpress;Integrated Security=True";

시도해보십시오.

string excelPath = Server.MapPath("~/Files/") + Path.GetFileName(fuFile.PostedFile.FileName); 
     fuFile.SaveAs(excelPath); 

     string conString = string.Empty; 
     string extension = Path.GetExtension(fuFile.PostedFile.FileName); 
     switch (extension) 
     { 
      case ".xls": //Excel 97-03 
       conString = ConfigurationManager.ConnectionStrings["Excel03ConString"].ConnectionString; 
       break; 
      case ".xlsx": //Excel 07 or higher 
       conString = ConfigurationManager.ConnectionStrings["Excel07ConString"].ConnectionString; 
       break; 

     } 
     conString = string.Format(conString, excelPath); 
     using (OleDbConnection excel_con = new OleDbConnection(conString)) 
     { 
      excel_con.Open(); 
      string sheet1 = excel_con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null).Rows[0]["TABLE_NAME"].ToString(); 
      DataTable dtExcelData = new DataTable(); 

      //OPTIONAL 
      dtExcelData.Columns.AddRange(new DataColumn[3] { new DataColumn("Emp_Id", typeof(int)), 
      new DataColumn("Emp_Name", typeof(string)), 
      new DataColumn("Emp_Salary",typeof(decimal)) }); 

      using (OleDbDataAdapter oda = new OleDbDataAdapter("SELECT * FROM [" + sheet1 + "]", excel_con)) 
      { 
       oda.Fill(dtExcelData); 
      } 
      excel_con.Close(); 

      string consString = ConfigurationManager.ConnectionStrings["constr"].ConnectionString; 
      using (SqlConnection con = new SqlConnection(consString)) 
      { 
       using (SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(con)) 
       { 
        sqlBulkCopy.DestinationTableName = "dbo.tblEmps"; 

        //OPTIONAL 
        sqlBulkCopy.ColumnMappings.Add("Emp_Id", "Emp_Number"); 
        sqlBulkCopy.ColumnMappings.Add("Emp_Name", "Emp_Name"); 
        sqlBulkCopy.ColumnMappings.Add("Emp_Salary", "Emp_Salary"); 
        con.Open(); 
        sqlBulkCopy.WriteToServer(dtExcelData); 
        con.Close(); 
       } 
      } 
     } 

이이 문제를 해결할 수있는, 잘 web.config 파일

<connectionStrings> 
    <add name="Excel03ConString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties='Excel 8.0;HDR={1}'"/> 
    <add name="Excel07ConString" connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties='Excel 8.0;HDR={1}'"/> 
</connectionStrings>
