读取Excel工作表数据并绑定ASP.NET GridView

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"; SqlBulkCopy bulkinsert = new SqlBulkCopy(con_str); bulkinsert.DestinationTableName = "deliveries"; bulkinsert.WriteToServer(dr); oledbcon.Close(); Array.ForEach(Directory.GetFiles((Server.MapPath("~/temp"))), File.Delete); Label1.ForeColor = Color.Green; Label1.Text = "Succssfully Added"; FetchData(); } } 

当这个应用程序运行显示此错误 – ： {"The 'MICROSOFT.ACE.OLEDB.12.0' provider is not registered on the local machine."}

解决办法是什么？

尝试这个。

 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(); } } } 

在web.config文件中添加这个

  <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>
