小弟要将EXCEL表格中的数据导入到MYSQL数据库中,求解该怎么写,导出已经可以了,但是导入的时候不知道怎么弄,怎么将EXCEL表格中的数据提取出来,注意是MYSQL不是SQLSERVER

  1.   


    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
    }

    用"Provider=Microsoft.Jet.OleDb.4.0;" + "data source=" + newName + ";Extended Properties='Excel 8.0; HDR=YES; IMEX=1'"时会报错说provider关键字不支持,这个是什么问题
