使用ADO.net链接到csv格式的数据.

   DataTable dTab = new DataTable();

    protected void GetDataCSV()
    {

        string csvPath;
        csvPath = Server.MapPath("~/temp/");
        string cnnStr;
        cnnStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + csvPath + ";Extended Properties='text;HDR=YES;FMT=TabDelimited'";
        OleDbConnection cn = new OleDbConnection(cnnStr);
        string sql = "SELECT * FROM `jobsheet_trims_card.csv`";
        OleDbDataAdapter da = new OleDbDataAdapter(sql, cn);

        da.Fill(dTab);    // 填充DataSet

    }
