 [![//Get the name of the First Sheet.
            using (OleDbConnection con = new OleDbConnection(conStr))
            {
                using (OleDbCommand cmd = new OleDbCommand())
                {
                    cmd.Connection = con;
                    con.Open();
                    DataTable dtExcelSchema = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
                    sheetName = dtExcelSchema.Rows\[0\]\["TABLE_NAME"\].ToString();
                    con.Close();
                }
            }

            //Read Data from the First Sheet.
            using (OleDbConnection con = new OleDbConnection(conStr))
            {
                using (OleDbCommand cmd = new OleDbCommand())
                {
                    using (OleDbDataAdapter oda = new OleDbDataAdapter())
                    {

                        cmd.CommandText = "SELECT * From \[" + sheetName + "\]";
                        cmd.Connection = con;
                        con.Open();
                        oda.SelectCommand = cmd;
                        oda.Fill(dtExcelData);
                        con.Close();

                        //Populate DataGridView.
                        //dataGridView1.DataSource = dt;
                    }
                }
            }

            dtExcelData = dtExcelData.AsEnumerable().Skip(2).Take(1).CopyToDataTable();

            return dtExcelData;][2]][2]
