    private DataTable BuildDataTable()
    {
        var dt = new DataTable();

        using (var textReader = new StreamReader(_path))
        {
            using (var csv = new CsvReader(textReader))
            {
                csv.ReadHeader();
                foreach (var header in csv.FieldHeaders)
                {
                    dt.Columns.Add(header);
                }


                while (csv.Read())
                {
                    var row = dt.NewRow();
                    foreach (DataColumn column in dt.Columns)
                    {
                        row[column.ColumnName] = csv.GetField(column.DataType, column.ColumnName);
                    }
                    dt.Rows.Add(row);
                }
            }
        }

        return dt;
    }
