may help you . the data in SqlDataReader can be like a matrix, it depends on the query. The next snippet shows you how you can get each "cell" in your SqlDataReader:
//This "while" iterates through all rows!
    //This "for" iterates through each column of the current row!
    for (int i = 0; i < MysqlData.FieldCount; i++)

  public static class DataRecordExtensions
            public static bool HasColumn(this IDataRecord dr, string columnName)
                for (int i=0; i < dr.FieldCount; i++)
                    if (dr.GetName(i).Equals(columnName, StringComparison.InvariantCultureIgnoreCase))
                        return true;
                return false;
public static bool HasColumn(DbDataReader Reader, string ColumnName) { 
    foreach (DataRow row in Reader.GetSchemaTable().Rows) { 
        if (row["ColumnName"].ToString() == ColumnName) 
            return true; 
    } //Still here? Column not found. 
    return false;
