Question

I have the following data in a table:

e.g. data

0, 'Ford'    
1, 'Toyota, Toyota'  
2, 'BMW'  
3, 'Porsche, Porsche'  
4, 'BMW'  

I need to place this data in the following type List<Tuple<int, string>> carList so that the results within my list would appear as follows:

0, 'Ford'    
1, 'Toyota'  
2, 'BMW'  
3, 'Porsche'  
4, 'BMW'  

using the following pseudo code:

while (SQLiteDataReader.Read())  
{  
    carList.Add  
    (  
        new Tuple<int, string> (   
                                 SQLiteDataReader.GetInt32(0) ,   
                                 SQLiteDataReader.GetString(1).[Some extension method to produce unique items]
                               );
    )  
}

Note, when there are items with duplication (Toyota, Porsche) , the duplication will always be the same name. i.e you won’t get something like ‘Toyota, Ford’.

Is there some extension method that would remove the duplication part?

Answer 1

This should do the trick:

SQLiteDataReader.GetString(1).Split(',').First().Trim()
