How do I loop through rows with a data reader in C#?

Question

I know I can use while(dr.Read()){...} but that loops every field on my table, I want to retrieve all the values from the first row, and then second... and so o

There is no way to get "the whole row" at once - you need to loop through the rows, and for each row, you need to read each column separately:

using(SqlDataReader rdr = cmd.ExecuteReader())
{
    while (rdr.Read())
    {
        string value1 = rdr.GetString(0);
        string value2 = rdr.GetString(1);
        string value3 = rdr.GetString(2);
    }
}

What you do with those strings that you read for each row is entirely up to you - you could store them into a class that you've defined, or whatever....
