Read data from SqlDataReader

Question

I have a SQL Server 2008 database and I am working on it in the backend. I am working on asp.net/C#

SqlDataReader rdr = cmd.ExecuteReader();  
while (rdr.Read())  
{              
   //how do I read strings here????  
}  

I know that the reader has values. My SQL command is to select just 1 column from a table. The column contains strings ONLY. I want to read the strings (rows) in the reader one by one. How do I do this?

Answer 1

using(SqlDataReader rdr = cmd.ExecuteReader())
{
    while (rdr.Read())
    {
        var myString = rdr.GetString(0); //The 0 stands for "the 0'th column", so the first column of the result.
        // Do somthing with this rows string, for example to put them in to a list
        listDeclaredElsewhere.Add(myString);
    }
}
