converting resultset from OleDbDataReader into list

Question

Consider a Winforms app connecting to a SQL Server 2008 database and running a SQL SELECT statement:

string myConnectionString = \"Provider=SQLOLEDB         


        

Answer 1

Assume you have defined a class that is something like

class MyData
{
    public string Name {get; set;}
    public int FinalConc {get; set;} // or whatever the type should be
}

You would iterate through the results of your query to load a list.

List list = new List();
while (myReader.Read())
{
    MyData data = new MyData();
    data.Name = (string)myReader["name"];
    data.FinalConc = (int)myReader["finalconc"]; // or whatever the type should be
    list.Add(data);
}

// work with the list

If you just need one of the given fields, you can forego the class definition and simply have a List, where T is the type of whatever field you want to hold.
