add item to dropdownlist

I'm trying to add an item to a DropDownList from an Oracle datareader, but I keep getting an error that states the line has some invalid arguments.

Can I simply specify the text and the value? In which case, I want them to be the same value coming from the datareader.

TRef.Items.Add(new ListItem(dr["t_ref"], dr["t_ref"]));

dr["t_ref"] returns object. 

TRef.Items.Add(new ListItem(dr["t_ref"].ToString(), dr["t_ref"].ToString()));

ListItem can take two strings as parameters, you are passing two objects. Try converting the dr object to a string:

TRef.Items.Add(new ListItem(dr["t_ref"].ToString(), dr["t_ref"].ToString()));

Alternatively to be cleaner:

 var t_ref = dr["t_ref"].ToString();
 TRef.Items.Add(new ListItem(t_ref, t_ref));
