dr is an SqlDataReader[^], right?
Its Item[^] property is indexed. Indexes in C# are given in square brackets like here

C#

li.Value = dr.Item[0];

For the other part, I can only guess that l is of type System.Web.UI.Controls.ListItem[^]. Its Value[^] property is of type System.String[^], just as the other property you set. Therefore you cannot assign a zero to it (the parentheses do exactly nothing here). Use

C#

l.Value = "0";

instead. Or, if the zero represents a variable, use that variable's ToString[^] overload.
