晕，原来你不知道怎么绑定，一个例子

SqlConnection cnn = new SqlConnection( "server=CNN;database=foodshop;uid=sa;password= ");
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = new SqlCommand( "select id, food_id, food_name from food ", cnn);
DataSet ds = new DataSet();
da.Fill(ds, "myFood ");
DataTable dt = ds.Tables[ "myFood "];

//绑定数据
ddl.DataSource = dt;
ddl.DataValueField = "food_id ";
ddl.DataTextField = "food_name ";
ddl.DataBind();

看amandag(高歌)给的代码，已经很全面了
