如何将hashtable赋值给dropdownlist

Answer 1

dropDownList1.Items.AddRange(hashtable.Cast<DictionaryEntry>().Select(x => new ListItem(x.Value.ToString(), x.Key.ToString())).ToArray());

或者

foreach (DictionaryEntry entry in hashtable)
dropDownList1.Items.Add(new ListItem(entry.Value.ToString(), entry.Key.ToString()));

Answer 2

可以用最原始的办法：遍历Hashtable,每个DictionaryEntry的key赋值给ListItem的值，value赋值给ListItem的Text。
