Dictionary _dic = new Dictionary();
Hashtable _ht = new Hashtable();
while (_dr.Read())
{
_ht.Clear();
for (int i = 0; i < _dr.FieldCount; i++)
{
_ht.Add(_dr.GetName(i),_dr[i]);
}
_dic.Add(_i,_ht);
_i++;
}
我原本是想循环记录集并将其添加到hashtable中,再将记录依次添加到dictionary里.但是每次循环后,dictionary里hashtable的值都变掉了（就是dictionary 和 dictionary里的所有hashtable都同步更新,都是一个值.）,该怎么改才能实现我要的结果呢?

Dictionary Dictionary _dic = new Dictionary();Hashtable _ht = new Hashtable();while (_dr.Read()){_ht.Clear();for (int i = 0; i < _dr.FieldCount; i++){_ht.Add(_dr.GetName(i),_dr[i]);}_dic.Add(_i,_ht);_i++;}我原本是想循环记录集并将其添加
Dictionary _dic = new Dictionary();
Hashtable _ht;
while (_dr.Read())
{
_ht=new Hashtable(); // 每个循环都创建一个新的对象
for (int i = 0; i < _dr.FieldCount; i++)
{
_ht.Add(_dr.GetName(i), _dr[i]);
}
_dic.Add(_i, _ht);
_i++;
}
dictionary放的是hashtable对象的引用.因为你只new 了一个hashtable对象,当然会出现同步更新的现象了.解决办法是每个循环都new一个hashtable对象.
