兩者之間沒有任何可比性的。
DataSet是一數(shù)據(jù)存儲的類,你可以把數(shù)據(jù)庫中的數(shù)據(jù)讀取到內(nèi)存中,在內(nèi)存中按照DataSet這種格式進(jìn)行數(shù)據(jù)的統(tǒng)計。而DataReader是一種讀取數(shù)據(jù)的方式,也可以認(rèn)為是內(nèi)存中數(shù)據(jù)與數(shù)據(jù)庫中數(shù)據(jù)的一種橋梁,例如,我們可以通過DataReader把數(shù)據(jù)庫中數(shù)據(jù)讀到內(nèi)存表中(DataSet)中。
而DataReader與DataAdapter是有可比性的,兩者都是存取數(shù)據(jù)的一種,DataReader是以一種只性方式進(jìn)行讀取的,性能上要高于DataAdapter;但DataAdapter卻是數(shù)據(jù)聯(lián)系的一種橋梁,可以把DataSet中的數(shù)據(jù)通過Adapter更新到數(shù)據(jù)庫中。雖然Adapter在讀取時性能不高,但他可以建立DataSet與數(shù)據(jù)庫之間的聯(lián)系,從而實現(xiàn)DataSet中的更新。在不同的情況下,選用不同的數(shù)據(jù)方式。
