Well, I know a few but some of them were only kidnapped for a (few) episode(s).
Like. Ciel Phantomhive, July from DTB, Ikuto Tsukiyomi from Shugo Chara, Asuna from SOA, Amano Yukiteru from Mirai Nikki...
I guess...xD
Like Ikuto Tsukiyomi he was kidnapped for almost a whole season from his twisted stepfather to use him for his own evil plans. xD (picture)

Rin from 犬夜叉 was kidnapped few times (by Kagura, the child snatcher demon and Magatsuhi).

Also Kaoru from Rurouni Kenhin (or Samurai x) was kidnapped 由 Jinei. She was really mad :)
