Abstract: Let T be a formal triangular matrix ring, where R and S are associative rings with identity element, C is a faithfully semidualizing (S,R)-bimodule. It is showed that: 1) M is a Ding C-projective left S-module; 2) N is Ding C-injective left R-module. The obtained conclusions establish links between Ding C-modules and Ding modules through T.

Key words: formal triangular matrix ring, semidualizing module, Ding projective (injective) module, Ding C-projective (C-injective) module
