Let R,S be arbitrary associative rings and RCS a semidualizing bimodule. We give some equivalent characterizations for R being left coherent (and right perfect) rings, left Noetherian rings and left Artinian rings in terms of the C-( FP-)injectivity, flatness and projectivity of character modules of certain left S-modules.
