computing w, b for soft margin SVM

When we compute w from the alphas for the soft-margin SVM which values of alpha do we include? only margin support vectors ( those with 0 < alpha_n < C)? or do we include all of them (0 < alpha_n <= C)?

Similarly, when computing b, can we use any support vector? or only margin support vectors?
