Evaluating a sum from terms generated by the Array function

I want to evaluate a sum from a series I created using the Array function. For example; I specify Array[((-1)^(# + 1) (x)^#)/# ! &, 3, 1 ] which gives me the following 3 terms of output: {x, -(x^2/2), x^3/6} Can anyone tell if and how I can turn these 3 terms into a sum to be evaluated?
