Can IEnumerable be an alternative to Params[]?

Question

Can IEnumerable be a possible alternative to params[]?

Because Ive been hearing some articles that params is not good, but I seem to doubt it because it is syntactically straightforward and is very useful.

ex.

public void testMeth(IEnumerable<object> testerEnum){
    //Code here
}

There is a difference. See this question: http://stackoverflow.com/questions/7580277/why-use-the-params-keyword — Bernard, Jul 09 '15 at 01:39
Do your really need to test meth you got? :) I just love how you can cut some words... — Alexei Levenkov, Jul 09 '15 at 02:03

Using the params keyword importantly allows callers of your method not to wrap the arguments into a collection at all.

With:

public bool testMeth(params object[] input){
    // ... things
    return purity >= REQUIRED_PURITY; //this is how to test meth, right?
}

The caller can call

var is_good = testMeth("apples", new object(), 7);

with no need to make their own array.

This is an excellent, and practical, interpretation of the OP's business logic. +1 – Mark Miller Jul 09 '15 at 01:55
We can't always be serious. Sometimes you just have take the opportunities to be a little silly. – moreON Jul 09 '15 at 02:11
