Select only first 2 items in an iEnumerable

Help

Hi, I have an iEnumerable collection, how do I select only the first 2 items without looping? i’ve seen the code somewhere it looks like next() and skip() but I’m not exactly sure how it works

Try this:

newdt = myDataTable.AsEnumerable().Take(2).CopyToDataTable

so if I want to extract it as an Array, is this the code?

arr = enum.Take(2).ToArray?

yes @DEATHFISH that should work…

ok now the error that I’m facing is that enum is type iEnumerable<Object> and I want to produce arr which is of type String[]. What is the most efficient way of doing this?
