Advancing Array

[Susan]

In C++ you could do something like
int[] key = something;
functionCall (key+1);

Where the array key would be sent in but the 0 position in the function call
would be the first position in the key array. Is there a way to do this in C#
without creating a temp array to send in to the functionCall?

Thank you,
Susan

No, but normally you would just add additional parameters that specify the
offset and length of the elements that you want to process.

No. You can't have references/pointers to anything other than the start of
an object [except see "fixed" and C# pointers which you shouldn't normlly
use]

The cleanest and most general way to do this is to have your function take
an IList<int> and create a delegate class too expose part of your array as
an IList<int>

The most efficient way is to pass start-index and length as well as the
array.
