c# - Fastest way to initialise a numeric array

[Guest]

I want to set all elements in a numeric array to a value other than 0.
The default numeric initialisers set the elements to 0.
Is looped assignment the fastest way, or is there an equivalent to the C RTL
memset.

Cheers

You can do this:

int[] numbers = new int[]{1,2,3,4,5,6,7,8,9};

Thanks Ron,

But I have a rather large number of elements, and I don't really want to
clutter code-space with a constant initialise.

You might have to loop through the elements. If you need to instantiate the
same array multiple times, you might want to create an instance when the app
starts and then just copy/clone the array as you need it.

Create once the object and then clone it using
either serialization or .clone
