c# Leaner way of initializing int array

Having the following code is there a leaner way of initializing the array from 1 to the number especified by a variable?

int nums=5;
int[] array= new int[nums];

for(int i=0;i<num;i++)
{
   array[i] = i;
}

Maybe with linq or some array.function?

Maybe I'm missing something here, but here is the best way I know of:

int[] data = new int [] { 383, 484, 392, 975, 321 };

from MSDN

even simpler:

int[] data = { 383, 484, 392, 975, 321 };

Use Enumerable.Range() method instead of. Don't forget to add System.Linq namespace. But this could spend little bit high memory. You can use like;

int[] array = Enumerable.Range(0, nums).ToArray();

Generates a sequence of integral numbers within a specified range.
