How to copy part of an array to another array in C#?

How can I copy a part of an array to another array?

Consider I'm having

int[] a = {1,2,3,4,5};

Now if I give the start index and end index of the array a it should get copied to another array.

Like if I give start index as 1 and end index as 3, the elements 2, 3, 4 should get copied in the new array.

Solution 1:

int[] b = new int[3];
Array.Copy(a, 1, b, 0, 3);

• a = source array
• 1 = start index in source array
• b = destination array
• 0 = start index in destination array
• 3 = elements to copy

Solution 2:

See this question. LINQ Take() and Skip() are the most popular answers, as well as Array.CopyTo().

A purportedly faster extension method is described here.
