[Android.Runtime.Register("copyOf", "([II)[I", "")]
public static int[] CopyOf (int[] original, int newLength);

[<Android.Runtime.Register("copyOf", "([II)[I", "")>]
static member CopyOf : int[] * int -> int[]

Parameters

original: Int32[]

the array to be copied

newLength: Int32

the length of the copy to be returned

Returns

Int32[]

a copy of the original array, truncated or padded with zeros to obtain the specified length

Attributes: RegisterAttribute

Exceptions

NegativeArraySizeException

if newLength

NullPointerException

if original == null

Remarks

Copies the specified array, truncating or padding with zeros (if necessary) so the copy has the specified length. For all indices that are valid in both the original array and the copy, the two arrays will contain identical values. For any indices that are valid in the copy but not the original, the copy will contain 0. Such indices will exist if and only if the specified length is greater than that of the original array.
