ios - Type casting in C# for xamarin -

i want convert nsmutablearray cllocationcoordinates2d[]

i tried following gave me error ,(this kind of type case not allowed)

nsmutablearray* arrtest ;  // had added cllocationcoordinates2d objects  cllocationcoordinates2d[] locations = (cllocationcoordinates2d[])arrtest 

how convert?

if have nsarray need cast in c# array, following:

var locations = nsarray.fromarray<cllocationcoordinate2d>(arrtest); 

however, considering apple apis in xamarin.ios return c# array instead of nsarray, need this. if created nsmutablearray yourself, i'd suggest use list< cllocationcoordinate2d> instead.
