How do I copy an Array class array into a builtin array?

Question

I am trying to copy what is in a Array class array into a builtin array but I keep getting a "InvalidCastException: Cannot cast from source type to destination type." error. Here is my code.

 var arr = new Array ();
 //assigning numbers to arr
 for(var i= 0; i < newDataParsed["data"].length; i++){
 arr.Push (newDataParsed["data"][i][key4]);
 }
 //testing to see what is in arr and numbers come back like they are supposed to.
 for(var j = 0; j < arr.length; j++){
 print(arr[j]);
 }

Does anybody know what is happening here or another way to copy an Array class array into a builtin array? Any suggestions would be great. Thanks. //And here is where the error happens var builtinArray : int[] = array1.ToBuiltin(int);

The problem is that the type of your array "arr" is not int.

Most likely it is a string array.

So you cannot copy a string array into an int array, you need to convert it first.

you could try:

 var builtinArray : int[] = new int[arr.length];

 for(var i = 0; i < builtinArray.Length;i++){
 builtinArray[i] =  parseInt(arr[i]);
 }

or something similar

That worked well thank you. Length should have a lowercase l but otherwise worked great :)

oops, my mistake.. for the built-in array it would be capital, which is why I got confused (as seen in my fixed answer above :>)
