How to restrict sort function to affect original array

Question

I had used array.sort function to sorting an array, but this function not return new array but affected older.

To keep an original array, I create new array manualy, but sort function just affected both new array and original

Dim newardata = ardata
array.sort(newardata)

What should i do to keep that original array, thanks

Yes, it is an efficient in-place sort. Consider the Linq OrderBy() extension method to create a new collection. — Hans Passant

You aren't creating a new array in your code. Try cloning the array.

Dim newardata = ardata.Clone()
array.sort(newardata)

You could also try OrderBy.
