You cannot modify the size of an array. But you can create a new array with an increased length, copy the original array over, and assign the last element.

array<String^>^ copy = gcnew array<String^>(part->Length + 1);
for (int j = 0; j < part->Length; ++j)
    copy[j] = part[j];
copy[copy->Length-1] = ...

Btw: your index i will run out of bounds. You have to replace <= by <.
