In VB, dynamic arrays can be resized at any time, while static arrays can only be resized in advance. Excessive use of this method will reduce the running environment of memory.

There are two types of arrays in Visual Basic: fixed-size arrays? It always keeps the same size and a dynamic array, and its size can be changed at runtime.

In Visual Basic, dynamic array is the most flexible and convenient, which helps to manage memory effectively. For example, you can use a large array for a short time and then release memory space to the system when you are not using the array.

If you don't use dynamic arrays, you should declare an array as large as possible and then delete those unnecessary elements. But if this method is overused, the running environment of memory will slow down.
