在VBA中使用声明为Dim Array（）为Variant的数组与Dim Array为Variant的数组之间的区别是什么？

Question

What's difference between two declarations Dim Array_1() as Variant and Dim Array_2 as Variant in VBA ?

If I then create arrays using above declarations :

Array_1 = Range("A1:A10")
Array_2 = Range("A1:A10")

in locals windows I see different descriptions for Array_1 and Array_2. I seems that Array_2 contain values of undefined type. Could I ReDim Array_2 ?

Answer 1

Dim Arraytest() as Variant

Declare's a variable called Arraytest which is setup as an array The above can be used like below

ReDim Arraytest(9)

or

ReDim Arraytest(1 To 10)

To setup an array of 10 values - Arraytest(0) to Arraytest(9) in the first case and Arraytest(1) to Arraytest(10) in the second case.

Dim Arraytest as Variant

Declare's a variable called Arraytest which is setup as a single varaible - note the second code can not be used as an array

Note: Array can not be used as a variable name - used Arraytest in the above
