Array Function

  • 项目

This page is specific to the Visual Basic for Applications (VBA) Language Reference for Office 2010.

Returns a Variant containing an array.

Syntax

Array(arglist)

The required arglist argument is a comma-delimited list of values that are assigned to the elements of the array contained within the Variant. If no arguments are specified, an array of zero length is created.

Remarks

The notation used to refer to an element of an array consists of the variable name followed by parentheses containing an index number indicating the desired element. In the following example, the first statement creates a variable named A as a Variant. The second statement assigns an array to variable A. The last statement assigns the value contained in the second array element to another variable.

Dim A As Variant
A = Array(10,20,30)
B = A(2)

The lower bound of an array created using the Array function is determined by the lower bound specified with the Option Base statement, unless Array is qualified with the name of the type library (for example VBA.Array). If qualified with the type-library name, Array is unaffected by Option Base.

Note

A Variant that is not declared as an array can still contain an array. A Variant variable can contain an array of any type, except fixed-length strings and user-defined types. Although a Variant containing an array is conceptually different from an array whose elements are of type Variant, the array elements are accessed in the same way.

Example

This example uses the Array function to return a Variant containing an array.

Dim MyWeek, MyDay
MyWeek = Array("Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun")
' Return values assume lower bound set to 1 (using Option Base
' statement).
MyDay = MyWeek(2)    ' MyDay contains "Tue".
MyDay = MyWeek(4)    ' MyDay contains "Thu".
