如何在vba for excel中初始化多维数组变量

问题描述

Microsoft 站点建议以下代码应该可以工作:>

Dim numbers = {{1, 2}, {3, 4}, {5, 6}}

但是，当我尝试在 Excel VBA 模块中使用它时出现编译错误.以下确实适用于一维数组:

A = 数组(1, 2, 3, 4, 5)

但是，我还没有设法找到对 2D 数组执行相同操作的方法.有什么想法吗?

解决方案

您还可以使用利用 Evaluate 函数和静态数组的速记格式.在下面的代码中，设置了 varData，其中 [] 是 Evaluate 函数和 {...} 表达式表示一个静态数组.每行以 ; 分隔，每个字段以 , 分隔.它使您获得与 simoco 代码相同的最终结果，但语法更接近您的原始问题:

Sub ArrayShorthand()Dim varData As VariantDim intCounter1 作为整数Dim intCounter2 作为整数' 设置数组变量数据 = [{1, 2, 3;4、5、6；7, 8, 9}]' 测试对于 intCounter1 = 1 到 UBound(varData, 1)对于 intCounter2 = 1 到 UBound(varData, 2)Debug.Print varData(intCounter1, intCounter2)下一个 intCounter2下一个 intCounter1结束子

The Microsoft site suggests the following code should work:

Dim numbers = {{1, 2}, {3, 4}, {5, 6}}

However I get a complile error when I try to use it in an excel VBA module.The following does work for a 1D array:

A = Array(1, 2, 3, 4, 5)

However I have not managed to find a way of doing the same for a 2D array.Any ideas?

解决方案

You can also use a shorthand format leveraging the Evaluate function and a static array. In the code below, varData is set where [] is the shorthand for the Evaluate function and the {...} expression indicates a static array. Each row is delimited with a ; and each field delimited with a ,. It gets you to the same end result as simoco's code, but with a syntax closer to your original question:

Sub ArrayShorthand()

    Dim varData As Variant
    Dim intCounter1 As Integer
    Dim intCounter2 As Integer

    ' set the array
    varData = [{1, 2, 3; 4, 5, 6; 7, 8, 9}]

    ' test
    For intCounter1 = 1 To UBound(varData, 1)
        For intCounter2 = 1 To UBound(varData, 2)
            Debug.Print varData(intCounter1, intCounter2)
        Next intCounter2
    Next intCounter1

End Sub
