vb.net 初始化更多维数组赋值和循环访问

在 VB.NET 中，你可以初始化任意维度的数组，只需在定义数组时指定相应的维度即可。以下是一个初始化八维数组并赋值的示例代码：

Dim arr(,,,, ,,,) As Integer = New Integer(1, 2, 3, 4, 5, 6, 7, 8) {}

For i As Integer = 0 To 1
    For j As Integer = 0 To 2
        For k As Integer = 0 To 3
            For l As Integer = 0 To 4
                For m As Integer = 0 To 5
                    For n As Integer = 0 To 6
                        For o As Integer = 0 To 7
                            For p As Integer = 0 To 8
                                arr(i, j, k, l, m, n, o, p) = i + j + k + l + m + n + o + p
                            Next
                        Next
                    Next
                Next
            Next
        Next
    Next
Next

在上面的示例中，我们定义了一个八维数组 `arr`，其维度分别为 2、3、4、5、6、7、8 和 9。我们使用嵌套的循环对数组进行遍历，将每个元素的值设置为其各个维度的下标之和。

接下来是在 VB.NET 中循环访问八维数组的示例代码：

For i As Integer = 0 To 1
    For j As Integer = 0 To 2
        For k As Integer = 0 To 3
            For l As Integer = 0 To 4
                For m As Integer = 0 To 5
                    For n As Integer = 0 To 6
                        For o As Integer = 0 To 7
                            For p As Integer = 0 To 8
                                Console.WriteLine("arr({0}, {1}, {2}, {3}, {4}, {5}, {6}, {7}) = {8}", i, j, k, l, m, n, o, p, arr(i, j, k, l, m, n, o, p))
                            Next
                        Next
                    Next
                Next
            Next
        Next
    Next
Next

在上面的示例中，我们使用嵌套的循环对数组进行遍历，并使用 `Console.WriteLine` 函数输出每个元素的值以及其各个维度的下标。

无论是初始化多少维的数组，在 VB.NET 中都可以使用类似的方式实现。
