Question

正在寻找解决方案，但无法找到一个好的解释。

我目前有代码将每次迭代的数组返回到电子表格的一行。在最后一次迭代中，它获取所有行数据并复制并将其粘贴到另一个工作表。我知道如果我可以创建一个巨大的数组，每个项目都是一个数据数组然后转换它而不需要复制和粘贴/操作单元格，那将会快一百万倍。

我该怎么做？对我来说更大的问题还在于每个主要迭代都是基于全局变量而不是子本身内的循环。这是因为用于为每次迭代生成数组的工作表数据需要时间加载到工作表中。

这是我的子代码。到目前为止，您可以看到在每个数据处写入数据范围（“A”和＆amp; pos），然后增加工作表本身的计数器。一旦子完成，全局变量迭代并再次假设......所以简而言之，数组或数组需要是一个全局变量

* 在任何人看之前说F 我不是在看所有代码，唯一重要的部分就像最后10行...其他一切只是为了清晰起见

看起来您的数组只是一维的。你需要创建二维数组，填充所有数组，然后你可以用一个语句将它写入工作表。

这是一个例子，你显然需要根据你的需要定制它（我说“ F，我不是在查看所有代码!!! ”）

Sub foo()
Dim arr(1 To 10, 1 To 5)  'creates an array 10 rows x 5 columns
Dim x As Long
Dim y As Long

For x = LBound(arr, 1) To UBound(arr, 1)
    For y = LBound(arr, 2) To UBound(arr, 2)
        arr(x, y) = Application.WorksheetFunction.RandBetween(1, 100)
    Next
Next

'Put it on the sheet:
Range("A1").Resize(UBound(arr, 1), UBound(arr, 2)).Value = arr


End Sub

在vba中创建一个数组的全局变量数组并转置为工作表
