基本for-loop示例是性能的基线。 第二个示例将随机数生成器包装在紧密循环中调用的函数中。 第三个示例在函数内移动循环。 该函数只调用一次,但代码仍生成相同的随机数。 请注意每个示例的执行时间差异。 Output CollectionSize Test TotalMilliseconds RelativeSpeed --- --- --- --- 5120 for-loop in a func...

Instead, we use this line of code in order to return a collection of all the files found in that folder:Copy Set colItems = objFolder.Items Once we have our collection, we then set up a For Each loop to loop through all the items in the collection. Inside the For Each loop, we...
