可以退出Do...使用Exit Do语句Loop。 例如,若要退出无限循环,请在 If... 的True语句块中使用Exit Do语句。然后。。。Else语句或Select Case语句。 如果条件为False,循环将照常运行。 在以下示例myNum中,分配了一个值,该值创建无限循环。If...Then...Else语句将检查此条件,然后退出,从而阻止无限循环。
Loops are used for repeating a set of statements multiple times. There are different types of loops in VBA: For Loop, For Each, Do While & Do Until loops.
此示例演示了如何使用“Do...Loop”语句。 内部Do...循环语句循环 10 次,询问用户是否应继续运行,在选择“否”时将标志的值设置为False,并使用Exit Do语句提前退出。 外部循环在检查该标志的值时立即退出。 VB复制 PublicSubLoopExample()DimCheckAsBoolean, CounterAsLong, TotalAsLongCheck =True: Counter =0...
