循环通过指定范围内的单元格 [英] loop through cells in named range

问题描述

我正在尝试编写一个循环遍历一个范围内的所有单元格的代码。最终我想做一些比较复杂的事情，但是由于我遇到麻烦，我决定创建一些简短的测试程序。第一个示例工作正常，但第二个（具有命名范围）不会（给出Object Range of Object_Global Failed错误消息）。关于我做错什么的任何想法？我真的很想用一个命名范围做这个...谢谢！

I am trying to write code that will loop through all cells in a range. Eventually I want to do something more complicated, but since I was having trouble I decided to create some short test programs. The first example works fine but the second (with a named range) doesn't (gives a "Method Range of Object_Global Failed" error message). Any ideas as to what I'm doing wrong? I'd really like to do this with a named range... Thanks!

作品：

Sub foreachtest()
Dim c As Range
For Each c In Range("A1:A3")
    MsgBox (c.Address)
Next
End Sub

无效：

Sub foreachtest2()
Dim c As Range    
Dim Rng As Range
Set Rng = Range("A1:A3")
For Each c In Range("Rng")
    MsgBox (c.Address)
Next
End Sub

推荐答案

要调整第二个代码，您需要认识到您的范围rng现在是一个代表范围的变量，并将其视为：

To adjust your second code, you need to recognize that your range rng is now a variable representing a range and treat it as such:

Sub foreachtest2() 
Dim c As Range     
Dim Rng As Range 
Set Rng = Range("A1:A3") 
For Each c In rng
    MsgBox (c.Address) 
Next 
End Sub 

警告：大多数情况下，如果您可以避免循环，代码将更快g通过范围。

Warning: most of the time, your code will be faster if you can avoid looping through the range.
