如何使用VBScript比较数组与数组?

问题描述

我想检查文件中的数据是否存在，是否存在数组数据.如果退出，它将返回1和0.我的文件里面是这样的:

I would like to check a data in my file exist or not in an array data that I have. It will return 1 and 0 if its exit or not. Inside my file is like this:

2j2H4F6d9d0d3hdfasgt.y7

但是我删了最后两行.我的数组数据是这样的:[2w fr 5k 2j 0w].我想检查我的文件中是否存在数组数据.

But I cut the last 2 lines. And my array data is like this: [2w fr 5k 2j 0w]. I want to check whether my array data exist inside my file.

Const wbemFlagReturnImmediately = &h10
Const wbemFlagForwardOnly = &h20

XX = 0

Set wshShell = CreateObject("WScript.Shell")

strFBString = wshShell.ExpandEnvironmentStrings("%FB%")

WScript.Echo "==>"
WScript.Echo "strFBString: " & strFBString

Set wshShell = Nothing

For i = 1 To Len(strFBString) Step 2
    If StrComp(Mid(strFBString, i, 2), [2w fr 5k 2j 0w]) = 0 Then
        XX = 1
    End If
Next

WScript.Echo "XX: " & XX

WScript.Quit(XX)

推荐答案

一方面，[2w fr 5k 2j 0w]在VBScript中不是有效的数组定义.如果要使用这5个字符串元素定义数组，则需要这样做:

For one thing, [2w fr 5k 2j 0w] is not a valid array definition in VBScript. If you want to define an array with these 5 string elements you need to do it like this:

Array("2w", "fr", "5k", "2j", "0w")

此外，StrComp()用于将一个字符串与另一个字符串进行比较.它不支持将字符串与数组进行比较.为了将字符串与数组的每个元素进行比较，您需要一个循环.但是，如何建立该循环取决于您要获得的结果.

Also, StrComp() is for comparing a string to another string. It does not support comparing a string to an array. For comparing a string to each element of an array you need a loop. How to build that loop depends on the result you want to achieve, though.

查看您的代码，似乎您想在2j2H4...中找到一个匹配项，而不是在w2j2H...中找到一个匹配项，因此简单地使用InStr()可能对您不起作用.在这种情况下，您可以使用内部循环进行比较:

Looking at your code it seems you want to find a match in 2j2H4..., but not in w2j2H..., so simply using InStr() probably won't work for you. In that case you could use an inner loop for the comparison:

ref = Array("2w", "fr", "5k", "2j", "0w")
For i = 1 To Len(strFBString) Step 2
    For Each s In ref
        If Mid(strFBString, i, 2) = s Then
            '...
        End If
    Next
Next

但是正如我已经说过的那样，细节取决于所需的最终结果.如果要检查输入字符串是否包含数组值的 any ，可以执行以下操作:

But like I already said, details depend on the desired end result. If you want to check if your input string contains any of the array values you could do something like this:

ref   = Array("2w", "fr", "5k", "2j", "0w")
found = False
For i = 1 To Len(strFBString) Step 2
    For Each s In ref
        If Mid(strFBString, i, 2) = s Then
            found = True
            Exit For
        End If
    Next
Next

另一方面，如果您要检查输入字符串是否包含参考字符串的 all ，则可能会执行以下操作:

If on the other hand you wanted to check if your input string contains all of the reference strings you'd probably do something like this instead:

ref   = Array("2w", "fr", "5k", "2j", "0w")
For Each s In ref
    found = False
    For i = 1 To Len(strFBString) Step 2
        If Mid(strFBString, i, 2) = s Then
            found = True
            Exit For
        End If
    Next
    If Not found Then Exit For
Next

您还可以使用完全不同的方法，例如将数据放入字典中.

You could also use an entirely different approach, like putting your data in a dictionary:

data = CreateObject("Scripting.Dictionary")
For i = 1 To Len(strFBString) Step 2
    data(Mid(strFBString, i, 2)) = True
Next

使用这种方法，您可以检查数据是否包含任何参考值，如下所示:

Using that approach you could check if the data contains any of the reference values like this:

found = False
For s In Array("2w", "fr", "5k", "2j", "0w")
    If data.Exists(s) Then
        found = True
        Exit For
    End If
Next

或检查数据是否包含所有像这样的参考值:

or check if the data contains all of the reference values like this:

found = True
For s In Array("2w", "fr", "5k", "2j", "0w")
    If Not data.Exists(s) Then
        found = False
        Exit For
    End If
Next
