如果語句條件不符合，代碼仍在執行

Question

我正在編寫一個VBScript，它在Active Directory中搜索計算機對象。如果該對象不存在或存在且位於正確的OU中，則它應該運行一個單獨的腳本來創建/將計算機連接到AD。

ObjExist_CorrectOU_7 = Null 
ObjExist_CorrectOU_10 = Null 

If compare = True Then 
    Win7_OU = "OU=DisallowRDP,OU=64Bit,OU=Win8" 
    Win10_OU = "OU=DisallowRDP,OU=64Bit,OU=Win10" 

    For x = 16 To 46 
    If Asc(Mid(objRS.Fields("distinguishedName"), x, 1)) = Asc(Mid(Win7_OU, (x - 15), 1)) Then 
     ObjExist_CorrectOU_7 = True 
    Else 
     ObjExist_CorrectOU_7 = False 
    End If 
    Next 

    For y = 16 To 46 
    If Asc(Mid(objRS.Fields("distinguishedName"), y, 1)) = Asc(Mid(Win10_OU, (y - 15), 1)) Then 
     ObjExist_CorrectOU_10 = True 
    Else 
     ObjExist_CorrectOU_10 = False 
    End If 
    Next 
End If 

If ObjExist_CorrectOU_7 = True Then 
    WScript.Echo "TRUE" 
End If 

Dim objShell 

Set objShell = WScript.CreateObject("WScript.Shell") 

filename = "C:\programdata\dell\kace\k2000_deployment_info.conf" 
Win7_Deployment = "deployment_name=Windows 7 x64 with SP1, join AD" 
Win10_Deployment = "deployment_name=Development Windows 10 (x64), join AD" 

Set fso = CreateObject("Scripting.FileSystemObject") 
Set f = fso.OpenTextFile(filename) 

Do While Not f.AtEndOfStream 
    If ((f.ReadLine = Win7_Deployment) Or ((f.ReadLine = Win7_Deployment) And (ObjExist_CorrectOU_7 = True))) Then 
    WScript.Echo "IT WORKED!" 
    'objShell.Run "JoinAD_Win7.vbs" 
    Exit Do 
    End If 
    On Error Resume Next 
Loop 

f.Close 
Set g = fso.OpenTextFile(filename) 

Do While Not f.AtEndOfStream 
    If ((g.ReadLine = Win10_Deployment) Or ((g.ReadLine = Win10_Deployment) And (ObjExist_CorrectOU_10 = True))) Then 
    'objShell.Run "JoinAD_Win10.vbs" 
    WScript.Echo "IT WORKED AGAIN!" 
    Exit Do 
    End If 
    On Error Resume Next 
Loop 

g.Close 

Set objShell = Nothing 

我遇到的問題是，這兩個If..Then語句執行每一次，儘管我知道絕對沒有得到滿足的條件。

這與我使用Or和And有什麼關係？

您的問題不符合Minimal, Complete, and Verifiable example標準。
然而，乍一看：讀取On Error Statement和ReadLine Method和Working with Files文件。

Do While Not f.AtEndOfStream 
    ''' ↓ this `ReadLine` reads every uneven line i.e. the 1st, 3rd, 5th, … 
    If ((f.ReadLine = Win7_Deployment) Or ((f.ReadLine = Win7_Deployment) And (ObjExist_CorrectOU_7 = True))) Then 
    '''  this one reads every even line ↑  i.e. the 2nd, 4th, 6th, … 
    WScript.Echo "IT WORKED!" 
    'objShell.Run "JoinAD_Win7.vbs" 
    Exit Do 
    End If 
    On Error Resume Next ' this causes that script continues on line next to IF … THEN 
         ' in case of uneven records in file. 
         ' i.e. runtimme error "Input past end of file" 
Loop 

使用類似

Do While Not f.AtEndOfStream 
    sReadLine = f.ReadLine 
    If ((sReadLine = Win7_Deployment) Or ((sReadLine = Win7_Deployment) And (ObjExist_CorrectOU_7 = True))) Then 
    WScript.Echo "IT WORKED!" 
    'objShell.Run "JoinAD_Win7.vbs" 
    Exit Do 
    End If 
    ''' get rid of `On Error Resume Next` statement at all 
Loop 

並且怎麼樣Do While Not f.AtEndOfStream跟進g.ReadLine？使用f或g（在兩者中都是相同的TextStream object）...
