AutoIT: Missing Wend for While

All,

Below is the code that I have written in AutoIT.

    $fileToWrite = FileOpen("C:\output.txt", 1)

If FileExists("C:\test.csv") Then
    $fileHandle= FileOpen("test.csv", 0)
    If ($fileHandle = -1) Then
        MsgBox (0, "Error", "Error occured while reading the file")
        Exit
    Else
        While 1
            $currentLine = FileReadLine($fileHandle)
            If @error = -1 Then ExitLoop
            $days = StringSplit($currentLine, ",")
            FileWrite($fileToWrite,$days[2] & ", " & $days[9] & @CRLF)
            EndIf
        Wend
    EndIf
Else
    MsgBox (0, "Error", "Input file does not exist")
EndIf

FileClose($fileToWrite)
FileClose($fileHandle)

And the set of error:

C:\ReadCSV.au3(14,4) : ERROR: missing Wend.
            EndIf
            ^
C:\ReadCSV.au3(9,3) : REF: missing Wend.
        While
        ^
C:\ReadCSV.au3(15,3) : ERROR: missing EndIf.
        Wend
        ^
C:\ReadCSV.au3(3,34) : REF: missing EndIf.
If FileExists("C:\test开发者_运维百科.csv") Then
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^
C:\ReadCSV.au3(15,3) : ERROR: syntax error
        Wend
        ^
C:\ReadCSV.au3 - 3 error(s), 0 warning(s)
>Exit code: 0    Time: 3.601

I am not able to understand the issue here since I do have a Wend and EndIf for every While loop and an If condition. Am I missing something here?

Since you have the command ExitLoop after the then, there is no need for the EndIf.

(In this line: If @error = -1 Then ExitLoop)

You could either:

1. Remove the EndIf

   While 1
       $currentLine = FileReadLine($fileHandle)
       If @error = -1 Then ExitLoop
       $days = StringSplit($currentLine, ",")
       FileWrite($fileToWrite,$days[2] & ", " & $days[9] & @CRLF)
   Wend
   

2. Move the ExitLoop to the next line. (Which doesn't make a whole lot of sense, but the script will still run.)

   While 1
       $currentLine = FileReadLine($fileHandle)
       If @error = -1 Then
       ExitLoop
       $days = StringSplit($currentLine, ",")
       FileWrite($fileToWrite,$days[2] & ", " & $days[9] & @CRLF)
       EndIf
   Wend
   

I would go with #1.

The problem is that you have a Endif before the Wend and the If is already closed because you have ExitLoop over there.

So either remove the Endif or put the ExitLoop somewhere else.
