FileExists 方法

如果指定的檔案存在，則傳回 True；如果不存在，則傳回 False。

語法

object.FileExists(filespec)

引數：

• Object：必要。一律是 FileSystemObject 的名稱。
• Filespec：必要。要判斷檔案是否存在的檔案絕對路徑。

下列範例說明 FileExists 方法的用法。

範例 1：

Function CheckFileExists(filespec)
    Dim fso, msg
    Set fso = CreateObject("Scripting.FileSystemObject")
    If (fso.FileExists(filespec)) Then
        msg = filespec & " exists."
    Else
        msg = filespec & " doesn't exist."
    End If
    CheckFileExists = msg
End Function

' Sample usage
Dim result
result = CheckFileExists("C:\example.txt")
' Outputs: C:\example.txt exists. or C:\example.txt doesn't exist.

範例 2：

Function CheckMultipleFiles(files)
    Dim fso, file, result
    Set fso = CreateObject("Scripting.FileSystemObject")
    For Each file In files
        If fso.FileExists(file) Then
            result = result & file & " exists."
        Else
            result = result & file & " doesn't exist."
        End If
    Next
    CheckMultipleFiles = result
End Function

' Sample usage
Dim filesToCheck, checkResult
filesToCheck = Array("C:\file1.txt", "C:\file2.txt", "D:\file3.txt")
checkResult = CheckMultipleFiles(filesToCheck)
' Outputs the existence status of each file in the array.
