Question

由于某种原因，我的if语句在ForEach语句中没有正常运行。我认为这样做的唯一原因是，如果ForEach语句在$ {Source}声明之后停止，那将是奇怪的。

function new-Backup {
ForEach ($Source in $Sources){
    ${FileName} = Split-Path ${Source} -Leaf

    Add-Content ${Log}\${Timestamp}.log "[Information] $(Get-Timestamp): Backup Script Running..."
    Add-Content ${Log}\${Timestamp}.log "[Information] $(Get-Timestamp): Creating archive: ${FileName}-${TimeStamp}.zip"

    WinRAR a -ep ${Destination}\${FileName}-${TimeStamp}.zip $Source

    If(Test-Path -Path ${Destination}\${Filename}-${Timestamp}){
        Add-Content ${Log}\${Timestamp}.log "[Information] $(Get-Timestamp): Successfully created archive: ${FileName}-${TimeStamp}.zip"
    Else{
        Add-Content ${Log}\${Timestamp}.log "[Information] $(Get-Timestamp): Failed to create archive: ${FileName}-${TimeStamp}.zip"
    }
    }
}

我忘了包含Test-Path命令的文件扩展名，因此总是返回false。我也忘记了if语句的结束括号，它不允许if语句运行。更正的代码已发布在下方。

function new-Backup {
ForEach ($Source in $Sources){
    ${FileName} = Split-Path ${Source} -Leaf

    Add-Content ${Log}\${Timestamp}.log "[Information] $(Get-Timestamp): Backup Script Running..."
    Add-Content ${Log}\${Timestamp}.log "[Information] $(Get-Timestamp): Creating archive: ${FileName}-${TimeStamp}.zip"

    WinRAR a -ep ${Destination}\${FileName}-${TimeStamp}.zip $Source

    If(Test-Path -Path ${Destination}\${Filename}-${Timestamp}.zip){
        Add-Content ${Log}\${Timestamp}.log "[Information] $(Get-Timestamp): Successfully created archive: ${FileName}-${TimeStamp}.zip"
    }Elseif(-Not(Test-Path -Path ${Destination}\${Filename}-${Timestamp}.zip)){
        Add-Content ${Log}\${Timestamp}.log "[Information] $(Get-Timestamp): Failed to create archive: ${FileName}-${TimeStamp}.zip"
    }
}

如果语句未在ForEach中运行
