Question

我有以下代码，并且一直在尝试添加IF语句，以便在找不到该项时，写入文本NotFound。

$csv1 = Import-Csv D:\MaintenanceWindow2.csv
$csv2 = Import-Csv D:\ScomAlerts.csv    
$csv1 | Where {$field = $_.Computername;($csv2 | where {$_.Computername -eq $field})}

-Edit，这是我目前所拥有的，但似乎并没有选择每个服务器。

Import-Csv D:\2.csv | ForEach-Object {
    $table[$_.Computername] = $_.'Collection Name'}

$Global:result = $AlertDataNoDupe | ForEach-Object { [PSCustomObject] @{ 

Server=$_.NetbiosComputerName

MaintenanceWindow=IF($table[$_.NetbiosComputerName]){$table[$_.NetbiosComputerName]}

                ELSE{"Not found!"}
}

-Edit，添加样本数据

MaintenanceWindow2.csv：

"Computername","Collection Name"
"Server1","NA - All DA Servers - Patching - Cert - Thu 2:00"
"Server2","NA - All DA Servers - Patching - Cert - Thu 2:00"

ScomAlerts.csv：

ComputerName
Server2
Server3

Answer 1

更新后的问题中的脚本应该可以正常工作。我要做的唯一更改是使用<book/occurrences/promotionNum>并使用缩进，但这主要是为了提高可读性。

$table.ContainsKey("")

或

$MaintenanceWindows = @"
"Computername","Collection Name"
"Server1","NA - All DA Servers - Patching - Cert - Thu 2:00"
"Server2","NA - All DA Servers - Patching - Cert - Thu 2:00"
"@ | ConvertFrom-Csv

$ScomAlerts = @"
ComputerName
Server2
Server3
"@ | ConvertFrom-Csv

#Create hashtable
$table = @{}
#Add MWs to hashtable
$MaintenanceWindows | ForEach-Object { $table.Add(($_.ComputerName.Split(".")[0].Trim()), $_.'Collection Name')}

$Global:result = $ScomAlerts | ForEach-Object {
    $computer = $_.ComputerName.Split(".")[0].Trim()

    [PSCustomObject] @{ 
        Server = $computer
        MaintenanceWindow = if($table.ContainsKey($computer)){
            $table[$computer]
        } else{ "Not found!" }
    }

}

$result

Server  MaintenanceWindow                               
------  -----------------                               
Server2 NA - All DA Servers - Patching - Cert - Thu 2:00
Server3 Not found!

将IF添加到CSV过滤循环中
