EMS Powershell V2 如何附加到 CSV

Question

我是 Powershell 的新手，所以请多多包涵。

我正在尝试编写一个 powershell 脚本，该脚本将扫描 Exchange 2010 中的多个邮箱并将最后收到的日期写入现有的 CSV 文件。由于服务器是运行ning Exchange 2010，它有 PowerShell v2，所以我不能使用 PS v3 中可用的 -Append 参数，所以我尝试使用 out-file 和 Add-Content，但是两者都失败，并在脚本的第二个运行中出现下面列出的错误。我假设我在导入或写入现有 CSV 文件时做错了什么，但我无法弄清楚到底是什么。

# Path to the CSV file. This needs to be in place before the scrpt runs

$results = Import-CSV -Path 'C:\temp\numberofmails.csv' -Header "Mailbox","TotalItems","LastReceived",
    
# go through the mabList array and get the identity, number of items and last received date and time
    
Foreach($i in $mbxList){

$data = Get-MailboxFolderStatistics -Identity $i -IncludeOldestAndNewestItems | Where {$_.Name -match "Inbox"} |select identity,ItemsInFolder,NewestItemReceivedDate

$mbID=$data.identity

$numItems=$data.ItemsInFolder

$lastReceived=$data.NewestItemReceivedDate

#Append data to the CSV file using PS v2 so cannot use append as can be done in v3

$exp = $results

$exp.Mailbox = $mbID

$exp.TotalItems = $numItems

$exp.LastReceived = $LastReceived

 
#$exp | ConvertTo-CSV -NoTypeInformation | Select-Object -Skip 1| Out-File -Append 'C:\temp\numberofmails.csv'

$exp | ConvertTo-CSV -NoTypeInformation | Select-Object -Skip 1|  Add-Content 'C:\temp\numberofmails.csv' -Encoding UTF8
}

脚本的第二个运行收到错误。

Property 'Mailbox' cannot be found on this object; make sure it exists and is settable.

At C:\Temp\ReceivedItemsv2.ps1:29 char:6

+ $exp. <<<< Mailbox = $mbID

    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException

    + FullyQualifiedErrorId : PropertyAssignmentException

 

Property 'TotalItems' cannot be found on this object; make sure it exists and is settable.

At C:\Temp\ReceivedItemsv2.ps1:30 char:6

+ $exp. <<<< TotalItems = $numItems

    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException

    + FullyQualifiedErrorId : PropertyAssignmentException

 

Property 'LastReceived' cannot be found on this object; make sure it exists and is settable.

At C:\Temp\ReceivedItemsv2.ps1:31 char:6

+ $exp. <<<< LastReceived = $LastReceived
+ CategoryInfo          : InvalidOperation: (:) [], RuntimeException

+ FullyQualifiedErrorId : PropertyAssignmentException

Answer 1

$results 是具有 Mailbox、TotalItems 和 LastReceived 属性的对象集合。您可以选择向该集合添加一个新对象，也可以过滤其中一个对象并更改其属性值。您似乎想要创建一个新对象，将其转换为 CSV，并将其附加到文本文件中。

# Run this code inside of the foreach loop
# Create new object with desired properties
$exp = "" | Select-Object Mailbox,TotalItems,LastReceived

# Set property values
$exp.Mailbox = $mbID
$exp.TotalItems = $numItems
$exp.LastReceived = $LastReceived

# Append object to CSV file
$exp | ConvertTo-CSV -NoTypeInformation |
    Select-Object -Skip 1 |
        Add-Content 'C:\temp\numberofmails.csv' -Encoding UTF8
