PowerGui - 我如何指定我只想要身體的前100個字符？

Question

如何指定我只想要身體的前100個字符？現在，我收到消息「Warning：column」Body「不適合顯示並被刪除。」

下面是全部代碼：

#connect to outlook 
$GetOutlook = New-Object -com "Outlook.Application"; 
$olName = $GetOutlook.GetNamespace("MAPI") 
$olxEmailFolder = $olName.GetDefaultFolder(‘olFolderInbox’) 
$olxEmailFolder.Name 
$olxEmailItem = $olxemailFolder.items 

#show unread emails in inbox 
$olxEmailItem | select SentOn, SenderName, Subject, Body | Format-Table -auto 

#go through each subfolder and get name 
$SubFolders = $olxEmailFolder.Folders 
ForEach($Folder in $SubFolders) 
{ 
    $Folder.Name 
    $SubfolderItem = $Folder.Items 
    $EmailCount = 1 
#create status bar for each subfolder 
    ForEach($Email in $SubfolderItem) 
    { 
    Do 
    { 
     Write-Progress -Activity "Checking folder" -status $Folder.Name -PercentComplete ($EmailCount/$Folder.Items.Count*100) 
     $EmailCount++ 
    } 
#show unread emails from subfolders 
    While($EmailCount -le $Folders.Item.Count) 
    $Email | select SentOn, SenderName, Subject, Body | Format-Table -Auto 
    } 
} 
#connect to tasks 
$olxTasksFolder = $olName.GetDefaultFolder(‘olFolderTasks’) 
$olxTaskItems = $olxTasksFolder.items 
$TaskCount = 1 
#create task array 
$TaskList = @() 
ForEach($TaskItem in $olxTaskItems) 
{ 
#create status bar for tasks 
    Do 
    { 
    Write-Progress -Activity "Checking" -status "Tasks" -PercentComplete ($Taskcount/ 

$olxTasksFolder.Items.count*100) 
    $TaskCount++ 
    } 
#add each incomplete tash to array 
    While($TaskCount -le $olxTaskFolder.Items.Count) 
    If($TaskItem.Complete -eq $False) 
    { 
    $TaskList+=New-Object -TypeName PSObject -Property @{ 
    Subject=$TaskItem.Subject 
    DateCreated=$TaskItem.CreationTime 
    Percent=$TaskItem.PercentComplete 
    Due=$TaskItem.DueDate 
    }} 
} 
#show task array to screen 
$TaskList | Sort DueDate -descending | Format-Table -Auto

可以使用calculated property。

例如，替換：

select Body 

隨着：

select @{n='BodySubstring';e={$_.Body.Substring(0,100)}}
