c# - 如何在 PowerShell 中创建一个 Outlook 规则，将电子邮件无错误地移动到文件夹，使用在 C# 中完美运行的相同代码？

Question

我正在尝试编写 PowerShell 代码来创建 Outlook 规则来移动电子邮件，但它不起作用。

请注意，我无权访问服务器，因此 *-InboxRule cmdlet(如 New-InboxRule)不可用。

PowerShell 和 Outlook 之间的 COM 互操作发生了一些奇怪的事情，因为它在 C# 中完美运行，但相同的代码在 PowerShell 中却不行。

这是 C# 代码，完美:

Microsoft.Office.Interop.Outlook.Application outlook = null;

try
{
    outlook = (Microsoft.Office.Interop.Outlook.Application)System.Runtime.InteropServices.Marshal.GetActiveObject("Outlook.Application");
}
catch
{
}

if (outlook == null)
{
    outlook = new Microsoft.Office.Interop.Outlook.Application();
}

var inbox = outlook.Application.Session.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderInbox);
var oMoveTarget = inbox.Folders["MoveTarget"];

// debugging
Console.WriteLine(inbox.FolderPath.ToString());
Console.WriteLine(oMoveTarget.FolderPath.ToString());

var rules = outlook.Session.DefaultStore.GetRules();
Console.WriteLine(string.Format("There are {0} rules", rules.Count));

var name = string.Format("Rule {0}", DateTime.Now.ToString("yyyyMMdd_HHmmss"));
var rule = rules.Create(name, Microsoft.Office.Interop.Outlook.OlRuleType.olRuleReceive);

// conditions
rule.Conditions.From.Recipients.Add("John Smith");
rule.Conditions.From.Recipients.ResolveAll();
rule.Conditions.From.Enabled = true;

// actions
rule.Actions.MoveToFolder.Folder = oMoveTarget;
rule.Actions.MoveToFolder.Enabled = true;
rules.Save(true);

现在，这是完全相同(语言语法除外)的 PowerShell 代码:

try
{
    $outlook = [Runtime.InteropServices.Marshal]::GetActiveObject("Outlook.Application");
}
catch
{
}

if ($outlook -eq $null)
{
    $outlook = New-Object -ComObject Outlook.Application
}

$inbox = $outlook.Application.Session.GetDefaultFolder([Microsoft.Office.Interop.Outlook.OlDefaultFolders]::olFolderInbox);
$oMoveTarget = $inbox.Folders["MoveTarget"];

# debugging
[Console]::WriteLine($inbox.FolderPath.ToString());
[Console]::WriteLine($oMoveTarget.FolderPath.ToString());

$rules = $outlook.Session.DefaultStore.GetRules();
[Console]::WriteLine([string]::Format("There are {0} rules", $rules.Count));

$name = [string]::Format("Rule {0}", [DateTime]::Now.ToString("yyyyMMdd_HHmmss"));
$rule = $rules.Create($name, [Microsoft.Office.Interop.Outlook.OlRuleType]::olRuleReceive);

# conditions
$rule.Conditions.From.Recipients.Add("John Smith");
$rule.Conditions.From.Recipients.ResolveAll();
$rule.Conditions.From.Enabled = $true;

# actions
$rule.Actions.MoveToFolder.Folder = $oMoveTarget;
$rule.Actions.MoveToFolder.Enabled = $true;
$rules.Save($true);

虽然 C# 代码成功，但 PS 代码失败:

One or more rules cannot be saved because of invalid actions or conditions.
At line:1 char:1
+ $rules.Save($true);
+ ~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : OperationStopped: (:) [], COMException
    + FullyQualifiedErrorId : System.Runtime.InteropServices.COMException
 

进一步调查，这基本上是由这条线引起的，它实际上没有做任何事情:

$rule.Actions.MoveToFolder.Folder = $oMoveTarget;

当我运行 C# 等效程序时，如果我立即转身查看该属性，它已已设置。但是，在 PowerShell 中，它不会抛出错误或任何东西...它只是默默地什么都不做。

我怎样才能让它发挥作用？请帮忙!

你可以这样做:

# actions
$action = $rule.Actions.MoveToFolder
$action.Enabled = $true

[Microsoft.Office.Interop.Outlook.MoveOrCopyRuleAction].InvokeMember("Folder",[Reflection.BindingFlags]::SetProperty, $null, $action, $oMoveTarget)
