Question

使用PowerShell我可以调用Get-MailPublicFolder来检索有关已启用Exchange邮件的公用文件夹的邮件相关信息。

我想用EWS做同样的事情。特别是获取公用文件夹电子邮件地址。

到目前为止，我已设法将Public Folders作为Microsoft.Exchange.WebServices.Data.Folder对象的列表。但我无法在Folder对象上看到返回文件夹电子邮件地址的属性。我检查了ExtendedProperties属性，它是一个空列表。

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
service.UseDefaultCredentials = true;

// Use Autodiscover to set the URL endpoint.
service.AutodiscoverUrl("joe.bloggs@microsoft.com");

Folder rootfolder = Folder.Bind(service, WellKnownFolderName.PublicFoldersRoot);
FolderView folderView = new FolderView(1000);

foreach (Folder folder in rootfolder.FindFolders(folderView))
{
    folder.Load();
    System.Diagnostics.Debug.WriteLine("Folder Name: " + folder.DisplayName);

    if (folder.ExtendedProperties.Count > 0)
    {
        foreach (ExtendedProperty ep in folder.ExtendedProperties)
        {
            System.Diagnostics.Debug.WriteLine(" " + ep.PropertyDefinition.Name + " = " + ep.Value);
        }
    }                    
}

有人可以告诉我一个如何使用EWS做的例子吗？

谢谢

我已将Shay发布的代码转换为C＃，并且有效：）

以下是转换为C＃的代码：

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
service.UseDefaultCredentials = true;

// Use Autodiscover to set the URL endpoint.
service.AutodiscoverUrl("joe.bloggs@microsoft.com");

Folder rootfolder = Folder.Bind(service, WellKnownFolderName.PublicFoldersRoot);

FolderView folderView = new FolderView(1000);
ExtendedPropertyDefinition proxyProp = new ExtendedPropertyDefinition(26397, MapiPropertyType.Binary);
folderView.PropertySet = new PropertySet(proxyProp);

foreach (Folder folder in rootfolder.FindFolders(folderView))
{
    object objectGuid;
    if (folder.TryGetProperty(proxyProp, out objectGuid))
    {
        objectGuid = System.BitConverter.ToString((byte[])objectGuid).Replace("-", "");
        var adFolder = new DirectoryEntry(string.Format("LDAP://<GUID={0}>", objectGuid.ToString()));
        var mailVal = adFolder.Properties["Mail"].Value;
    }
}

我能够通过以下方式获得它，您需要将其翻译为c＃。结果是使用Email属性扩展的文件夹对象。

$PR_PF_PROXY = New-Object Microsoft.Exchange.WebServices.Data.ExtendedPropertyDefinition 26397,[Microsoft.Exchange.WebServices.Data.MapiPropertyType]::Binary
$view.PropertySet.Add($PR_PF_PROXY) 

$foldersResult = $ExchangeService.FindFolders(Microsoft.Exchange.WebServices.Data.WellKnownFolderName]::PublicFoldersRoot,$view)

    foreach($folder in $foldersResult.Folders)
    {  
        $folder = $folder | Add-Member -MemberType NoteProperty -Name Email -Value $null -PassThru

        $guid=$null
        if($folder.TryGetProperty($PR_PF_PROXY,[ref]$guid))
        {
            $dn=[bitconverter]::ToString($guid) -replace '-'
            $folder.Email = ([ADSI]"LDAP://<GUID=$dn>").Properties.mail.value
        }

        $folder
    }
