Exchange Web服务 - 如何加载MIME内容类型PoEprty项目附件

Question

我正在尝试运行以下代码的tghe来编写一个物品，该项目是磁盘上文件的电子邮件附件，但它会产生错误，因为它不会加载属性。

using (Stream FileToDisk = new FileStream(emailAttachmentsPath, FileMode.OpenOrCreate, FileAccess.ReadWrite))
{
    itemAttachment.Load(
    byte[] ContentBytes = System.Convert.FromBase64String(itemAttachment.ContentType);

    FileToDisk.Write(ContentBytes, 0,ContentBytes.Length);
    FileToDisk.Flush();
    FileToDisk.Close();
} 

.

我已经尝试过，但它不会编译：

email.Load(new PropertySet(ItemSchema.MimeContent));

.

如何获取项目内容类型，以便我可以创建我的ContentBytes对象？

Answer 1

最后我这样做了（基本上我需要加载 ietem 附件的mimi内容，加上一些额外的属性：

itemAttachment.Load(new PropertySet(BasePropertySet.FirstClassProperties));

itemAttachment.Load(new PropertySet(
        BasePropertySet.IdOnly,
        ItemSchema.Subject,
        ItemSchema.DateTimeReceived,
        ItemSchema.DisplayTo, 
        EmailMessageSchema.From, EmailMessageSchema.Sender,
        EmailMessageSchema.HasAttachments, ItemSchema.MimeContent,
        EmailMessageSchema.Body, EmailMessageSchema.Sender,
        ItemSchema.Body) { RequestedBodyType = BodyType.Text });

string BodyText = itemAttachment.Item.Body.Text;

string itemAttachmentName = itemAttachment.Name.Replace(":", "");

// Put attachment contents into a stream. 
emailAttachmentsPath = emailAttachmentsPath + "\\" + itemAttachmentName +  ".eml";
var mimeContent = itemAttachment.Item.MimeContent;

//save to disk 
using (var fileStream = new FileStream(emailAttachmentsPath, FileMode.Create))
{
    fileStream.Write(mimeContent.Content, 0, mimeContent.Content.Length);
}

.

另一个选项：

var mimeContent2 = itemAttachment.Item.MimeContent;
byte[] ContentBytes = mimeContent2.Content;

//convert array of bytes into file
FileStream objfileStream = new FileStream("C:\\email2case\\temp\\testing" + System.DateTime.Now.ToString("HHmmss") + ".eml", FileMode.Create);
objfileStream.Write(ContentBytes, 0, ContentBytes.Length);
objfileStream.Close();

.

我希望这有助于某人！

itemAttachment.Load(new PropertySet(EmailMessageSchema.MimeContent));
var mimeContent2 = itemAttachment.Item.MimeContent;
fileBytes = mimeContent2.Content;
