如何检索Outlook联系人的图片

Question

Microsoft.Office.Interop.Outlook.Items OutlookItems;
Microsoft.Office.Interop.Outlook.Application outlookObj = new Microsoft.Office.Interop.Outlook.Application();
MAPIFolder Folder_Contacts;
Folder_Contacts = (MAPIFolder)outlookObj.Session.GetDefaultFolder(OlDefaultFolders.olFolderContacts);
OutlookItems = Folder_Contacts.Items;

for (int i = 0; i < OutlookItems.Count; i++)
{
    Microsoft.Office.Interop.Outlook.ContactItem contact = (Microsoft.Office.Interop.Outlook.ContactItem)OutlookItems[i + 1];

    bool to = contact.HasPicture; //returns false although there is a picture in Outlook.
    string h = contact.FirstName; //returns my first name
}

为什么上面的代码无法看到图片，但可以拉出名字，我怎样才能得到图片。

错误：

Answer 1

Attachment.GetTemporaryFilePath Method (Outlook)

var attachment = contact.Attachments["ContactPicture.jpg"] as Attachment;
var path = attachment.GetTemporaryFilePath();

Attachment.SaveAsFile Method (Outlook)

var attachment = contact.Attachments["ContactPicture.jpg"] as Attachment;
attachment.SaveAsFile(savePath);

请注意，此处的“路径”包括文件名，而不仅仅是目录。

示例：

var savePath = @"C:\Users\User\Documents\OutlookPhotos\YourDesiredFileName.jpg";

修改

这是一种方法。它为你处理空值。

static void WriteOutlookContactPhotoToFile(ContactItem contact, string directory, string fileName)
{
    if (contact != null && contact.HasPicture)
    {
        var attachment = contact.Attachments["ContactPicture.jpg"] as Attachment;
        if (attachment != null)
        {
            string writePath = Path.Combine(directory, fileName);
            attachment.SaveAsFile(writePath);
        }
    }
}

Answer 2

在上面的屏幕截图中，ContactItem.HasPicture == false，表示没有图片。不保证附件存在。你需要检查null（attachment！= null）。
