先找到指定的信箱和信箱目錄

using Outlook = Microsoft.Office.Interop.Outlook;
private static Outlook.Folder GetMailFolder(Outlook.Application app, string BoxName, string FolderName)
{

    Outlook.Store st = null;
    foreach (Outlook.Store s in app.Session.Stores)
        if (s.DisplayName == BoxName)
            st = s;
    foreach (Outlook.Folder f in st.GetRootFolder().Folders)
        if (f.Name == FolderName)
            return f;
    return null;
}

上列的Method找到的Folder內讀取信件處理

int count = From.Items.Count;
for (int i = count; i > 0; i--)
{
    Outlook.MailItem mail = From.Items[i] as Outlook.MailItem;
    //todo
} 

寫成function:

        public IEnumerable<MailInfo> GetMails(SettingID BoxName, SettingID FolderName)
        {
            var From = GetFolder(BoxName, FolderName);
            int count = From.Items.Count;
            for (int i = count; i > 0; i--)
            {
                if (!(From.Items[i] is Outlook.MailItem mail))
                    From.Items[i].Delete();
                else
                    yield return new MailInfo(mail);
            }
        }

ps. 若想關閉outlook, 宣告的Outlook.Application使用完執行.Quit(), 若不想關就不用執行
