使用C＃通过Outlook发送电子邮件的查询出了什么问题

Question

如下图所示是Application的问题。我试图添加

Outlook.Application Application = new Outlook.Application();

但没有任何改变

我将名称空间添加为using Outlook = Microsoft.Office.Interop.Outlook;

    #region Send Email
    private void SendEmail()
    {
        string subjectEmail = "Meeting has been rescheduled.";
        string bodyEmail = "Meeting is one hour later.";
        Outlook.MAPIFolder sentContacts = (Outlook.MAPIFolder)
            this.Application.ActiveExplorer().Session.GetDefaultFolder
            (Outlook.OlDefaultFolders.olFolderContacts);
        foreach (Outlook.ContactItem contact in sentContacts.Items)
        {
            if (contact.Email1Address.Contains("example.com"))
            {
                this.CreateEmailItem(subjectEmail, contact
                    .Email1Address, bodyEmail);
            }
        }
    }

    private void CreateEmailItem(string subjectEmail, string toEmail, string bodyEmail)
    {
        Outlook.Application Application = new Outlook.Application();
        Outlook.MailItem eMail = (Outlook.MailItem)
            this.Application.CreateItem(Outlook.OlItemType.olMailItem);
        eMail.Subject = subjectEmail;
        eMail.To = toEmail;
        eMail.Body = bodyEmail;
        eMail.Importance = Outlook.OlImportance.olImportanceLow;
        ((Outlook._MailItem)eMail).Send();
    }
    #endregion

这行代码正在寻找一个名为Application的类级别字段，我认为该字段不存在：

Outlook.MAPIFolder sentContacts = (Outlook.MAPIFolder)
    this.Application.ActiveExplorer().Session.GetDefaultFolder
        (Outlook.OlDefaultFolders.olFolderContacts);

在方法中创建Application的实例（就像你说的那样），然后从上面的代码中删除关键字this：

Outlook.Application Application = new Outlook.Application();

Outlook.MAPIFolder sentContacts = (Outlook.MAPIFolder)
    Application.ActiveExplorer().Session.GetDefaultFolder
        (Outlook.OlDefaultFolders.olFolderContacts);

如果您需要访问该方法之外的Application，那么在类级别（在任何方法之外）创建Application并在构造函数内实例化它（如果这适合您的情况）。
