我的查詢通過Outlook使用C發送電子郵件時發生了什麼問題＃

Question

下面的圖像是我的問題Application。我試着添加

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

，但沒有任何變化

我加了命名空間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

這行代碼是尋找所謂Application類級別領域，我認爲不存在：

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

在方法內部創建的Application一個實例（像你說你做），然後從上面的代碼中刪除關鍵字this：

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

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

如果您需要訪問Application之外的方法，然後創建Application在類級別（任何方法之外），並在構造函數內實例化它（如果這適合您的情況）。
