Question

我想使用c＃和outlook发送自动电子邮件。我很困惑如何实际发送电子邮件，我认为.Send（）方法将执行此但没有任何反应，当我运行这个，我没有得到任何编译错误。

有谁知道如何激活/执行此代码或知道某处我搞砸了。谢谢。

您可以使用SMTP来执行此操作

using System.Net;
using System.Net.Mail;
using System.Configuration;

static void Main(string[] args)
{
   SendEmail("Lukeriggz@gmail.com", "This is a Test email", "This is where the Body of the Email goes");
}

public static void SendEmail(string sTo, string subject, string body)
{
    var Port = int.Parse(ConfigurationManager.AppSettings["SmtpPort"]);
    using (var client = new SmtpClient(Your EmailHost, Port))
    using (var message = new MailMessage()
    {
        From = new MailAddress(FromEmail),
        Subject = subject,
        Body = body
    })
    {
        message.To.Add(sTo);
        client.DeliveryMethod = SmtpDeliveryMethod.Network;
        client.Credentials = new NetworkCredential(ConfigurationManager.AppSettings["EmailCredential"],
                ConfigurationManager.AppSettings["EmailPassword"]);
        client.EnableSsl = true;
        client.Send(message);
    };
}

如果您希望联系人列表发送相同的电子邮件，请创建List<string>并使用foreach循环将其添加到代码的message.To.Add(sTo)部分..非常直接..

您的问题标题是＆＃34; c＃控制台应用自动发送电子邮件＆＃34;但您似乎使用的是用于Outlook AddIn 的代码。 addin用于在启动addin时调用SendEmail函数，该函数将执行ThisAddIn_Startup：

    private void ThisAddIn_Startup(object sender, System.EventArgs e)
    {
        // this is never executed because it isn't an outlook addin
        SendEmailtoContacts();
    }

    private void SendEmailtoContacts()
    {
       // sends your email... if it actually gets called
    }

请尝试从SendEmailtoContacts()调用Main()函数，因为它是一个控制台应用程序，Main()是运行时实际执行的内容：

        static void Main(string[] args)
        {
            SendEmailtoContacts();
        }

正如我在评论中所指出的那样进一步调试，因为这是Outlook互操作，你应该能够看到这些操作发生在Outlook窗口中，因为它们是在本地桌面上执行的。例如，如果您注释掉最后的((Outlook._MailItem)eMail).Send();行并运行该程序，则应该在程序终止后留下电子邮件，等待您单击“发送”按钮。

看起来您还必须将其他函数的方法签名修改为静态方法，并删除this.CreateEmailItem中的 this 引用？

        public static void SendEmailtoContacts()
        {
            string subjectEmail = "test results ";
            string bodyEmail = "test results";
            Microsoft.Office.Interop.Outlook.Application appp = new  
            Microsoft.Office.Interop.Outlook.Application();
            Microsoft.Office.Interop.Outlook.MAPIFolder sentContacts = 
            appp.ActiveExplorer().Session.GetDefaultFolder(Microsoft.Office.Interop.Outlook.O    lDefaultFolders.olFolderContacts);

            foreach (Outlook.ContactItem contact in sentContacts.Items)
            {
                if (contact.Email1Address.Contains("gmail.com"))
                {
                    CreateEmailItem(subjectEmail, contact.Email1Address, bodyEmail);
                }
            }
        }

        public static void CreateEmailItem(string subjectEmail,string toEmail, string bodyEmail)
        {
            Microsoft.Office.Interop.Outlook.Application app = new  
            Microsoft.Office.Interop.Outlook.Application();
            Microsoft.Office.Interop.Outlook.MailItem eMail = 
            app.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);

            eMail.Subject = subjectEmail;
            eMail.To = toEmail;
            eMail.Body = bodyEmail;
            eMail.Importance = Outlook.OlImportance.olImportanceLow;
            ((Outlook._MailItem)eMail).Send();
        }
