C# Outlook 向多个收件人发送一封电子邮件

Question

我一直在尝试弄清楚如何通过 C# 向多个收件人发送 Outlook 电子邮件。现在我可以在收件人之间进行循环，但是我的发件箱中将会有很多已发送的电子邮件。

            Microsoft.Office.Interop.Outlook.Application oApp = new Microsoft.Office.Interop.Outlook.Application();
            Microsoft.Office.Interop.Outlook.MailItem oMsg = (Microsoft.Office.Interop.Outlook.MailItem)oApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);

            oMsg.HTMLBody ="test";
            oMsg.Subject = "test" ;
            Microsoft.Office.Interop.Outlook.Recipients oRecips = (Microsoft.Office.Interop.Outlook.Recipients)oMsg.Recipients;        
            Microsoft.Office.Interop.Outlook.Recipient oRecip = (Microsoft.Office.Interop.Outlook.Recipient)oRecips.Add("xxx@xxx.com");
            oRecip.Resolve();
            oMsg.Send();
            oRecip = null;
            oRecips = null;
            oMsg = null;
            oApp = null;

如果我向其中添加多个地址，例如： (Microsoft.Office.Interop.Outlook.Recipient)oRecips.Add("xxx@xxx.com,yyy@yyy.com,zzz@zzz.com") 这将无法正常工作。谁可以帮我这个事？

您只需用分号分隔每个用户。例如，看看我下面的代码。

Outlook.MailItem mail = null;
 Outlook.Application objApp = new Outlook.Application();               
 mail=(Outlook.MailItem)objApp.CreateItem(Outlook.OlItemType.olMailItem);

  mail.Subject ="HI";
  mail.To = "personone@yahoo.com; Persontwo@yahoo.com";
  mail.Attachments.Add("C:\SOME_FOLDER\SomeFile");
  mail.Body="xxxxxx";
  mail.Send();
