Question

我的应用程序需要在Outlook中打开发送电子邮件窗口。

应用程序显示发票列表。当用户点击发票号时，我需要在outlook中打开发送电子邮件窗口并附加PDF语句。然后，用户可以修改该消息并单击“发送”。

我该如何做到这一点？

我尝试了以下内容：

    using Outlook = Microsoft.Office.Interop.Outlook;

该应用程序在开发环境中运行良好，但我得到一个例外：

**System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))**

我没有在应用服务器上安装Outlook。我需要在服务器上进行前景吗？或者例外是出于其他原因？如何摆脱它？

编辑：添加代码

public static void CreateMessageWithAttachment(string invoiceNumber, string recipient, string messageBody )
    {
        try
        {

            Outlook.Application oApp = new Outlook.Application();
            Outlook.MailItem email = (Outlook.MailItem)(oApp.CreateItem(Outlook.OlItemType.olMailItem));

            Models.DYNAMICS_EXTEntities _db = new Models.DYNAMICS_EXTEntities();

            #region set email recipients
            {
                ObjectParameter[] parameters = new ObjectParameter[1];
                parameters[0] = new ObjectParameter("InvoiceNumber", invoiceNumber);

                List<Models.EmailAddress> emailList = _db.ExecuteFunction<Models.EmailAddress>("uspGetEmailAddress", parameters).ToList<Models.EmailAddress>();
                if (emailList.Count() > 0)
                {
                    if(!(string.IsNullOrEmpty(emailList[0].Email.ToString().Trim()) ))
                    recipient = emailList[0].Email.ToString().Trim();

                int iPosition = (int)email.Body.Length + 1;
                int iAttachType = (int)Outlook.OlAttachmentType.olByValue;
                Outlook.Attachment oAttach = email.Attachments.Add(filePath, iAttachType, iPosition, fileName);
            }
            #endregion

            email.Display();                

                        }
        catch (Exception e)
        {
            InvoiceSearchTool.Models.udtExceptionTable exception = new udtExceptionTable();
            exception.MethodName = "email";
            exception.Exception = e.ToString();
            exception.Date = DateTime.Now;
            DYNAMICS_EXTEntities db = new DYNAMICS_EXTEntities();
            db.AddToudtExceptionTables(exception);
            db.SaveChanges();

        }

    }

您必须安装MS Outlook，Office应用程序的COM Interop依赖于Office应用程序可用，Microsoft仍然希望您为您的副本付费，而不是为您提供替换Word，Excel或Outlook的库。

Answer 3

现在我们已经满足了您的实际要求，事情变得更容易了。

首先，从混合中摆脱Outlook。你不需要它。

当用户点击发票号码时，要求他们提供与电子邮件一起发送的消息。一旦他们在使用standard .net smtp objects键入此内容以创建邮件消息，请附加pdf并通过您的邮件服务器发送。

您不需要在服务器上安装Outlook，也不需要任何类型的互操作。

如果您使用的是Exchange或IMAP服务器，则该电子邮件将显示在用户outlook outlook框中。
