使用C＃創建新電子郵件並附加文件Outlook 2016

Question

我有一份文件清單和電子郵件地址。

我正在嘗試創建一種可用於迭代拋出emailAddresses列表的方法，並為每個Outlook創建新電子郵件並附加相應的文檔。

創建MailItem是我被卡住了。 在MSDN上找到了一個示例，該示例應可從Office 2013開始使用。

這是我到目前為止的內容：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Office.Interop.Outlook;

namespace Test_Invoice
{
    class SendviaMail
    {
        string demofile = @"C:\Desktop\test-inv\1_Test Testesen_1_010.pdf";
        public void Send()
        {
            MailItem eMail = new MailItem();

            eMail.Subject = "Here is Your Invoice";
            eMail.To = "test@testesen.dk";
            eMail.Body = "Dette er en test mail for TestMailApp";

        }

        public void Send(string email, string filename)
        {

        }
    }
}

我一直在嘗試了解MSDN上的文檔，並在此處閱讀一些文章。

據我所知，下一步是添加附件（演示文件），如果我理解正確的話，我需要

eMail.AttachmentAdd = demofile;

但這不起作用。

可能是我無法正確理解庫。 從MSDN https://msdn.microsoft.com/zh-cn/library/bb644320.aspx看此示例

此代碼中的結果：

using Microsoft.Office.Interop.Outlook;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Outlook = Microsoft.Office.Interop.Outlook;

namespace Test_Invoice
{
    class SendviaMail
    {
        string demofile = @"C:\Desktop\test-inv\1_Test Testesen_1_010.pdf";
        public void Send()
        {
            Outlook.MailItem mail = Application.CreateItem(Outlook.OlItemType.olMailItem) as Outlook.MailItem;
            mail.Subject = "Quarterly Sales Report FY06 Q4";

            //MailItem eMail = new MailItem();

            //eMail.Subject = "tilmelding og faktura";
            //eMail.To = "test@testesen.dk";
            //eMail.Body = "Dette er en test mail for TestMailApp";
            //eMail.AttachmentAdd
        }

        public void Send(string email, string filename)
        {

        }
    }
}

為此使用.Net類：

public static void CreateMessageWithAttachment(string server,string filePath)
{
    // Specify the file to be attached and sent.
    // This example assumes that a file named Data.xls exists in the
    // current working directory.
    string file = filePath;
    // Create a message and set up the recipients.
    MailMessage message = new MailMessage(
       "jane@contoso.com",
       "ben@contoso.com",
       "Quarterly data report.",
       "See the attached spreadsheet.");

    // Create  the file attachment for this e-mail message.
    Attachment data = new Attachment(file, MediaTypeNames.Application.Octet);
    // Add time stamp information for the file.
    ContentDisposition disposition = data.ContentDisposition;
    disposition.CreationDate = System.IO.File.GetCreationTime(file);
    disposition.ModificationDate = System.IO.File.GetLastWriteTime(file);
    disposition.ReadDate = System.IO.File.GetLastAccessTime(file);
    // Add the file attachment to this e-mail message.
    message.Attachments.Add(data);

    //Send the message.
    SmtpClient client = new SmtpClient(server);
    // Add credentials if the SMTP server requires them.
    client.Credentials = CredentialCache.DefaultNetworkCredentials;

    try {
      client.Send(message);
    }
    catch (Exception ex) {
      Console.WriteLine("Exception caught in CreateMessageWithAttachment(): {0}", 
                  ex.ToString() );            
    }
    data.Dispose();
}

之后，只需循環訪問列表並將其發送到函數

Answer 2

固定的示例代碼應如下所示：

var ol = new Outlook.Application();
Outlook.MailItem mail = ol.CreateItem(Outlook.OlItemType.olMailItem) as Outlook.MailItem;

請注意，您需要using語句聲明Outlook別名：

using Outlook = Microsoft.Office.Interop.Outlook;

（就像您已經做過的一樣）...但也必須刪除

using Microsoft.Office.Interop.Outlook;

為了避免Visual Studio混淆您的引用。

MSDN示例的其余部分應該可以按預期運行，因為我沒有其他可以指向您的示例，因此，最好的選擇是搜索Microsoft.Office.Interop.Outlook或在此處探索鏈接的問題。
