Question

我使用MailMessage功能从我的winforms应用程序发送电子邮件。

我编译电子邮件，将其保存到磁盘，然后默认邮件客户端将打开邮件，以便用户在点击发送之前验证设置。

我想设置＆＃39; From＆＃39;电子邮件自动发送到邮件客户端中设置的默认电子邮件帐户。我怎么能这样做？

var mailMessage = new MailMessage();
mailMessage.From = new MailAddress(fromEmailAccount);
mailMessage.To.Add(new MailAddress("recipient@work.com"));
mailMessage.Subject = "Mail Subject";
mailMessage.Body = "Mail Body";

如果我将fromEmailAccount留空，我会收到错误，如果我将其设置为＆＃39; test@test.com'由于本地帐户无权通过未知帐户发送电子邮件，因此电子邮件不会发送。

Answer 1

从操作系统中获取用户信息（如果是Windows 8,10），他们将用户设置为用户电子邮件，请参阅此问题：Get user information in Windows 8?

我已经测试了以下代码，这似乎从地址获取本地默认邮件并启动邮件消息窗口，希望它有所帮助：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Outlook = Microsoft.Office.Interop.Outlook;

namespace testMailEmailUser
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Outlook.Application application = new Outlook.Application();
            Outlook.AddressEntry mailSender = null;

            Outlook.Accounts accounts = application.Session.Accounts;

            foreach (Outlook.Account account in accounts)
            {
                mailSender = account.CurrentUser.AddressEntry;
            }

            Outlook.MailItem mail =
                application.CreateItem(
                Outlook.OlItemType.olMailItem)
                as Outlook.MailItem;

            if (mailSender != null)
            {
                mail.To = "someone@example.com; another@example.com";
                mail.Subject = "Some Subject Matter";
                mail.Body = "Some Body Text";
                mail.Sender = mailSender;
                mail.Display(false);
            }
        }

    }
}
