在C＃asp.net中發送電子郵件時出錯

Question

我已經開始構建我的“聯系我們”頁面，該頁面使用Outlook Interop發送電子郵件。 它引發以下異常：

System.UnauthorizedAccessException: Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} 
failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).

nonPublic) at System.Activator.CreateInstance(Type type) at 
OnlinePayslip.Forms.Support.sendEMailThroughOUTLOOK() in D:\OnlinePayslip\OnlinePayslip\OnlinePayslip\Forms\Support.aspx.cs:line 42

我的代碼是：

using Outlook = Microsoft.Office.Interop.Outlook;
using System.Net.Mail;

public void sendEMail()
{
    try
    {
        // Create the Outlook application.
        Outlook.Application oApp = new Outlook.Application();

        // Create a new mail item.
        Outlook.MailItem oMsg = (Outlook.MailItem)oApp.CreateItem(Outlook.OlItemType.olMailItem);

        // Set HTMLBody. 
        //add the body of the email
        oMsg.HTMLBody = txtEmailBody.Text + "</br> From " + Session["User"].ToString();
        int iPosition = (int)oMsg.Body.Length + 1;               
        oMsg.Subject = "Email Alert";
        Outlook.Recipients oRecips = (Outlook.Recipients)oMsg.Recipients;
        Outlook.Recipient oRecip = (Outlook.Recipient)oRecips.Add("kim@npc.com.sa");
        oRecip.Resolve();
        oMsg.Send();                   
        oRecip = null;
        oRecips = null;
        oMsg = null;
        oApp = null;
        lblMsg.Text = "Email Sent";
    }
    catch (Exception ex)
    {
        lblMsg.Text = ex.ToString();
    }
}

您能幫助我理解Access is denied / UnauthorizedAccessException以及如何解決嗎？

您可以只使用MailMessage類。 我舉一個例子。

創建一個類，然后將其稱為MailHelper。 然后粘貼此代碼。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Net.Mail;
using System.Net;

namespace SampleEMailSender
{
    public class MailHelper
    {

        public void SendingEmail(string subject, string body) {

            MailMessage mailMessage = new MailMessage();
            mailMessage.To.Add("<email to send>");
            mailMessage.From = new MailAddress("<email to use in sending>");
            mailMessage.Subject = subject; //the email subject
            mailMessage.Body = body; //the email body
            SmtpClient smtpClient = new SmtpClient("smtp.gmail.com", 587);
            smtpClient.EnableSsl = true;
            smtpClient.UseDefaultCredentials = false;
            smtpClient.Credentials = new NetworkCredential("<gmail account>", "<gmail password>");
            smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
            smtpClient.Send(mailMessage);
        }
    }
}

如您所見，在smtpClient.Credentials和smtpClient ，我使用了一個GMail帳戶。 這是因為它們提供了用於發送電子郵件的免費端口。 它是免費的，不用擔心。

現在，您可以從主頁上調用該類。

MailHelper m = new MailHelper();

m.SendingEmail(<subject>, <body>);

就是這樣。 這就是您如何通過C＃代碼發送電子郵件的方法。
