如何修復錯誤“'的類型初始化程序？' 拋出異常。” 使用 EASendMail 通過 C# 發送電子郵件時？

Question

我一直在從事這個項目以向用戶發送電子郵件，並且一直出現錯誤。 （我正在使用 EASendMail NuGet 包）它是“'的類型初始化程序'？ 拋出異常。” （這是在 package 具有的錯誤系統的控制台中）我真的不知道這意味着什么，我的代碼是這樣的：

using EASendMail;

namespace Email
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                SmtpMail oMail = new SmtpMail("TryIt");

                // Set sender email address, please change it to yours
                oMail.From = "Splat2ooner@gmail.com";
                // Set recipient email address, please change it to yours
                oMail.To = "Splat2ooner@gmail.com";

                // Set email subject
                oMail.Subject = "test email from c# project";
                // Set email body
                oMail.TextBody = "this is a test email sent from c# project, do not reply";

                // SMTP server address
                SmtpServer oServer = new SmtpServer("smtp.gmail.com");

                // User and password for ESMTP authentication
                oServer.User = "Splat2ooner@gmail.com";
                oServer.Password = "password (not my passoword)";

                // Most mordern SMTP servers require SSL/TLS connection now.
                // ConnectTryTLS means if server supports SSL/TLS, SSL/TLS will be used automatically.
                oServer.ConnectType = SmtpConnectType.ConnectTryTLS;

                // If your SMTP server uses 587 port
                //oServer.Port = 587;

                // If your SMTP server requires SSL/TLS connection on 25/587/465 port
                //oServer.Port = 25; // 25 or 587 or 465
                oServer.ConnectType = SmtpConnectType.ConnectSSLAuto;

                Console.WriteLine("start to send email ...");

                SmtpClient oSmtp = new SmtpClient();
                oSmtp.SendMail(oServer, oMail);

                Console.WriteLine("email was sent successfully!");
            }
            catch (Exception ep)
            {
                Console.WriteLine("failed to send email with the following error:");
                Console.WriteLine(ep.Message);
            }
        }
    }
}

謝謝。

看起來較新版本的“ EASendMail ”（截至目前最新版本是7.5.0.3 ）package 有這個問題。

我沒有太多時間研究它，只是安裝了舊版本（ 7.3.1.2 ）並解決了這個問題。

希望能幫助到你。
