我创建了一个使用 C# 发送电子邮件的简单程序。现在我想修改它以一次发送一封电子邮件。

这是我现在拥有的代码,但它不起作用。

using System;

using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.Net.Mail;
using System.Net.Configuration;
using System.Net.NetworkInformation;
using System.Web;
using System.Threading.Tasks;


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

        //Mail properties
        private void button1_Click(object sender, EventArgs e)
        {

            string[] array = { "mail1@mail.com", "mail2@mail.com" };

            foreach (string value in array)
            {

            SmtpClient client = new SmtpClient(comboBox1.Text, 25);
            client.Credentials = new NetworkCredential(textBox1.Text, textBox2.Text);
            MailMessage msg = new MailMessage();
            msg.From = new MailAddress(textBox1.Text);
            msg.To.Add(new MailAddress(value));
            //msg.To.Add(new MailAddress(textBox3.Text));
            msg.Subject = textBox4.Text;
            msg.Priority = MailPriority.Normal;
            msg.IsBodyHtml = false;

            if (checkBox2.Checked)
            {
                msg.IsBodyHtml = true;
            }            
            msg.Body = richTextBox1.Text;

            if (checkBox1.Checked)
            {
                client.Send(textBox1.Text, textBox1.Text, textBox4.Text, richTextBox1.Text);
            }

            //Send mail
            try
            {
                client.Send(msg);
                progressBar1.Increment(100);
            }

            catch (SmtpException)
            {
                MessageBox.Show("Error", "Error", MessageBoxButtons.OK, MessageBoxIcon.Information);
            }
        }
      }

    }
}

谁能帮我解决这个问题?谢谢 :)
