推荐答案

您可以使用C＃使用SMTP服务器。
private void SendBtn_Click（ object sender，System.EventArgs e）
{
// 将光标更改为等待光标
光标cr = Cursor.Current;
Cursor.Current = Cursors.WaitCursor;

// 使用端口25创建服务器SMTP
TcpClient SmtpServ = new TcpClient（ServSMTP.Text， 25 ）;
string 数据;
byte [] szData;
string CRLF = &quo t; \r\\\
" ;
LogList.Items.Clear（）;

try
{
// initialization < br> NetworkStream NetStrm = SmtpServ.GetStream（）;
StreamReader RdStrm = new StreamReader（SmtpServ.GetStream（））;
LogList.Items。添加（RdStrm.ReadLine（））;

// 向服务器问好并将响应发送到日志报告
Data = " HELLO server" + CRLF;
szData = System.Text.Encoding.ASCII.GetBytes（Data.ToCharArray（））;
NetStrm.Write（szData， 0 ，szData.Length）;
LogList.Items.Add（RdStrm.ReadLine（））;
// 发送发件人数据
Data = " MAIL FROM：" + " < span class = code-string><" + sFrom.Text + " >" + CRLF;
szData = System.Text.Encoding.ASCII.GetBytes（Data.ToCharArray（））;
NetStrm.Write（szData， 0 ，szData。长度）;
LogList.Items.Add（RdStrm.ReadLine（））;

// 发送接收者数据
数据= " RCPT TO：" + " < ;" + sTo.Text + " >" + CRLF;
szData = System.Text.Encoding.ASCII.GetBytes（Data.ToCharArray（））;
NetStrm.Write（szData， 0 ，szData.Length）;
LogList。 Items.Add（RdStrm.ReadLine（））;

// 发送数据
数据= " DATA" + CRLF;
szData = System.Text.Encoding.ASCII.GetBytes（Data.ToCharArray （））;
NetStrm.Write（szData， 0 ，szData.Length）;
LogList.Items.Add（RdStrm.ReadLine（））;

// 发送内容数据
数据= " SUBJECT：" + sSubject.Text + CRLF +
sMessage.Text + CRLF + " 。" + CRLF;
szData = System.Text.Encoding.ASCII.GetBytes（Data.ToCharArray（））;
NetStrm.Write（szData，< span class = code-digit> 0 ，szData.Length）;
LogList.Items.Add（RdStrm.ReadLine（））;

// 退出服务器SMTP
数据= " ; QUIT" + CRLF;
szData = System.Text.Encoding.ASCII.GetBytes（Data.ToCharArray（））;
NetStrm。写（szData， 0 ，szData.Length）;
LogList.Items.Add（RdStrm.ReadLine（））;

// close connection
NetStrm.Close（）;
RdStrm.Close（ ）;
LogList.Items.Add（" Close connection" ）;
LogList.Items.Add （" 成功发送邮件.. ）;

// 返回正常光标
Cursor.Current = cr;

}

catch （InvalidOperationException错误）
{
LogList.Items.Add（" 错误：" + err.ToString（））;
}

希望这有所帮助。

You can do this by using SMTP server using C#.
private void SendBtn_Click(object sender, System.EventArgs e)
{
    // change cursor into wait cursor
    Cursor cr = Cursor.Current;
    Cursor.Current = Cursors.WaitCursor;

    // create server SMTP with port 25
    TcpClient SmtpServ = new TcpClient(ServSMTP.Text,25);
    string Data;
    byte[] szData;
    string CRLF = "\r\n";
    LogList.Items.Clear();           

    try
    {
        // initialization
        NetworkStream NetStrm = SmtpServ.GetStream();
        StreamReader  RdStrm= new StreamReader(SmtpServ.GetStream());
        LogList.Items.Add(RdStrm.ReadLine());
           
        // say hello to server and send response into log report
        Data = "HELLO server " + CRLF;               
        szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());
        NetStrm.Write(szData,0,szData.Length);
        LogList.Items.Add(RdStrm.ReadLine());
        // send sender data
        Data = "MAIL FROM: " + "<" + sFrom.Text + ">" + CRLF;
        szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());
        NetStrm.Write(szData,0,szData.Length);
        LogList.Items.Add(RdStrm.ReadLine());

        // send receiver data
        Data = "RCPT TO: " + "<" + sTo.Text + ">" + CRLF;
        szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());
        NetStrm.Write(szData,0,szData.Length);
        LogList.Items.Add(RdStrm.ReadLine());

        // send DATA
        Data = "DATA " + CRLF;
        szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());
        NetStrm.Write(szData,0,szData.Length);
        LogList.Items.Add(RdStrm.ReadLine());               

        // send content data
        Data = "SUBJECT: " + sSubject.Text + CRLF +
           sMessage.Text + CRLF + "." + CRLF;
        szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());
        NetStrm.Write(szData,0,szData.Length);
        LogList.Items.Add(RdStrm.ReadLine());               

        // quit from server SMTP
        Data = "QUIT " + CRLF;
        szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());
        NetStrm.Write(szData,0,szData.Length);
        LogList.Items.Add(RdStrm.ReadLine());               

        // close connection
        NetStrm.Close();
        RdStrm.Close();
        LogList.Items.Add("Close connection");
        LogList.Items.Add("Send mail successly..");

        // back to normal cursor
        Cursor.Current = cr;

    }
    catch(InvalidOperationException err)
    {
        LogList.Items.Add("Error: "+ err.ToString());
    }
}

Hope this helped.
