前提需要启用qq中smtp服务

<asp:TextBox ID="TextBoxYZ" runat="server" OnTextChanged="TextBoxYZ_TextChanged"></asp:TextBox>

         <asp:Button ID="Button1" runat="server" Text="发送验证"  OnClick="Button1_Click"  />

protected void Button1_Click(object sender, EventArgs e)
        {
            
            SmtpClient client = new SmtpClient("smtp.qq.com", 587);
            Random Rdm = new Random();
            //产生0到100000的随机数
            int iRdm = Rdm.Next(100000, 999999);
            MailMessage msg = new MailMessage("*********@qq.com", TextBoxYZ.Text, "验证码", iRdm.ToString());
            client.UseDefaultCredentials = false;
            System.Net.NetworkCredential basicAuthenticationInfo =
            new System.Net.NetworkCredential("*********@qq.com", "smtp密码");
            client.Credentials = basicAuthenticationInfo;
            client.EnableSsl = true;
            client.Send(msg);

            Session["YZM"] = iRdm;


        }

引用命名空间 using System.Net.Mail;

smtp密码不加空格放入“ ” 。

在Textbox中填入接受方邮箱，点击Button（发送验证）就可以接受到由发送方发的验证码。
