如何在 asp.net 和 c# 中创建联系表单？

Question

如何创建联系表单以在 asp.net 和 C# 中单击按钮时发送邮件？以下是我拥有的联系表单中的代码，当单击按钮（#Button1）时，我想将表单提交到电子邮件：“name@mail.com”但不刷新页面，仅发送表单并切换一个 div (#submit)？

<form id="form1" runat="server">  

                        <div class="input-boxes">

                            <div class="left-inputs">

                                    <input name="name" id="name" type="text" placeholder=" " runat="server" required>
                                    <label for="name">Full Name *</label>
                                </div>
                                <div class="input-place required second" style="margin-bottom: 0px !important;">

                                            <input name="web-design" type="checkbox">
                                            <span class="checkmark"></span>

                                        <label class="container">Web Development

                                            <asp:CheckBox ID="CheckBox1" runat="server" />
                                            <span class="checkmark"></span>
                                        </label>
                                        <label class="container">App Design

                                            <asp:CheckBox ID="CheckBox2" runat="server" />
                                            <span class="checkmark"></span>
                                        </label>
                                        <label class="container">App Prototyping

                                            <asp:CheckBox ID="CheckBox3" runat="server" />
                                            <span class="checkmark"></span>
                                        </label>
                                        <label class="container">E-Commerce

                                            <asp:CheckBox ID="CheckBox4" runat="server" />
                                            <span class="checkmark"></span>
                                        </label>
                                    </div>
                                </div>
                            </div>
                        </div>
                        <div class="send-button">
                          <asp:Button ID="Button1" runat="server" Text="Send" OnClick="Button1_Click" />
                        </div>

    </form>

这是点击按钮时需要切换的div：

<div class="form-send" id="submit">
            <div class="dialog">
                <img src="Content/icons/success.svg">
                <h2>Thanks for reaching us!</h2>
                <p>We appreciate you contacting us. Our team will get back to you shortly.</p>
                <div class="close-confirmation">Close</div>
            </div>
        </div>

服务器端代码：

protected void SendMail()
{
    // Gmail Address from where you send the mail
    var fromAddress = "Gmail@gmail.com";
    // any address where the email will be sending
    var toAddress = YourEmail.Text.ToString(); 
    //Password of your gmail address
    const string fromPassword = "Password";
     // Passing the values and make a email formate to display
    string subject = YourSubject.Text.ToString();
    string body = "From: " + YourName.Text + "\n";
    body += "Email: " + YourEmail.Text + "\n";
    body += "Subject: " + YourSubject.Text + "\n";
    body += "Question: \n" + Comments.Text + "\n";
    // smtp settings
    var smtp = new System.Net.Mail.SmtpClient();
    {
        smtp.Host = "smtp.gmail.com";
        smtp.Port = 587;
        smtp.EnableSsl = true;
        smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
        smtp.Credentials = new NetworkCredential(fromAddress, fromPassword);
        smtp.Timeout = 20000;
    }
    // Passing values to smtp object
    smtp.Send(fromAddress, toAddress, subject, body);
}


protected void Button1_Click(object sender, EventArgs e)
{
    try
    {
        //here on button click what will done 
        SendMail();
        DisplayMessage.Text = "Your Comments after sending the mail";
        DisplayMessage.Visible = true;
        YourSubject.Text = "";
        YourEmail.Text = "";
        YourName.Text = "";
        Comments.Text = "";
    }
    catch (Exception) { }
}

在按钮提交上，您可以执行操作打开确认对话框。
