c# - SiteFinity C# 中的联系表

Question

我想通过一个简单的联系表单来完成基本功能，然后将表单电子邮件提交给某人。这在 asp.net 中很容易做到，但是一旦我将它作为用户控件上传，我就遇到了麻烦。你有我可以看的好例子吗？谢谢!

Answer 1

这与您在普通的 asp.net 页面中所拥有的相同，示例假定您使用的是最新版本的 Sitefinity 并且母版页上有 RadScriptManager 或 ScriptManager。

首先这是我的示例表单代码隐藏:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net.Mail;
using System.Text;
using System.ComponentModel;

public partial class UserControls_LandingPage_contactForm : System.Web.UI.UserControl
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void btnSubmit_Click(object sender, EventArgs e)
    {
        bool bSent = false;
        try
        {
            //create the email and add the settings
            var email = new MailMessage();
            email.From = new MailAddress(FromEmail);
            email.To.Add(new MailAddress(FromEmail));
            email.Subject = Subject;
            email.IsBodyHtml = true;

            //build the body
            var sBody = new StringBuilder();
            sBody.Append("<strong>Contact Details</strong><br /><br />");
            sBody.AppendFormat("Needs: {0}<br />", cboConsultationType.SelectedValue);
            sBody.AppendFormat("Name: {0}<br />", txtName.Text);
            sBody.AppendFormat("Email: {0}<br />", txtEmail.Text);
            sBody.AppendFormat("Number: {0}<br />", txtPhone.Text);
            sBody.AppendFormat("Comment: {0}<br />", txtMsg.Text);
            email.Body = sBody.ToString();

            //send the email
            var smtpServer = new SmtpClient();
            smtpServer.Send(email);

            //mark as sent ok
            bSent = true;
        }
        catch (Exception ex)
        {
            //send any errors back
            //add your own custom handling of errors;
        }

        //let the end user know if it was a success
        ScriptManager.RegisterStartupScript(this, this.GetType(), "alert", "alert('" + (bSent ? SuccessText : FailureText) + "');", true);
    }

    //properties    
    public string FromEmail
    {
        get { return _fromEmail; }
        set { _fromEmail = value; }
    }
    public string Subject
    {
        get { return _subject; }
        set { _subject = value; }
    }
    public string SuccessText
    {
        get { return _successText; }
        set { _successText = value; }
    }
    public string FailureText
    {
        get { return _failureText; }
        set { _failureText = value; }
    }

    //fields
    private string _fromEmail = "info@example.com.au";
    private string _subject = "Website Enquiry";
    private string _successText = "Thank you for submitting your details we will be in touch shortly.";
    private string _failureText = "There was a problem submitting your details please try again shortly.";

}

ASCX 代码:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ContactForm.ascx.cs" Inherits="UserControls_LandingPage_contactForm" %>
<fieldset>
    <div class="focus">
        <label>
            I need...</label>
        <asp:DropDownList ID="cboConsultationType" runat="server" CssClass="select sub web">
            <asp:ListItem Value="I Need A New Web Site">A completely new website</asp:ListItem>
            <asp:ListItem Value="Web Site Upgrade">My website upgraded</asp:ListItem>
            <asp:ListItem Value="Application Design">An application </asp:ListItem>
            <asp:ListItem Value="An ecommerce website">New Ecommerce website</asp:ListItem>
            <asp:ListItem Value="Other">Other</asp:ListItem>
        </asp:DropDownList>
    </div>
    <ul>
        <li>
            <asp:Label EnableViewState="false" ID="lblErrorMessage" runat="server"></asp:Label>
        </li>
        <li>
            <asp:Label EnableViewState="false" ID="lblName" AssociatedControlID="txtName" runat="server"
                Text="Name"></asp:Label>
            <asp:TextBox ID="txtName" runat="server" ValidationGroup="ContactValidation"></asp:TextBox>
            <asp:RequiredFieldValidator ID="RequiredFieldValidatorName" runat="server" ValidationGroup="ContactValidation"
                ControlToValidate="txtName" ErrorMessage="Name is required">*</asp:RequiredFieldValidator>
        </li>
        <li>
            <asp:Label ID="lblPhone" runat="server" AssociatedControlID="txtPhone" EnableViewState="false"
                Text="Phone"></asp:Label>
            <asp:TextBox ID="txtPhone" runat="server" ValidationGroup="ContactValidation"></asp:TextBox>
            <asp:RequiredFieldValidator ID="RequiredFieldValidatorPhone" runat="server" ValidationGroup="ContactValidation"
                ControlToValidate="txtPhone" ErrorMessage="Phone is required">*</asp:RequiredFieldValidator>
        </li>
        <li>
            <asp:Label ID="lblEmail" runat="server" AssociatedControlID="txtEmail" EnableViewState="false"
                Text="Email"></asp:Label>
            <asp:TextBox ID="txtEmail" runat="server" ValidationGroup="ContactValidation"></asp:TextBox>
            <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ValidationGroup="ContactValidation"
                ControlToValidate="txtEmail" ErrorMessage="Email is required">*</asp:RequiredFieldValidator>
            <asp:RegularExpressionValidator ID="RegularExpressionValidatorEmail" runat="server"
                ControlToValidate="txtEmail" ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"
                ValidationGroup="ContactValidation" ErrorMessage="Email address is invalid">*</asp:RegularExpressionValidator>
        </li>
        <li>
            <asp:Label ID="lblMsg" runat="server" AssociatedControlID="txtMsg" EnableViewState="false"
                Text="How can we assist you?"></asp:Label>
            <asp:TextBox ID="txtMsg" runat="server" TextMode="MultiLine" Rows="5" Wrap="true"></asp:TextBox>
        </li>
        <li>
            <asp:Button ID="btnSubmit" runat="server" EnableViewState="false" CssClass="submit"
                Text="Send" ValidationGroup="ContactValidation" OnClick="btnSubmit_Click" />
        </li>
    </ul>
</fieldset>

然后您需要注意的唯一其他项目是在 web.config 中您需要修改电子邮件的 system.net 设置:

 <system.net>
 <mailSettings>
   <smtp from="mailmaster@yourdomain.com">
     <network host="smtp.yourdomain.com" userName="Your_Username" password="Your_Password" port="25" />
   </smtp>
 </mailSettings>
</system.net> 

然后上传控件或修改您的 web.config 。然后，如果您的 SMTP 服务器设置正确，表单应该可以正常发送。

希望对您有所帮助。
