Question

我已经创建了Web表单，现在我希望将这些数据存储在数据库中，然后通过电子邮件将表单发送到电子邮件中。这不起作用，因为它一直告诉我在＆＃39; /＆＃39;中存在服务器错误。应用。即使我重定向到Thankyou页面，我也包含了感谢页面的代码。请告诉我我做错了什么。

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using System.Web.Mvc;
    using Nordstromapp.Models;

    public SupportController(){
        _db = new NordstromEntities();
    }

    //
    // GET: /Form/[HttpGet]
    public ActionResult Create()
    {
        var categoryList = new SelectList(new[] {"How the Site Looks",
            "Product Offered", "How the site works", "General Comment"});
        ViewBag.CategoryList = categoryList;


        var concernList = new SelectList(new[] {"Shoes", "Handbags and accessories", "Beauty and Fragrance", "Sales", 
                                "Designe Collection", 
                                "Kids and Babies' collection", "Home gifts", "Service", "Other"});
        ViewBag.ConcernList = concernList;

        return View();
    }

    [HttpPost]
    public ActionResult Create(Models.Support support)
    {

        if (string.IsNullOrWhiteSpace(support.Question))
        {
            ModelState.AddModelError("Question", "Question is required");
        }
        if (ModelState.IsValid)
        { 
            // save to the database
            return Redirect("Thankyou.cshtml");
        }
            return Create();
        }
    }

查看：

@model Nordstromapp.Models.Support

@{

var Question = Request["Question"];
var First_name = Request["First_name"];
var Last_name = Request["Last_name"];
var Telephone_number = Request["Telephone_number"];
var Email = Request["Email"];
var errorMessage = "";
var debuggingFlag = false;
try {
    // Initialize WebMail helper
    WebMail.SmtpServer = "localhost";
    WebMail.SmtpPort = 21;
    WebMail.UserName = "";
    WebMail.Password = "";
    WebMail.From = "";

    // Send email
    WebMail.Send(to: Email,
        subject: "Help request from" + First_name,
        body: Question
    );
}
catch (Exception ex) {
    errorMessage = ex.Message;
}}

<!DOCTYPE html> <html> <head> <title>Request for Assistance</title></head><br><body><br><p>Sorry to hear that you are having trouble, Mr/Ms <b>@Last_name</b>.</p>
@if(errorMessage == ""){<p>An email message has been sent to our customer service
     department regarding the following problem:</p><p><b>@Question</b></p>}
else{<p><b>The email was <em>not</em> sent.</b></p>
    <p>Please check that the code in the ProcessRequest page has correct settings for the SMTP server name, a user name, 
       a password, and a "from" address. </p>
    if(debuggingFlag){
        <p>The following error was reported:</p><p><em>@errorMessage</em></p> }  } </body>

马上，我发现你结束行动的方式有几个问题。

您最后应该使用return RedirectToAction("Create")或简单的return View()，这样您就可以显示模型错误（如果您将助手添加到视图或验证区块中）。
您不应直接重定向到.chstml页面。取而代之的是return View("ThankYou")，或者更好的是，重定向到显示该页面的Get操作。（这是Post，Redirect，Get模式，以避免在用户刷新页面时重新发布数据的问题。）
