正如标题所述，我正在尝试使用 GMail SMTP 从网站发送电子邮件，如 ASP.net 教程中所述:http://www.asp.net/web-pages/tutorials/email-and-search/11-adding-email-to-your-web-site .
尽早解决 ISAPI.dll 处理程序映射错误后，Webmatrix 错误控制台中不再有错误，只有“GET”和“POST”操作的成功标记；但是，网页返回 try catch 错误，“电子邮件未发送......”
在 SQL Server 管理器中，我尝试查看是否为邮件设置了服务器和 sa 管理员角色，但我看不到代理属性，据我所知，因为我有 SQL Management Studio 的 Express 版本。也就是说，如果服务器角色或邮件设置出现问题，肯定会生成错误消息吗？
有人可以快速浏览一下 SMTP 设置和整体代码以找出错误或建议吗？
(顺便说一下，我在示例代码中更改了我的电子邮件地址和密码。我的电子邮件地址在 webmail.username 和 webmail.from 中重复)
谢谢。
这是 EmailRequest.cshtml

编辑:
感谢 Mike 和 Gokhan 的帮助。今天早上我又仔细看了一遍。果然，昨晚从网页上发来了两封邮件； 因此，在某些时候所有因素都是正确的。
我尝试过端口 25、465 和 587，但是，我遵循的是教程，而不是“代码”。在我看来，该教程有点误导，并引起了困惑 - 我在错误的收件箱中寻找电子邮件。人们可能会认为问题报告通常会发送给主机，而不是报告问题的用户。
此外，即使正在发送电子邮件，仍然显示 try catch 错误。当然，应该通过犯错误来激活错误消息。仅当 [var errorMessage = "true";] 设置为 true 时，错误消息似乎才会出现。
我错过了什么？谁能解释一下本教程的 try catch 方法是如何工作的？
无论如何，这一切都很有效 - 我总是觉得迈克的评论令人放心。
我使用另一个教程将代码缩小到一页，并添加了一些表单验证，然后修改了代码，以便将电子邮件发送给主机而不是用户。
这是新的 EmailRequest.cshtml:
@{
Layout = "/_SiteLayout.cshtml";
Page.Title = "Compare";
Validation.RequireField("emailAddress", "customerName is required.");
Validation.RequireField("emailSubject", "customerEmail is required.");
Validation.RequireField("emailBody", "customerRequest is required.");
var message = "";
var companyname = Request.Form["emailAddress"];
var contactname = Request.Form["emailSubject"];
var employeecount = Request.Form["emailBody"];
try{
if (IsPost && Validation.IsValid()) {
// Send email
WebMail.Send(to:"ADMIN-EMAIL-ADDRESS.COM",
subject: Request.Form["emailSubject"],
body: "Help request from - " + Request.Form["customerName"] + " - " + "Email Subject - " + Request.Form["emailSubject"] + " - " + "Customer email - " + Request.Form["emailAddress"]
);
message = "Email sent!";
}
}
catch(Exception ex){
message = "Email could not be sent!";
}
}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Test Email</title>
<style type="text/css">
.validation-summary-errors {font-weight:bold; color:red; font-size: 11pt;}
.validation-summary-valid {
display: none;
}
</style>
</head>
<body>
<h1>Test Email</h1>
<form method="post">
@Html.ValidationSummary("Errors with your submission:")
<p>
<label for="customerName">Name:</label>
<input type="text" name="customerName" value="@Request.Form["customerName"]" />
</p>
<p>
<label for="emailAddress">Email address:</label>
<input type="text" name="emailAddress" value="@Request.Form["emailAddress"]" />
</p>
<p>
<label for="emailSubject">Subject:</label>
<input type="text" name="emailSubject" value="@Request.Form["emailSubject"]" />
</p>
<p>
<label for="emailBody">Text to send:</label><br/>
<textarea name="emailBody" rows="6"></textarea>
</p>
<p><input type="submit" value="Send!" /></p>
@if(IsPost){
<p>@message</p>
}
</form>
</body>
</html>
最后，这是我昨天没有发布的示例的 _AppStart 代码:
@{
WebSecurity.InitializeDatabaseConnection("StarterSite", "UserProfile", "UserId", "Email", true);
// WebMail.SmtpServer = "mailserver.example.com";
// WebMail.UserName = "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="44313721362a25292104213c25293428216a272b29" rel="noreferrer noopener nofollow">[email protected]</a>";
// WebMail.Password = "your-password";
// WebMail.From = "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="265f4953540b48474b430b4e43544366435e474b564a430845494b" rel="noreferrer noopener nofollow">[email protected]</a>";
// WebMail.EnableSsl = true; (add this if smtp is encrypted)
// WebMail.SmtpPort = 587;
}
编辑/编辑
提交后，我在保留文本区域框中的数据/值以及验证文本区域框时遇到问题。更多的研究让我想起了“required”属性，在这种情况下，它既可以做到这两点，还提供了一个简洁的工具提示。
因此，我删除了之前保留文本框值并验证表单的代码，并使用“required”属性代替 - 更加简洁。
此外，处理代码和成功消息现已内置到电子邮件请求页面中，因此不再需要 ProcessRequest.cshtml 页面。
这是向静态电子邮件地址发送请求的联系表单的完成代码 - 不要忘记您还需要使用 _AppStart 页面代码，除非您在页面中添加邮件服务器身份验证 - 您不需要两者都需要。但是，请注意，在页面中添加服务器电子邮件设置并不安全，因为用户将能够查看它们。我建议使用 _AppStart 页面，因为 Asp.net Razor 中以下划线开头的文件无法在线查看。

最佳答案
我很早以前就为一个项目编写过代码。试试这个。
public void SendEmail(string from, string to, string subject, string body)
{
string host = "smtp.gmail.com";
int port = 587;
MailMessage msg = new MailMessage(from, to, subject, body);
SmtpClient smtp = new SmtpClient(host, port);
string username = "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="67021f060a170b0227000a060e0b4904080a" rel="noreferrer noopener nofollow">[email protected]</a>";
string password = "1234567890";
smtp.Credentials = new NetworkCredential(username, password);
smtp.EnableSsl = true;
smtp.UseDefaultCredentials = false;
try
{
smtp.Send(msg);
}
catch (Exception exp)
{
//Log if any errors occur
}
}
