Import the System.Net.Mailnamespace.
导入System.Net.Mail命名空间。
The code will look similar to this:
代码将类似于以下内容：
MailMessage mail = new MailMessage();
SmtpClient smtpServer = new SmtpClient("smtp.gmail.com");
smtpServer.Credentials = new System.Net.NetworkCredential("userName", "password");
smtpServer.Port = 587; // Gmail works on this port
mail.From = new MailAddress("[email protected]");
mail.To.Add("[email protected]");
mail.Subject = "Password recovery";
mail.Body = "Recovering the password";
smtpServer.Send(mail);
P.S. You have a SQL injection vulnerability in the sample code. Use a SqlCommandobject with parameters instead of String.Format().
PS 你在示例代码中有一个 SQL 注入漏洞。使用SqlCommand带参数的对象而不是String.Format().
Using SqlDataReaderwould be a lot more efficient to check for a record instead of populating a DataSet.
使用SqlDataReader检查记录而不是填充DataSet.

Have a look at MvcMailer
MvcMailer provides you with an ActionMailer style email sending NuGet Package for ASP.NET MVC 3/4. So, you can produce professional looking emails composed of your MVC master pages and views with ViewBag.
MvcMailer 为您提供 ActionMailer 样式的电子邮件，用于发送 ASP.NET MVC 3/4 的 NuGet 包。因此，您可以使用 ViewBag 生成由 MVC 母版页和视图组成的具有专业外观的电子邮件。

It look like you are trying to send emails through GMail's SMTP service, which this SO question already covers: Sending email in .NET through Gmail
看起来您正在尝试通过 GMail 的 SMTP 服务发送电子邮件，这个问题已经涵盖：通过 Gmail 在 .NET 中发送电子邮件
The only thing that looks missing in your code is that you've set client.UseDefaultCredentials = true, I think you want to set this to falseand provide your own credentials. I've never tried using GMail to send through emails, but I'm guessing you'll need to use a GMail account as your credentials in order to authenticate properly.
您的代码中唯一看起来缺少的是您已设置client.UseDefaultCredentials = true，我认为您想将其设置为false并提供您自己的凭据。我从未尝试过使用 GMail 发送电子邮件，但我猜您需要使用 GMail 帐户作为凭据才能正确进行身份验证。

You should turn on the SMTP service in Window 7 :
您应该在 Window 7 中打开 SMTP 服务：
- go to Control Panel > Programs
- click "Turn window features ON or OFF"
- click Internet Information Service and click OK
- 转到控制面板 > 程序
- 单击“打开或关闭窗口功能”
- 单击 Internet 信息服务，然后单击确定
