Question

我正在使用下面的代码创建LostPassword函数。当用户输入他们的电子邮件时，他们会获得包含要重置的令牌的链接的密码。在我的控制器中，我有GenerateTokenPassword方法（在WebSecurity下），但它抛出了这个错误：

错误：无法将类型'string'转换为'int' 行：var token = WebSecurity.GeneratePasswordResetToken（（foundUserName）.ToString（），1440）;

当我调试时，我在foundUserName字段中获取了用户名，它是一个字符串。 1440是令牌到期时的超时，我提供了一个int来开始。它看起来是什么int？

任何想法可能是什么？

谢谢，

    message.IsBodyHtml = true;
    SmtpClient smtp = new SmtpClient();
    smtp.UseDefaultCredentials = false;
    smtp.Credentials = new System.Net.NetworkCredential("mymail", "mypass");
    smtp.Host = "smtp.gmail.com";
    smtp.Port = 587;
    smtp.EnableSsl = true;
    smtp.Send(message);

    return View();
    }

出现编译器将1440值解释为字符串，您可以尝试为它声明一个显式int变量并传递它。

或者，给定tokenExpirationInMinutesFromNow是一个可选参数，默认为1440，然后您可以完全省略它

var token = WebSecurity.GeneratePasswordResetToken((foundUserName).ToString());

GeneratePasswordToken在MVC 5中抛出奇怪的错误（asp.net身份） - 忘记密码
